Intelligent Digital Amplifier

DSW Series subwoofers use intelligent digital amplifiers. This means, not only can they put gobs of power to your woofer, they'll use very little power at low volumes or standby mode.

Feed Forward Anti-Distortion Technology

Turn any speaker or subwoofer too loud and it'll distort. Instead of using an unintelligent, performance limiting "brick wall" limiter or an antiquated servo feedback system that reduces distortion after it's already occurred, Feed Forward addresses distortion head-on before it happens while maximizing bass response. The result is bulletproof reliability with ultra-pure performance. Click here for a technical explanation.
