Quality soundbar

The Polk soundbar has great sound for my living room. I use it for both the tv and also to play music via the Bluetooth connection. I'm also impressed by the HDMI arc connection. Sound options available for the source playing is also a plus. It's a quality system for the price.

Bad driver.

The overall sound when power up was distorted at low frequency. Found one of the front speaker defective ( picture). Remove the driver and now sound is good. Maybe was a situation during shipping or manufacture problem. The wireless subwoofer work perfect.

They look nice!

When they work they are good, but sometimes they disconnect. Sometimes they reconnect themselves, sometimes they don't. Then I have to reboot (ac plug) then they work again until they stop. My previous sound bar (different brand) purchased as a refurb from Crutchfield did the same until it stopped altogether so I tossed it. Most likely my tv resides in an evil vortex which causes the problem!

It's "ok". Certainly not a Bose quality, but ok for the price point.

I got this setup for the price and good reviews. However, I was very disappointed. I currently have an inexpensive big box store soundbar and subwoofer that I wanted to upgrade. This Polk setup was weak and only one step above TV sound. The soundbar frequently lost connection with the subwoofer and was all together just.weak.

Easy as pie.

Can't tell you how much I love my Polk Signa 4. It certainly enhances our audio on our tv. No buyers remorse here. I couldn't believe the cars happier and it was a breeze setting up.

Works well. Does not display volume level on TV screen which is disappointing. I wear hearing aides and like a volume indicator displayed so I have a baseline. But overall, it's a good system.

Great sound from an easy to set-up system

Wasn't sure exactly what I wanted and wanted to stay within a reasonable budget. Sonny at Crutchfield walked me through several options and answered my questions to help vector me to this system. The Signa S4 doesn't disappoint. The S4 had a wide frequency range for my ears and noticeably enhanced the sound from my TV. Highly recommended for great sound and great value.

Excellent value

Excellent sound bar at the price point for TV and movies. I especially appreciate the clear dialogue and dialogue enhancement options. All remotes should be like this one; simple, intuitive and highly functional, it controls dialogue enhancement levels, subwoofer level, listening mode (movie, night, music). The wireless sub is attractive and connects easily. Highly recommended for a budget/mid level sounder for clear dialogue and ease of use. My one gripe is with the sound quality for music via bluetooth - a big disappointment - sounds muffled, distant, and lacking any dynamics, even in music mode. If you aren't going to use the bar for music, or just using for background music, this a great value.

$ 299 well spent

It's a beautiful thing when your New product operates just as advertised and more. It makes my little room seem bigger than it is. And it's clean and punchy when needed. I'm really enjoying my S4 And I would suggest it to anyone that has a tight budget like mine. Outstanding ????. Polk

Crutchfield response on

Great with a caution

Ok, the sound is exceptional... EXCEPT that you really can't put the sub just anywhere. We've experienced exceptional reverb or bass tonal delay when the sub is placed behind something. Placing the sub as close as possible to the soundbar seems to solve this. It's more evident with deep male voices who may have their tonal range split across the soundbar speakers and subwoofer. Otherwise the Atmos is great and it really does have room-filling sound.

Have only been using the Signa S4 a little over a week, but very satisfied so far. Great sound at a reasonable price, and once again Crutchfield delivered on time and a well packaged product! Will definitely continue to purchase from Crutchfield!

Polk Audio Signa S4

This sound bar works great. My wife and I have a hard time hearing the dialog when watching tv. We are both in our 70s. This sound bar makes it so much easer to listen to the dialog. The only thing that I didn't see in the instructions was how to get the sound bar tower on a Vizio. You have to go to settings and select audio, then click on AUTO speakers. After you do that it will connect to your tv and you can make adjustments. Great system.

Excellent Soundbar- Superb Value

This is a very nice soundbar. We bought a 65" tv that has poor sound so we needed a soundbar just to make dialogue audible. The Signa S4 reproduces dialogue beautifully. Our room is 30' X 45' and the S4 fills it with sound. The Night Mode works great, keeping dialogue clear and taming the big sound of the soundbar and sub. Setup was simple, just hooking up three cables, plugging in the soundbar and subwoofer, and putting batteries in the remote. The most difficult part of unboxing and setup was unwrapping the batteries for the remote; I kid you not. The soundbar Bluetooth-paired with my iPad easily and sounds good playing music. In my opinion this soundbar is an excellent value and I bought it on Weekly Special which makes it a ridiculous value. Watch those Weekly Specials folks.

Buy This!

I am using this in my back "music room" to listen to songs recorded using Dolby Atmos, for the most part. The sound is amazing so far, incredibly easy to connect the system. For the price, I am extremely happy.

Nice system

Replaced an old Polk SoundBAR (original!) and PSW10 sub. Very happy - great sound and we really like the dialog enhancement. The old soundbar/sub required a pre-amp, it's convenient that this doesn't although the new sub doesn't have quite the power of the PSW10.

Signa S4 Delivers - 5 STARS!

The Polk Sign S4 soundbar is the clear winner in overall design, sound, and ease of setup. The Voice Assist feature is amazingly accurate at defining center channel spoken dialogue. The Bluetooth lets anyone effortless stream music from a phone to the soundbar. The Dolby Atmos is absolutely mind-blowing, and this bar can fill an entire room with incredible sound. Polk has always been my choice for outstanding audio designed by experts in the field of sound technology. Signa S4 is a clear 5-STAR winner!

Similar to other reviews. When I volume up/down with my Xfinity remote, it skips a level or two. Using the remote with the S4 works better. Setup was easy using HDMI (eARC). Sounds really good.

Polk Audio Signa S4

The sound has been great. Our TV is an older Toshiba and it only has 3 HDMI slots which are used for other device connections, so we are using the provided optical cable. I think that may be the reason we have echoing occurring with the TV's speakers and the sound bar. I haven't had a chance to play with this other than muting the TV speakers so that we only have the sound bar in use.

Great sound at a great price

This is a great sound bar. The dialog is clear and the bass is enough to be effective. The wireless sub is great, you can put it anywhere in the room. I have it in a small room and it sounds great. Also very easy to set up. The settings are few and simple, but they work well.

The sound bar and sub system really stepped up our television audio. Television dialog is much clearer and audible at a lower volume level. Movie audio greatly improved. Really like the separate bass control on remote. On/off and volume work through existing cable remote. Installation was very simple. Very pleased with this system.

Very nice sounding sound bar, sounds better the more you use it. Dolby Atmos sounds nice but could be more pronounced, but overall worth every penny. Very simple to setup out of the box. But for the price, you can't beat it IMO.

No good sound quality

For the price point this sound bar does not meet expectations. They quality of sound is not crisp compared to the Sony A80J. Technical issue I would turn off my TV but the audio wouldn't turn on. I would have to go to audio settings change to TV speakers then switch back to external speakers. Contacted Polk never got a response back. I'm returning this back. If they would like to help me let's try again by delivering a new soundbar with extra speakers to put around the house. I also contacted the other retailer no response to exchange hdmi 8K cable to see if that was the issue. No real help from, but only Crutchfield who are outstanding and attentive.

Signa S4 - Big Step-

Got the S4 to improve the sound on my new 50" Samsung 8000 Series TV. Big improvement over the Samsung stock speakers! The Quick Start manual included with the S4 could have used a few more details. Voice sync on initial setup was poor, but that turned out to be a problem with the TV "Expert Settings". Once I adjusted the "Audio Output Delay" setting, everything was fine. I recommend using HDMI-ARC connection if you can. Don't expect this to sound as good as the IMAX Theater speakers! Signa S4 is a $300 soundbar, not a $1000+ unit.

My 86 year old mom loves it!

I purchased this soundbar for my mom. After a very easy set up and watching a few shows, she gave it 2 thumbs up. The voice + button option is really nice. Works well. Music button option makes music sound decent for a soundbar output. The only con for me (And it's a small one.) is the size of the subwoofer.

Solid purchase

PROS: easy connectivity, Subwoofer is wireless so can be moved around to find the sweet spot., audio quality is good when up mixing audio, excels with 5.1, atmos sources (if connecting from game console or STB, make sure sound is set to 'bitstream out', and tv settings need to be set to dolby digital (via ARC hdmi port) for 5.1 and dolby digital+ for atmos. If you have an eARC port on your tv, even better as its loss less.)., Height channels really shine despite having vaulted ceilings and not 7'-12' flat ceilings. To judge audio quality perfectly, you need an ideal room (ceiling, material of ceiling, wall, size, distance from bouncing sounds, etc.) so it's hard to pinpoint exactly how good this soundbar can be. CONS: comes with limited instructions, lack of features. Bottom line: if you're looking for a solid soundbar for good surround sound, and dont care about bells and whistles, you cant go wrong. I give it a 4/5.
