DESC: The Distortion Limiting System is the touchstone of this subwoofer series. DLS significantly improves these subwoofers performance by limiting audible amplifier distortion and controlling the driver excursion. This results in real performance advantages, including: significantly more usable power, deeper bass extension, bigger impact, and most importantly, less distortion. Utilizing this technology, the DLS subwoofers reproduce music and home theater with a fraction of the audible distortion found in competitive products without sacrificing output or dynamics.
