That bass consistency, lol

I have 2 type s12s in a dual divided sealed box, wich means each sub has its own space in one box, and they slam with consistency I've had them for a time now and they still impress me, running on a 2500 watt power acoustic amp, wich I might add is a bad ass amp for the buck I've had two now and will run almost anything

Got this sub to replace a different sub in a existing sub box. The best sounding sub that I ever got. Alpine is top notch.

A weightier sub with great punch and slam than expected.

I bought the Alpine S-W12D4 to replace 2 Pioneer 10" shallow mount subs in my std cab older Ford truck. While the Pioneers were very clean and tight, they lacked heft in the bottom registers and my loud engine often drowned out the bass on the road. After much research considering my budget and space constraints, I tried the Alpine in a custom box of 3/4 MDF in both ported and sealed versions, behind the bench seat ultimately settling on the sealed box. The ported box hit very hard at the lowest octaves but wasn't as clean nor as dynamic as I desired. The sealed box wasn't nearly as strong down low, but was very smooth, punchy, controlled and never ran out of steam. I have a modest system with a 3 way component for the front end through a 700w 5 channel amp with 350 watts to the Alpine at 2ohms. This sub, fresh out of the box easily over powers the mids and highs except when I'm driving with a lead foot. When the engine is off, the bass has to be turned down, but cruising it brings a smile to my face. It has enhanced my musical experiences over the previous dual 10" set-up in all aspects. I have played with crossover points a lot and it plays well, in my truck, to 100hz with no troubles and it actually has very good mid bass qualities for a 12" sub, but obviously, that is not its forte. IF you are looking for a modest but punchy and strong sub you should check this one out.

Buy ASAP

I am running two of these on a JL Audio 1000 watt amp in a ported box. Facing the trunk in my 14 Passat TDI BANGING REDICULOUS!!!! Hard to describe how perfect every bass hit is in the vehicle. Really clean sound when I play rap or rock.

This sub sounds amazing!!! I have always been a fan of Alpine, but this is the first Alpine sub that I have owned. Not sure what took me so long... I plan to buy another one soon. The shopping experience was nothing less than great. You will not be disappointed with this sub. Just a great quality sub!

Slammin'!!!!!

I started out with a chat session advising the tech on specs for a box I already had. He advised that these would be a perfect fit for what I was looking for and he was right. These speakers are awesome!!!! I listen to mostly rock and it delivers!!!!

Everything I expected

I used these to repower some 10 year old Definitive Technology BP-8080 home speakers that originally had built in subwoofers with dual passive radiators, one built in sub fried and one OEM amp quit. Replaced both subs with 2 of these and powered with a Crown 2002 amp, VERY pleased with the sound, they absolutely pound if wanted. Wired at 2 OHMS with 1000w rms to each and couldn't be happier. *be careful, they're only rated at 600w rms."

Excellent built

After failing with skar audio and Pioneer which burned after the 1st week of use. I found this true 600 watt rms subwoofer performance flawlessly. Never used alpine until now. Very satisfied with the subwoofer very well built and handles every watt as it should. Crutchfield has awesome shipping very fast only took 4 days to get my items to Alaska. Highly recommend Crutchfield will be buying again.

Sounds great. Have it paired with a Pioneer 5 channel pushing 600rms at 2ohm. The musicality is excellent which is what I was looking for. Its not the loudest woofer I've ever owned, but it makes for a great addition to this setup.

Exceeds expectations

I just installed a pair of these in my 14 Impreza. Mounted in a SKAR sk2x12v ported enclosure. Wired in a 1 OHM configuration, 800 watt Rockford Punch. Incredible sound, doesn't sound too "boomy", great depth, hits much harder, and more clearly than the Ultimax they replaced. I listen to all types of music, but primarily metal. I am very satisfied with the response of these subs. The double bass is crisp and clear, and bass drops, or when I listen to hip hop, plenty of low end. The only downside? I had to replace my license plate bracket. Still breaking them in, but I imagine they will sound better and better.

This thing hits just as hard as the typr R in my opinion. Be sure to get the right spec ported box and this thing knocks. 500 watt alpine amp is perfect pair. Same price as the kicker Comp R and having both now what a difference the alpine is.

this sub sounds amazing, handles the volume well, and puts out what i feel to be a very tight bass response to that very close to replicating true bass, and other low ends

Blew the Voice Coil Under Minimal Power in Less Than 3 Weeks

This product is a pile of trash. I had it hooked up to an Alpine MRP-M1000 and had the gain turned all the way down. I only used it for about 3 weeks before the coils started smoking and in no time they uncoiled. Let this be a warning to future customers. Don't buy.

Hooked this all up.. An hour later my trunk was smoking... Something had happened and all the voice coils unwrapped on the inside.. I truly believe this speaker i got was defective.. $$$ down the drain ??
