Alpine SWR-1242D 12" Type R Subwoofer

Loud. Clean. Long.
Alpine Type-R subwoofers play loud, clean, and long. The Type-Rs are designed from HAMR Engineering, Alpine's exclusive subwoofer solution for cooler operation, longer life, and tight, accurate bass. The main philosophy behind HAMR Engineering is to ensure the ultimate sound quality and performance through the use of highly advanced materials and patented design technologies such as magnetic, structural finite element analysis, and a 3rd generation CRC motor structure. The Type-R subwoofer features an ultra long linear excursion for dynamic, realistic sound. Exclusive cooling technologies contribute to huge power handling capabilities. You can depend on the Type-R to compliment your system with deep, accurate bass.

Alpine is IMO the best there is in car audio. I've tried plenty and always found theirs to be the best. This speaker takes the bass and really pounds with all music. Best is it doesn't fart out at high volume like a lot of others. Beats the crap out of rockford fosgate.

I have a ten inch type s in a closed truck box amped to roughly a thousand watts and this sub pounds for a ten. Granted a wrangler is a relatively small space but it definately turns some heads. I traded my two twelve inch type e alpines for this sub in the box and an alpine350 watt amp but did not fuel ten with enough power. Great noise for the cost

Value for money and delivers the bass. Well suited for both ported and sealed box. Running mine on an Alpine V12 MRV 1505 bridged (twin subs) and its loud when cranked up to the point of getting a headache.

I have the 10" version of these speakers, the one issue i have with these is i wish that i got the 12's. These are awesome speakers though, and for the size are more easily fit.

This sub does everything I need it to do and so much more. I find myself having to turn my bass down a lot because it is so loud. I love my Type R's!

The aplhine line of audio components are in my opinion very high in quality relative to its price. Their subwoofers has a very clean sound. If you prefer quality over volume I would strongly recommend this product

I paired this sub with a 12" sealed box and a RF-1000D monoblock amp. The audio is clean, and I've never had the audio clip once.
