New and Improved Alpine Type-R:

This fourth-generation Type-R subwoofer features the cleanest sound with the most efficient force control. With updated assembly, this subwoofer is able to withstand higher temperatures more efficiently without distortion. This new structure greatly improves installation options by allowing a shallower mounting depth. Delivering the best bass output, the Alpine SWR-1223D has been redesigned to enhance audio playback and become your ideal sound system. Type-R's new depth design offers a 20% reduction while adding the new and improved magnet structure. With this updated double-stacked strontium magnet, this product gains over 20% more motor force to provide a louder, cleaner bass. The optimized CRC machined motor creates an even magnetic field to provide the user with less distortion and overall improves the subwoofers power handling. This subwoofer features a High-Amplitude Multi Roll (HAMR) to provide excellent excursion with overall better output. Having a new and improved airflow management system controlling the temperature of the voice coils, the air is redirected across the heatsink to avoid overheating. With heavy playing time, this heatsink feature minimizes the amount of compression to reduce any heat damage to the voice coils giving you a long-lasting subwoofer.

Great!

These things have some power. No doubt the best I've heard. The neighbors get so mad, even people driving next to me. I have mine wired at 2 ohms hooked to a power acoustik 3000 watt amp. I'm sure the amp isn't pushing 3000 watts all the time, but the subs still get insane power, and have great power handling.

hits hard and is durable

I have two in a ported box running at 400watts each. Wired to 2 ohms. They slam. They don't have much distortion. I got them 6 months ago and held up great. I got an alpine 15 type-r and need to install it. All I have is Alpine in my car. Also 4 spr-60c component speakers from alpine. I'm running them at 50 watts each and they're great. I'm going to run them at 100 watts each soon since they're rated 110 rms. Anyway alpine is awesome and the way to go. With just those 2 swr 1223d's I've gotten pulled over for shaking a cop's windows while I was at a red light and he was over in a parkinglot about a block away.

The things rock

They kick ass. Plain and simple. They're not too pushy, they're there when you need 'em, and they continue to blow my mind when I least expect it. If you're considering doing it, do it, you'll be glad you did.

Awesome subs

After about 6 months of deciding... i buckled and got the Alpine Type R. Always heard good things about them and decided to get a set. FIrst off these things are monsters. They already sound better then my P2's and hit harder and deeper. Very pleased with my purchase and can't wait to hear them when they are broken in.
