Extreme Bass

It's simple, I am the envy of my friends eyes and ears. I truly dominate the sound system battle at my school.

Great Sound

I haven't owned any of these new Type S subs by Alpine yet, but they do have them in my local store. They had it powered on an Alpine 1000 watt amp and the box they used was ported. Sounded pretty decent for 15s, but could probably sound better in a sealed box. I would recommend these to those who love Alpine quality and speaker/subs.

Sounds good to me

Had this sub for about three months. Shipped from sonic. Break in period was a breeze. It handled every bit of 500-700 watts without a hiccup and sounded pretty decent in the trunk of my car in a 2.6 cube groundshaker enclosure. Had the right about of boom with Rap and punched like a sealed with Rock and handled all the dubstep I threw at it without skipping a beat. Alpine defiantly has a unique sound that I certainly approve of. Good sounding product for the money. I would say buy if this sub in this price range if it appeals to you. Should be no disappointment.

Amazing for the price

I purchased on of these a few months back and it slams. powering it on an Alpine MRX-M55 at 2 ohms, 550 watt rms in a ported box to 32hz. it sounds amazing and hits harder than anything I've owned before. You can't go wrong with this sub.

Best sub ever

I have had the type r 15 and this one sounds waaaaaay better. Alpine is the best period. I have one running at 500 rms and I can't use any mirrors at all. My rear deck by 6x9's does the wave. It's in a 2 cu ft sealed box and loves it! Love you alpine and sonic!
