Home theatre subwoofers buying guide

How to choose the best one for your surround sound system

In this article: tips on choosing the right powered subwoofer for your home theater. What size should you get? Does sealed or ported matter? Where should your sub go? We'll cover all of these questions and more to help you get the best bass possible.

I discovered my passion for hard-hitting bass as a movie- and music-loving teenager back in the ‘90s. My friends and I spent countless hours talking shop and tweaking our systems. A couple of decades later, my thrill for great bass hasn’t waned one bit. I still get goosebumps when a surge of low-frequency punch sweeps through my living room. 

Having the right powered subwoofer makes a real difference in the quality of your home theater experience. I've put this guide together to help you choose the best one for your system. We'll look at the key factors to consider while shopping, as well as which features and specs really matter.

How do you choose the right size subwoofer?

One of the first things to consider is what size sub you want. Generally speaking, the larger the surface area of the woofer, the deeper it will play — that's indicated by the sub's frequency response, which is measured in Hz.

It may be tempting to go for the largest sub you can find. But bigger is not always better. It's important that your sub blends in seamlessly with your other speakers to create an immersive listening experience.

If your system consists of compact satellite or bookshelf speakers, an 8" or 10" sub will pair nicely with them. On the other hand, if you have big floor-standing speakers and a huge center channel, a 12" sub is a better sonic match. 

Do you have a big, open living room? Then a large subwoofer is worth considering since it moves more air (and thus produces more bass). Is this sub going into a cozy den or bedroom? Then a smaller size may make better sense so you don't overwhelm your space.

Choose a sub that appropriately matches the size of your room as well as the size of your other speakers.

How much bass do you want?

The question of "how much sub should I get?" is a personal consideration. I'm really into dinosaur and spaceship movies, so I like bass that thunders and makes my room quake. I went through several smaller subs before landing on my current 12" Klipsch, which suits my room and taste for bass perfectly.

If your household is more likely to binge-watch comedy shows or kids movies, you won't need nearly as much "oomph." A smaller sub is the way to go, even if you have a big room. 

My colleague and fellow home speaker enthusiast Emily has the same beefy Klipsch model that I have, and loves it.

How much power do you need?

One of the best things about a powered subwoofer is that its amplification is built right in. That means you don't need to shop for a separate amp to drive it. 

So how much power do you actually need? Honestly, there's no cut-and-dry answer to that (and I'm not sure boring you with the engineering details is helpful). But generally speaking, the higher the amp's wattage, the more powerful and impactful the bass. My advice is to go for as much power as your budget allows, but don't overspend for higher wattage just for the sake of a bigger number. 

The spec to pay attention to is the sub's continuous power, or RMS rating. You'll also see a "peak power" rating listed on many powered subs. While flashy on paper, this measurement doesn't factor much into real-life performance, and is safe to ignore during your selection process.

How much power do you need?

The customer-favorite Polk Audio PSW111 pairs an 8" woofer with a 150 amplifier — perfect for small rooms where space is at a premium.

Which is better, sealed or ported?

You'll see two main types of subwoofer enclosures: sealed and ported. Sealed enclosures (also known as acoustic suspension) are just as they sound: air doesn't move in or out. This tends to make them quick and responsive with tight, accurate bass.

Ported boxes (or bass reflex enclosures) have a built-in air vent that helps reinforce low bass output. You'll typically get more powerful bass from a ported enclosure without needing as much power. But there's a tradeoff: ported boxes can be considerably larger than their sealed box counterparts.  

So which sounds better? There's no clear-cut winner when it comes to home theater applications. Both designs offer clean, hard-hitting bass for movie soundtracks.

But if you listen to music on your home theater system, the type of enclosure can have a more audible impact. If you like jazz, classical, or other acoustic genres, I recommend a sealed enclosure. If you prefer hard rock, hip-hop, or EDM, a ported design is generally a better choice. 

SVS bass.

The massive 13-1/2" SVS PB-4000 uses three carefully tuned ports to reinforce low-frequency output.

What are passive radiators? 

Some subs use passive radiators to reinforce bass output. These are unpowered cones within the sub enclosure that move in tandem with the powered driver. Passive radiators add extra "oomph" to the subwoofer's output without increasing the sub's amplifier size.

Small sub with passive radiator.

Definitive Technology's SuperCube® 6000 matches a powered 9" woofer with two 10" passive radiators for room-shaking bass in a roughly one cubic foot enclosure.

Where should your sub go?

Measure the area where you plan on putting your sub to get a sense of its footprint. You'll want to make sure that the sub you're considering will fit comfortably into your desired location.

Don't forget that you'll need to connect your sub to an outlet for power, as well as to your receiver for signal. Check out my article on home theater speaker placement for tips on arranging your system.

Tip: Use an isolation platform to stop to the rattling

Quick story: my living room has glass bookshelf and fireplace doors, along with tall windows that line three of its walls. All of these used to rattle like crazy when bass hit during movies. It drove me nuts!

One day I decided that I'd had enough. I bought an isolation platform to decouple my sub from the hardwood floor. Voila! Just like magic, the rattling and vibrations instantly disappeared. I even had to dial the sub back because the bass was suddenly stronger. It is without a doubt the best money I've ever spent on my system.

Add a second sub for better bass in your room

Home theater receivers use an RCA output for their subwoofer connection (that's the ".1" in a 7.1 system). Some receivers have two subwoofer outputs, which let you easily add a second sub to your system.

Using two subs improves bass distribution around your room, which is especially helpful if you have multiple seating locations. A dual-sub setup is also a great way to go if you crave lots of bass in your room. Here are home theater receivers that have two subwoofer outputs.

Room with two subwoofers.

Use two subwoofers in your room to hear balanced, chest-thumping bass from all of your seats.

Tailoring your sub's sound to your room

We've seen some pretty cool advancements in the world of subwoofer technology. The biggest is room-correction software that lets you shape your sub's sound to match your room's acoustics.

Some subs have advanced digital signal processing built right in. For example, Dynaudio's Sub 6 has onboard controls for adjusting its DSP system. This lets you precisely tailor the sound to get the best performance in your space.

An even simpler way of dialing-in your sub is by using an app on your phone. "Smart subs," like ELAC's Debut 2.0 SUB3030, use your smartphone's microphone to capture a near-field measurement of the sub's output. It then compares how things sound from your seat, and automatically smooths out the EQ curve to give you the best sound. 


One benefit to a smart sub is that there are no knobs or dials to fiddle with on the rear panel. Just fire up the app on your phone to make changes.

Should you consider a "wireless" subwoofer?

Earlier I mentioned that your sub needs to connect to your home theater receiver for signal. Usually this means running and concealing a long cable from one part of the room to another (everyone's favorite, right?).

A growing number of subs can receive signal wirelessly from a transmitter than connects to your receiver. Some subs include the transmitter in the box. For others, it's available as an optional accessory.

There's also a wireless kit that transforms virtually any sub into a "wireless sub." Remember that your sub still needs to plug into an outlet for power, or better yet a power protection device.

MartinLogan's SW2-TRD wireless subwoofer adapter kit uses a transmitter and receiver to send signal to your sub without using a long cable.

    Thanks for the article. Was very informative. I am struggling... I have an Onkyo TX NR717 driving Polk RTI A6 fronts with a CSI A6 center. I am getting in FXI A4 rears. I feel like I should stay in the Polk family, but don't understand the difference subs they offer. I have a 12 * 18 media area that is open on the back. I am leaning towards the DSW Pro 550, but don't understand how the HTS series compares. What are you thoughts?

    Kramer Crane from Crutchfield

    on 9/4/2020

    Hi Ed, thanks for your question. That's a great system you have in the works.

    As for the sub, the DSW PRO 550 is an oldie but a goodie, making its debut at Crutchfield back in 2010. We no longer carry that model, but Polk's HTS subs offer tight, clean bass and are quite popular with our customers. In that series, the HTS 12 is the best option for your large, open room, and will pair nicely with your RTI and CSI series speakers.

    I should add that there isn't really a sonic benefit to staying with the same brand for your sub as you have for your main speakers. In the same price range, the SVS PB-1000 may be a better choice for your room. It has a 300-watt amp, and plays down to 19 Hz. It's worth a look, especially if you aren't super limited on floor space.

    Hi Kramer, Thanks for the article. I'm planning to build a home theater. Media room size is 16' x 16' with 8 foot ceiling. Planning to start with 5.2.4 setup and expand later to 7.2.4. Thinking to go with two 10" or 12" subs. Are two subs an overkill for the room size? And could you please recommend a good sub under $500 that works with my setup.

    Kramer Crane from Crutchfield

    on 9/1/2020

    Hi Sarat, thanks for reaching out. That's a fun room you have planned!

    I'm in the camp that you can never have "too much" sub in your room, since you can always dial back the output level. That said, it really comes down to space. You might find a single 12" or two 10" subs more manageable than a pair of 12" models. You can also start with a single sub and add a second one down the road, as well.

    I believe the best bass you can get for about $500 is the SVS PB-1000. Check out the reviews — folks love this sub.

    Hi Kramer thank you for the great article, I have a 11 'x 30'x10'room and I am planing to go for KEF Q950 pair, Q650C, 2 pair of Q50a atmos surround and 4 atmos. Suggest me on best 9.2 amplifier for kef (Denon / marantz / Yamaha) and matching sub (kef or polk or svs or klipsch) and should i go for 2 subs? Thank you

    Kramer Crane from Crutchfield

    on 8/27/2020

    Hi Vijay, that's a great system you've got in the works. Take a look at the Denon AVR-X3700H and SVS PB-2000 Pro. They will pair with your KEF speakers nicely.

    As for one sub or two, adding a second sub almost always improves bass performance since you get more evenly distributed sound. You might start with one sub, and expand from there based on how things sound.
  • Rob from Tiburon, CA

    Posted on 8/19/2020

    Hi Kramer I have recently bought a pair of KEF LS50W speakers and I'm looking to pair a subwoofer to them. My room is about 25 x 18 ft, hardwood floors and three tall windows, not damped. I don't play music that loud as I'm cognizant of my neighbour's, but want good low volume, great impact bass. Mostly music though but I'll probably find the time to watch more movies if I get the bass set up right. Do you rate the KEF T2 as an option or something else? Thanks Rob

    Kramer Crane from Crutchfield

    on 8/21/2020

    Hi Rob, thanks for reaching out. I also own the KEF LS50 Wireless, and found that adding a small powered sub rounded them out nicely. I haven't heard KEF's T-2 personally, but I imagine it would be a good fit if you go that route.

    If you're looking to maintain a relatively small footprint, take a look at the Cambridge Audio Minx X301. The depth of bass it delivers is impressive for its size. It's also super clean throughout its volume range, so you get tight, clear bass even at low volume levels. You can dial-in the crossover to blend smoothly with the LS50s, and enjoy an exceptional 2.1 system that doesn't take up a ton of space. I think the X301 would be an excellent fit for your room and speakers.
  • Raj from Coimbatore

    Posted on 8/13/2020

    Hi Kramer, I have a 11 'x 20' room with a 10 foot high ceiling. I have KEF Q950 pair, Q650C, 2 pair of Q50a atmos surround with a 9.2 140 watt Yamaha RX-A2080 amplifier. Suggest me on best matching sub (polk or svs or klipsch) and should i go fo 2 subs? Thank you

    Kramer Crane from Crutchfield

    on 8/17/2020

    Hi Raj, thanks for your question. I'd take a look at the SVS PB-2000 Pro. It's large enough and powerful enough to fill your room with tight, clean bass. And since it's one of SVS's "Pro" models, it has app control and room equalization for matching it to the acoustics of your space.

    I think a single sub is sufficient for your system, but we have plenty of customers who choose a dual-sub setup. If you find the distribution of bass throughout your room isn't as even as you'd like, adding a second sub is a solid next step.
  • Greg from Tacoma

    Posted on 7/22/2020

    I have a Klipsch R-120SW and bought a second one. I only have space on one side of my theater shelf unit. Is it recommended to have subwoofers on each side of the couch, left and right ends, or could I place them directly behind the couch, behind each listeners back?

    Kramer Crane from Crutchfield

    on 7/22/2020

    Hey Greg, thanks for your question. The short answer is that spacing the subs apart from each other is your best bet if you can do it. This helps fill in gaps in the sound if the room's acoustics lend to uneven performance. But if they can't be spaced apart, or if there's only room for the pair of them in the back of the room, that's okay — the second sub will still help even out the bass response in your room.

    In your shoes I'd try the subs in as many different placement configurations as possible to see which one sounds the best. And if they both end up behind the couch, I think you'll still get great bass. Let me know how it turns out!
  • Kramer Crane from Crutchfield

    Posted on 7/20/2020

    Hi Charles, you've got a nice system in the works! That Polk isn't a bad sub, but with only 50 watts of power you might be underwhelmed.

    Personally, I'd go with a sub that has a little more "oomph" to get the kind of tight, musical bass that best matches your Motion 15s. In particular, the Cambridge Audio Minx X201 is fantastic choice to pair with your speakers, as well as with your room. Plus, it hardly takes up any space!

    I do recommend putting your sub on an isolation platform (like the IsoAcoustics ISO 200 Sub) to get the best sound.

  • Charles from Tulsa

    Posted on 7/17/2020

    I have a Marantz PM 1700N that I purchased from Crutchfield last week. Also have a pair of Martin Logan 15's on the way. Do you think the Polk audio PW 10 would be a sufficient sub in a room 12 feet wide and 19 feet long? I just like for bass to enhance the sound and there is no need for it to be overpowering.

  • Peter Condiles from New York

    Posted on 7/15/2020

    Hi Kramer, I'm looking at getting a sub to replace a klipsch R-12SW. I'm disappointed in lack of how low it goes. So I'm considering Klipsch SPL-150, SVS-PB3000 (& possibly SVS- SB3000). Which do you suggest. I have Klipsch R-28F pair front, R- center, side and rear, 7.2 receiver. Sony Z9D tv. Thank-you.

    Kramer Crane from Crutchfield

    on 7/15/2020

    Hey Peter, thanks for reaching out. If size is not an issue, the PB-3000 is an exceptional subwoofer, and even in a large room will not leave you wanting in terms of depth and punch. The SB-3000 is another excellent option if the ported enclosure is too large. It's also 28 pounds lighter, despite using the same driver and amplifier as the PB-3000. That said, if you have the room for the ported enclosure, it will hit lower and harder, and that's the direction I'd go in your shoes — its low-frequency extension is simply staggering.

    Whichever enclosure type you land on, I highly recommend adding SVS' SoundPath Subwoofer Isolation System to decouple your sub from the floor. Your windows and picture frames will thank you :)

    Please let me know if we can help with anything else, and happy listening!

    I really appreciate the effort Crutchfield puts into articles and how-to guides. I'm currently using a Marantz 7011 in a 6.0.2 configuration using Klipsch Forte and Quartets. So all 6 have a passive radiator on the back. I'd like to add a dual sub setup, but I don't know if SPL-100s or SPL-120s would be a better match. Any thoughts or questions I should be asking would be appreciated.

    Kramer Crane from Crutchfield

    on 5/26/2020

    Hi James, thanks for reaching out. I'm so glad you're finding our content helpful.

    I'm a big fan of the quality of bass that Klipsch subs dish out. I had a 12" model in my own system for quite some time, and thoroughly enjoyed it. I'd say that the decision to go with dual 10s or dual 12s mostly depends on your room size. If you have the space, the 12" subs will provide deeper bass extension and more overall "oomph." That's the way I would go in your shoes, so long as your room supports them.

    Your Marantz SR7011 will let you calibrate your two subs independently, so you'll have terrific-sounding bass that's well-optimized for your space.

    My room size is 15x18ft. I have recently replaced old HK Avr 155 to Onkyo 686 and front speakers to Elac debut 6.2. Rest of the old Harman Kardon HKTS speakers are used as atmos, center and satellite speakers. I am still not happy with the system, my old sub distorts sometimes (not always) what could be the reason? I want to replace the sub now and may be old speakers too later. Kindly suggest a good sub ($500 range) which will amply provide the bass.

    Kramer Crane from Crutchfield

    on 5/26/2020

    Hi Karan, thanks for reaching out. It's hard to say what's causing your sub to distort. However, you can certainly get fantastic bass for your size room with a new sub.

    My best suggestion for bass is to go with the SVS PB-1000. It's the best sub for around $500 that we carry in my opinion, and will be a terrific fit with the rest of your system. Check out the reviews to get a sense of how happy our customers have been with it — it's a rockstar.

    Hi Kramer, I have a 12 'x 18' room with a 12 foot high ceiling. I have 2 klipsch rp8000f, 2 klipsch rp502s, 1 rp504c and two rp500sa with a 9.2 100 watt x channel amplifier. with two 12 subwoofers is it ok or should I go for two 15? Thank you

    Kramer Crane from Crutchfield

    on 5/26/2020

    Hi Jose, thanks for reaching out. That's one heck of a nice system you've got there!

    15" subs can be terrific, but I think a pair of them might actually be overkill in your space. In your shoes, I'd go with the two 12s for the best overall performance. You'll get strong, evenly dispersed bass that will compliment the rest of your speakers nicely.

    I am putting together a home system and my room is about 15×15. The reciever I am looking at is 7.2. If I add 2 subs can they be smaller to receive the benefit of 1 large or should I go 2 large subs

    Kramer Crane from Crutchfield

    on 5/26/2020

    Hi Billy, thanks for reaching out. Generally speaking, I'm of the mindset that it's better to be able to dial a large sub back than not have enough "oomph" for the type of bass you enjoy. If you can comfortably fit two larger subs in your room then I'd lean in that direction. If you end up going with a single sub, I'd choose the biggest, baddest one that will fit your room!

    Posted on 4/29/2020

    Hi Kramer, I'm looking for a subwoofer for a small room (10x12) that is used primarily for listening to jazz and classical but also hip-hop. I got some gift cards for my birthday and excitedly bought a Yamaha NS-SW050. I just got it and I'm not sure it's what I want. More troublesome is the fact that my receiver is from 1989 and has no subwoofer port (I'm unable to connect the NS-SW050 to it. I'm clearly and woefully inexperienced...). I want a tight and accurate sound in my sub. I have a budget of around $150-$200. What do you suggest? Thanks for your time, Blane

    Kramer Crane from Crutchfield

    on 4/30/2020

    Hi Blane, thanks for reaching out. What you're looking for is a subwoofer that has speaker-level inputs, like the Polk Audio PSW10. You'll run your existing speaker wires into the sub, which allows it to extract bass information. Then, you'll run a separate set of wires from the sub to your speakers. This will give you the tight, clean bass you're looking for. (BTW, that Polk sub is one heck of a nice value right now)!

    Hello! I'm making my first home theater set up. I'll use a pair of Klipsch r-51m and a r-52c like front speakers and a pair of Klipsch r-41m like rear speakers. I have two options for subwoofer: Klipsch r-12sw or Klipsch r-100sw. This set up it's for my bedroom, that isn't very big. Which do you think is better in this case?

    Kramer Crane from Crutchfield

    on 4/22/2020

    Hi Kevin, thanks for reaching out. My apologies for taking so long to reply; this one slipped through the cracks on my end.

    The Klipsch R-100SW is a fantastic choice for your bedroom system. It hits deep and hard, and will provide plenty of bass for your room. The 12" is likely overkill for this space, so I'd stick with the 10" option in your shoes. Happy listening!

    I will be setting up a home theater system in my basement with laminate flooring. I also like deep hitting bass for music but mostly it will be for action movies. Do you think a down firing sub or front facing sub will work better for this environment?

    Kramer Crane from Crutchfield

    on 9/9/2019

    Hi Aaron, either configuration is fine, and I'm not sure there's a strong case to be made for one over the other. There are two things that definitely will impact your bass experience though.

    The first is positioning your sub within your room so it creates the best sound possible — check out this guide for tips. The second is using an isolation platform to decouple the subwoofer from the floor. Especially with laminate, this will significantly reduce reflections and vibrations that will otherwise color what you're hearing.

    Posted on 6/17/2019

    I bought the Klipsch r-820f with a Klipsch r-405c center from here for my living room setup. Mainly for movies with most being action I want a bigger punch than the towers are giving me. This is my first HT setup and never owned a subwoofer before but am thinking about the Klipsch SW112 that you own. Will this give me added punch vs towers during action movies or is the difference negligible and should I look towards a more powerful sub? Dual subs is not an option and a lot of the 15" subs are bigger than I want Thanks!

    Kramer Crane from Crutchfield

    on 6/17/2019

    Hi Steven, adding a subwoofer will change your life! Seriously, it's a completely different experience watching a movie with a good sub versus not having one at all.

    The SW112 is an excellent choice in terms of bass. I have large tower speakers with dual 8" drivers in each, and my sub blows them away in terms of bass. Let me know what you think after you watch your first movie with it!

    You mentioned satellite, bookshelf early on and pairing them with a 8 or 10". Compared to floor-standing with a 12". I have older larger klipsch bookshelf s with dual 6" woofers. What are your thoughts on pairing for them? I am looking, thinking about replacing a aging 12" mk and am not sure what to include or exclude in reviews of possible replacements. Thx Mike

    Hi Mike, you can comfortably go with as large as sub as you like. With smaller satellite speakers (say with single 5-1/4" woofers), a 12" sub can just plain be too much bass. But since you have rather robust Klipsch bookshelves, you don't need to worry about the sub overpowering them. Go as big as you'd like!

    Hi Kramer, Will a 10 inch sealed sub add anything different than turning the volumn up on my Definitive Tech. Mythos STS (the super cubes built in)? I would hate to spend a thousand dollars for nothing. Thanks

    Hi Lou, adding a 10" sub to another part of your room will help even out the bass distribution. But I don't know that'd you'd hear a big difference in terms of overall impact. If you have the space, a 12" ported sub might be worth considering.

    I thought I had my mind up & was ready to order the MartinLogan Dynamo 700W. It looks like an amazing sub At an even more amazing price! However, now I'm learning it's an enclosed sub. My previous 2 subs were ported. Whatever sub I purchase will be for home theatre use only. Not music listening. Would I be better off choosing a ported sub for my home theatre usage? Both subs I had in past we're ported but also part of home theatre in box setups & I know those kits aren't usually the highest quality, so maybe I'll find improved sound regardless of enclosed or ported? Lol, my struggle is real! Any suggestions?

    Kramer Crane from Crutchfield

    Hi Jon, you raise an age-old question about sealed versus ported enclosure performance. In this case, I wouldn't worry about it at all. MartinLogan is one of the best speaker designers around, and the Dynamo 700W is a terrific subwoofer for home theater. We've had a ton of folks that have been thrilled with this one in their surround sound system.

    That said, we offer a 60-day satisfaction guarantee, so if for some reason it didn't perform the way you expected you can always return or exchange it.

    I have a Martin Logan system and my dynamo w 1000 subwoofer stopped working, specifically the amp. The cost to replace the amp is almost cost of new powered speaker. Can I use just the speaker of old sub paired with new dynamo 1000 as a passive sub ? Thank you

    Kramer Crane from Crutchfield

    on 10/15/2018

    Hi Joey, I'm sorry to hear your sub isn't working anymore! I'm not clear how you'd try to utilize the non-working sub as a passive woofer in that scenario. I'd stick with a single new sub as your best bass route at this point. Happy listening!

    I have a large room (~20' x 32'). Do you think I would be better off with 2 Klipsch R112SW's, or 1 Klipsch R115SW with it's lower frequency response? My main front speakers are Klipsch RP280's.

    Kramer Crane from Crutchfield

    on 9/19/2018

    Hi Kevin, that's an excellent question — one that I think comes down to individual preference. I have the Klipsch Reference R-112SW myself, and absolutely love it. I personally would prefer two 12" Klipsch subs over one 15" sub in a large room like yours, since they would provide much more evenly distributed bass (and ultimately a more immersive home theater experience).

    I purchased a Polk audio dsw I believe.. and a few months back it started to make a loud thumping sound turned on and off.. now there is a humming noise with a whizzing sound coming from it without the receiver turned on. Any solutions?

    Hey Andrew, I'm sorry to hear you're having trouble with your sub. If you purchased it from Crutchfield, please give our tech support folks a call (their phone number is on your invoice). You can also reach Polk's customer service at 1-800-377-POLK (7655) to troubleshoot the issue. Hope you're back up and running soon!

    I have a wired sub now, and am considering adding a second. Would a wireless sub work well with a wire, or would the wireless have just enough lag to be noticeable?

    Kramer Crane from Crutchfield

    on 8/28/2018

    Hey Chris, the signal transmission for wireless subs is pretty much instantaneous. I'd have no problem pairing a wireless sub with your existing model in terms of timing.

    Hey Andy, you'd be hard pressed to beat another pair of the B6s for your rear channels. They are on sale right now, and would give you a perfectly voice-matched system front and back.

    As for a sub, I highly recommend the ELAC Debut S10EQ. It offers excellent bass for its size, and can be controlled from your phone. It's the best match for the money for your B6s.

  • Andy from Sierra Madre

    Posted on 4/23/2018

    I have a pair of elac debut B6's with a Pioneer Elite Model: VSXLX102 Receiver. I want to add a sub and a pair or surround speaker without breaking the bank but that will pair nicely with what I have. What do you recommend?

  • Kramer Crane from Crutchfield

    Posted on 3/5/2018

    Hi Suresh, the short answer is yes. That small difference in frequency response can indeed made a big difference in the depth and accuracy of low-note bass performance. It's one of several key factors that play into how well a given sub sounds, and plays an integral role in how "visceral" the bass feels when it hits.

  • Suresh from Chicago

    Posted on 3/5/2018

    Does frequency range matter in selection? I see some starting at 27HZ and most at 30HZ with big difference in price. Does the difference of 3HZ make perceivable listening experience? Thanks.

  • Kramer Crane from Crutchfield

    Posted on 12/6/2017

    Dave, there's no issue with a subwoofer (or any speaker for that matter) that's not video-shielded being near your LED TV. In the old days of tube TVs, the magnetic energy from a speaker could damage the picture tube if it was too close. That's not an issue anymore, so it's not something to worry about.

    The potential concern I'd have about placement that close to the TV is the quality of bass that you'll get. If you can, I recommend trying the sub out in a few different locations around the room to see where it sound the best.

  • Dave from Lapeer

    Posted on 12/6/2017

    I'm thinking on an SVS pb2000 sub, but it would have to be with in an inch of my led tv screen. My question is, would that harm the screen or is the SVS video shielded?

    Hi, I am planning on a HT for my new home.. have decided to go with Elac F5 Elac C5 Yamaha RX481 or 581amp , Surround - Wharfedale Diamond 10.DFS. I am completely confused for the Sub.. have auditioned a few from Wharfadale, Elac, PSB125, polk and paradigm all were 8/10/12 inch with 100 or 125 watt output..PSB subseries 125.. is what I was most impressed with. Given that they sounded loud given 8inch size and 125 watt output. Unfortunately I am unable to see any reviews on it... other brands were good but not upto the output of PSB... not able to judge the PSB 125 due to lack of online reviews. Can anyone help on this?

  • Kramer Crane from Crutchfield

    Posted on 4/5/2017

    Hi Bruce, a down-firing sub is your best bet in that location provided you don't have carpet underneath of it. If the floor is carpeted, I'd go with a front-firing sub pointed towards one side of the room or the other. I think a single sub is all you'll need for your system, though you can always gauge performance and add a second sub as needed.

    I highly recommend adding the Auralex SubDude underneath your sub. It made a substantial difference in sound performance in my system, and eliminated the vibrations of nearby windows and glass panels.

  • Bruce H from New Berlin, WI

    I only have one wife-approved location for my sub, fortunately in the front corner of the room behind the TV. Would there still be a benefit to placing two subs in the same approximate location? I primarily listen to music. Alternatively, would a down-firing sealed speaker be the better option, in concept, for this setup?

  • Kramer Crane from Crutchfield

    Posted on 2/10/2017

    Hi Tyler, the sub that you have from the HD Theater 1000 system is pretty solid for its size. I would suggest that instead of replacing it, you'd be better off adding a second sub to your system. In your price range, the Klipsch Reference R-10SW is an excellent choice to do that.

    Adding a second sub would give you more evenly distributed bass around the room. So not only would your system hit harder and be more impactful, but the quality of the bass would improve too. Sweet!

    Hi, I currently have a setup consisting of two Klipsch KF-28 speakers for my left and right, a KC-25 for the center, and for the surround and sub I'm using leftovers from my Klipsch HD Theater 1000 (so two of the satellite speakers and the 10 inch sub). I'm considering upgrading the subwoofer; how much of an improvement might I notice if I upgraded to something like the Klipsch R-10sw? It's hard to tell from the specs alone, but I'm just afraid that I'll end up spending around $300 and then not even notice an upgrade. Or maybe I should ask it this way: Considering the setup, if you were to upgrade the sub, what would you suggest as a noticeable improvement for the best value? Thanks

    I have a 10inch velodyne 100rms and im getting the sw112 with 300rms. I want to run both so i was going to leave the velodyne the way it is. Im just going to set up the sw112 by itself at first and when i get it the way i want it i was going to add the velodyne back in. I want the sw112 to do pretty much all the work so this is why i dont want to do a calibration with both subs. Guess its all about how it sounds to the listener but i just dont want to take away from the sw112. Thanks for any feed back.

  • Kramer Crane from Crutchfield

    Tye, many receivers have a "direct" mode that turns off the digital processing to give the speakers the cleanest power possible. Sometimes that can help with the quality of your bass.

    I've been extremely impressed by the ELAC Debut S12EQ. It has some cutting-edge room calibration (everything is done through your phone). It's an excellent option for hard-hitting bass that sounds great.

    The SVS SB-2000 is another great choice for room-filling bass.

  • Tye Frantz from hardesty

    Posted on 12/16/2016

    what do you mean by direct mode? my receiver does about every thing. do you mean listening in stereo setting only ? my sub is a polk 10 inch front firing, I wanna say its 150 watts, but I could be wrong, it is also around 15 yrs old give or take. what would be some some good replacement subs ? I want really hard hitting bass,, but I can't break the bank doing it , I would like to keep it under $1200 if I could

  • Kramer Crane from Crutchfield

    Joe, that shouldn't be any problem at all. In fact, having different firing directions may help improve bass dispersion in your room. It sounds like you're in for quite the treat!

  • Kramer Crane from Crutchfield

    Posted on 12/15/2016

    Hey Tye, depending on the wattage of your current sub, it may not be enough to really give you the low-end punch you're looking for. It sounds like a larger woofer with more amplification power is worth considering.

    If you haven't already, it's worth tinkering with your receiver's settings. Try direct mode when you're listening to music if your receiver has it. If you can adjust your subwoofer's output level through your receiver, that's worth a shot too.

    Feel free to give us a shout if you need some help on either front!

  • Kramer Crane from Crutchfield

    Posted on 7/29/2016

    Jordan, you raise an interesting question. My experience has been that adding a second sub is more about smoothing out room imbalances than it is closing any gaps that would exist in frequency reproduction. Since a 12" sub is going to cover virtually all of the LFE frequencies with authority, I believe you'll have a better system overall if you go with two 12" subs. Feel free to give us a call if you'd like any help choosing your subs. It sounds like you have a great system in the works!

    Posted on 7/24/2016

    What would provide a better listening experience? I've started shopping for 2 subs to put in my 7.2 setup. I keep seeing suggestions for using 2 of the same sub, if possible. I understand the reasoning behind it. My question however is: What about having a 15" sub paired with say a 10"? Would the 15" cover the lower bass the 10" can't get down to and, switched around, would the 10 cover the higher low stuff the 15 get up to? Am I thinking about that right or is a 2 12" setup the way to go at the end of the day?

  • Dave Bar from Crutchfield

    Posted on 5/25/2016

    Amos, My understanding from speaking with various subwoofer manufacturers is that you'll experience improved bass whether the subs are the same or not. Myself, I'm a "symmetry" kind of guy, and generally prefer using identical (or at least similar) subs when possible.

    Posted on 5/24/2016

    First - thanks for a very clear, good-for-the-layman explanation. You've helped a lot. second - in case of a 2-subwoofer situation, should I prefer the 2 subs to be as SIMILAR to each other in characteristics, or as DIFFERENT from each other? If it matters - I am mostly interested in music: classical and 50-years-ago jazz.

  • Dave Bar from Crutchfield

    Posted on 9/7/2015

    Jeff, In my experience the direction in which a subwoofer fires usually makes little if any difference. What will make a big difference is the use of two subs, versus one. A pair of subs will help iron out uneven bass response in a room, so you get better sound in more listening positions. They also provide greater headroom for more effortless output with less strain and distortion. Highly recommended.

    I have an open great room that is set up for 7.1/2. I have a 7.2 receiver. I ready to buy my sub, but I am concerned about where the builder pre-wired the outlet/coax for the sub. My TV is on the front wall, but my Sub's connector is on the left wall at the rear of the room. There is no back wall as it opens to the kitchen. I have looked at the Bic Acoustech PL-200, but it is front firing. Seems like I should have a down firing (onto carpet) or possibly trying to balance with an additional (non pre-wired) in the front of the room. The room is 16'X16' with two couches in an "L" shape. The connection is in the corner of the "L". No my wife won't let me move the furniture. :-) I have about 10' of open space from the TV wall to the couch and all speakers are recessed in the ceiling. Would love your thoughts. -Jeff

    Hi, Larry. You can definitely add a good subwoofer to your system for under $200. Check out these two customer favorites: Polk Audio PSW108 and Infinity Primus PS38. Just remember, a corner location will intensify the bass response, so you may need to turn the sub's volume down a bit to compensate.

  • Dave Bar from Crutchfield

    Posted on 8/14/2015

    Mel, Technically it may be possible to put your sub in that location, but I'd doubt it would do wonders for sound quality due to the boundary effects of being placed inside a piece of furniture. Also, I'd be somewhat concerned about what that much vibration might do to your TV. So I guess I'm saying that you could, but I'm not sure I would.
