Technical Details
Velodyne's DD-12 powered subwoofer has a built-in 'Class D' amplifier that provides a staggering 1,250 watts RMS and 3,000 watts peak power. The 12" forward firing Kevlar-reinforced resin driver has a 9.7" piston diameter, 3" push-pull tandem voice coil, and 19.3 lb. magnet structure. The DD-12 includes Velodyne's revolutionary Digital Drive room management software that works with the included microphone to optimize performance for any room position. Inputs include RCA and XLR LFE, line-level RCA, and speaker level binding posts. A full-featured wireless remote comes standard. Digital Drive DSP-based subwoofers are the finest subwoofers ever made by Velodyne. And that's saying a lot. They embody all of Velodyne's industry-leading knowledge and experience in low frequency technology. Velodyne pioneered the use of Digital Signal Processing (DSP) for subwoofers. This technology provides incredibly accurate, reliable, and feature-laden performance. The software that runs Digital Drive subwoofers was 100 percent custom written by Velodyne engineers for the best possible sound quality. Digital Drive-Series subs feature Velodyne's revolutionary Digital Drive room management software that takes subwoofer room equalization to an unprecedented level. The built-in Real Time Analyzer (RTA) allows the subwoofer's frequency response to be measured using a calibrated microphone and viewed graphically on any standard TV. The onboard digital toolset, which includes a graphic equalizer, is used to optimize performance for any room position and to perfectly blend the subwoofer with the main speakers. All Digital Drive-Series subs come preprogrammed with six listening mode presets for Action Adventure Movies, Rock/Pop, Jazz/Classical, a custom preset, and EQ defeat. Each preset also has a "theater/music" setting that allows the sub to play louder (for movies) or tighter (for music) depending on the source content.
