The Distortion Limiting System (DLS) subwoofers consists of three models: the DLS-3500 with an 8 driver and 160 watt RMS/350 watt dynamic power amplifier, the DLS-3750 with a 10 driver and 175 watt RMS/375 watt dynamic power amplifier, and the DLS-4000 with a 12 driver and 200 watt RMS/400 watt dynamic power amplifier. The key feature of the DLS series is Velodynes exclusive Distortion Limiting System technology that significantly improves the subwoofers performance by limiting audible amplifier distortion and controlling the driver excursion. The result is subwoofers that reproduce music and home theater with a fraction of the audible distortion found in competitive products. This exclusive DLS technology increases the detail and definition of these new subwoofers without sacrificing output or dynamic impact. Minimize
