About the Digital Drive Plus 18
The Velodyne Acoustics Digital Drive Plus 18 (DD-18+) is a high-end sealed active subwoofer using an 18-inch forward-firing fiberglass Rohacell laminate cone driver with a six-layer 3-inch voice coil and a massive magnet structure, engineered for very low distortion and high output. It is powered by a 1250W RMS / 3000W dynamic Class D amplifier and employs Velodyne's Digital Drive Plus DSP and high-gain servo control sampling the driver response 16,000 times per second to minimize distortion and improve linearity. The DD-18+ offers automatic room EQ with measurement microphone plus manual multi-band parametric EQ via PC software and USB connection, allowing precise tuning of low-frequency response to the room. Connectivity includes unbalanced RCA, balanced XLR and mini-XLR inputs, LFE input, and RCA/XLR outputs. Designed for audiophile and home cinema applications, it provides deep bass extension to approximately 14Hz with high output, very low distortion under 0.5% THD, and excellent pitch definition.
