About the DD-12+
The Velodyne DD-12+ is a sealed, forward-firing 12-inch subwoofer from the Digital Drive Plus series, designed for high-end music and home cinema systems. Powered by a 1250W RMS / 3000W dynamic Class D amplifier, it delivers deep bass extension down to approximately 17Hz (-3dB) with very low distortion.

The DD-12+ incorporates Auto-EQ Plus room correction using a supplied calibrated microphone, and allows detailed manual EQ via computer connection. Connectivity includes LFE and stereo line-level inputs (RCA and balanced XLR), speaker-level inputs, and line-level outputs for flexible system integration. Available in black gloss ebony, satin cherry, and walnut finishes.
