GOOD PRODUCT

The following review is for CTM, which is a part of the bundle you are viewing.

Super thick and easy to install. Noticeable difference and reasonably priced. 5 stars

What a difference

The following review is for CTM, which is a part of the bundle you are viewing.

I came across this while looking for something to get rid of the rattle in my trunk. I bought it and when I opened my package, immediately knew it was of good quality. its thick and stuck well wherever I placed it and it made a noticeable difference. The rattling is gone and my JL Audio W3 sounds much deeper and louder. Thanks Sonic!

Alpine's Top of the Line

The following review is for SWX-1243D, which is a part of the bundle you are viewing.

I've had this subwoofer for about 3 weeks now and I must say that this is a great subwoofer. I've only owned a few speakers in my life and this is the best one. I replaced an Alpine Type-R in a ported box with this Type-X in a sealed box and I got the best of both worlds. The Type-R was loud but the sound quality lacked because at higher volumes, transitions between bass notes were slurred. The Type-X in a sealed box gave me the sound quality I was looking for, each bass note is very cleared and crisp, and the lows are unbelievable. I also got the loudness of the Type-R with it. Best of both worlds in my opinion. Now don't get me wrong, the Type-R was louder, but if you're looking for a sound quality oriented subwoofer, loudness is not the first thing to look for, however, the Type-X does get loud. Overall, this will probably be the last subwoofer I buy, and if I do buy another, it'll be a second Type-X. For the price, you can't beat this subwoofer. Period.

Great sub

The following review is for SWX-1243D, which is a part of the bundle you are viewing.

Terrific As Always

The following review is for SWX-1243D, which is a part of the bundle you are viewing.

As a returning customer, it doesn't surprise me that my sub was shipped with care and on time. The prices that sonic offers are also the best you will find. Now the sub, I replaced my Alpine Type R 12 (also purchased from here) with this 12 inch Type X and the difference in both sound quality and projection is amazing. I have never been let down by any products made by Alpine. The Type R sounded really good, but this Type X in a custom made ported box sounds awesome. The kind of bass you can really feel in and out of my truck, and the gain on my alpine Mrx-m100 is turned only halfway up. Once again thanks for the great service.

GEEEZZZZ

The following review is for SWX-1243D, which is a part of the bundle you are viewing.

I just hooked one of these up in my 01 prelude at a 2ohm load running about 2000 to it and it freaking slams...I was just used to my Rockford p3 at 800 watts...This sub is very loud..my favorite sub I have owned so far... I have had SWS's and SWR's and my Rockford p3 and I had a w7 that got stolen and I still like the type x way better than the w7. And I paid twice the amount for the w7...
