Velodyne DD-18+

The 18 inch Digital Drive Plus is the pinnacle of almost three decades of Velodyne subwoofer engineering expertise. Velodyne's exclusive patented accelerometer based High Gain Servo System whittles its distortion down to .5%. 

Its cutting-edge, highly sophisticated, 8-band Auto-EQ+ technology assures not just low distortion but the most accurate bass available from any subwoofer available in the market today. Quite simply, the DD-18+ is the biggest, baddest, cleanest, hardest-hitting sub in the world today. It is capable of a staggering amount of output; at 115 dB maximum, it’s 5 dB louder than a sonic boom. 

Needless to say, it also gets low—way, way low, with a frequency response between 14.4 and 120 Hz at 3dB down. You can calibrate the subwoofer’s response automatically or manually with the 8 band parametric equalizer with on-screen graphics, or computer readout using the front mounted USB port. 

You can even adjust the degree of control by the digital servo. The DD-18+ perfectly meshes audio engineering with the art of design to deliver a frequency response between 14.6 and 120 Hz, with a huge 1250 Watts RMS, 3000 Watts Dynamic, power amplifier, reproducing even the most challenging audio for applications from music to home theater to gaming.

Unleash the authoritative power of the 18 inch Digital Drive Plus on your largest listening spaces and sink into the aural experience of over 99.5% accurate bass reproduction with unbelievable muscle, perfectly optimized by the 8-band Auto-EQ+ equalizer feature and remote-controlled presets to ensure you get the most out of your new audio equipment.
