Maximize bass performance in tight spaces with a recessed suspension that allows full cone excursion within the frame, needing just 0.87" of frontal clearance. Engineered for small enclosures, its shallow mounting depth and high excursion capability deliver smooth, powerful bass from compact boxes. The injection-molded, mica-filled polypropylene cone with rubber surround ensures long-lasting durability, moisture resistance, and minimal distortion for crisp, clean sound.
Enjoy tight, clean, and powerful bass at any volume with DMA-optimized design—featuring proprietary motor, suspension, and cone modeling for perfectly linear excursion. The cast-alloy, space-saving frame with flat edges allows multiple subwoofers to be installed side by side, maximizing performance without taking up extra space.
Engineered for adaptability, this subwoofer delivers powerful bass in both sealed and ported enclosures, supporting amplifiers from 75–300 W RMS. Its compact 4-5/8" mounting depth makes installation in tight spaces effortless, while the innovative concentric tube suspension design minimizes profile without sacrificing performance—bringing big, clean bass from a small package.

impressive sound. for the size, power, and price, the sound is amazing. it sounds clean and you can feel the bass. runnin' with a 500-watt amp for more than years, and it still sounds great. sturdy, solid little sub. this thing packs a nice punch. not that expensive, either.
The sub’s shallow design helps me to make my enclosure much smaller, which means that it takes less space inside my car. When it comes to its sound quality, its just like you’re having an 18-inch sub with how it hits hard. Powered with an Alpine amp, I’m pretty satisfied with my setup now.
