Alpine SWX-1243D

Alpine's Top of the Line

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

Amazing sub, hits way better than my old type r and the sq is awesome. Great shipping from sonic for sure.

Terrific As Always

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.

Boom Boom Bass

If you bass in ya face then this is for you. Boom Boom, Boom Boom, Boom Boom.

Great sub!!

man i love this sub!!!! i just have one in my car powered by the power acoustik A3000DB and it hits!!!!

GEEEZZZZ

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...

love it!!!!

Love this sub. Sounds great and for the price it can't be beat. I have it in a 2.0 cubic feet box and it vibrates my whole truck. Thinking of getting another one!!!

Excellent subwoofer!

These subs are amazing. I have them fully powered and they are by far the loudest subs in my area. Also, these subs put out very clean-tight bass. I would highly recommend these subs to a friend. I pound these subs all the time and they haven't skipped a beat.

gods gift for a perfect system

I own 1 of these and hooked it up to my jbl amp which is 1000 watts rms at 2 ohms. this is exceptional because the type x sub is also 1000 watts rms at 2 ohms. I have it in my 2005 mustang gt and i feel like either my brain will melt or my throat will vibrate to pieces. this sub is so clear and so hard hitting it is ridiculous. the low bass is so deep it is unbelievable. i have it in a 2 cubic foot box and it is at 155 db don't believe me well buy one and prove me wrong. this 1 12 inch sub hits harder and is louder then my previous 2 15 inch subs combine. my grandfather was in his house 1/4 mile away with the air conditioner on and a radio playing and still he could feel and hear the 12 inch type x subwoofer bumping the country. yes i said country music. when i play hip hop music such as the song "a millie" well forget about it i might as well take my trunk and rip it off lol. will my warranty for the sub cover my trunk haha. I definitely give this sub a perfect score. BUY THIS SUB ASAP AND BE AMAZED.

Awesome Bass!

I have two 12" Type-X subs ported hooked up with an M-2000. Front type-R component system and 6x9's in the back hooked up with a PDX-400. All Alpine with an Alpine deck. Stinger cables, upgraded alternator and with two upgraded batteries. System bumps for two subs I am pleased. My amp isn't even all the way up. I know people hate on Alpine but I am satisfied. The price on this site are pretty legit because Alpine employee discounts are about the same rate.
