Velodyne Previews The World's First Digital Subwoofers

23-Dec-02

Velodyne Acoustics, Inc. announces the introduction of a revolutionary approach to the design of high-performance subwoofers. The Digital Drive Series subwoofers are the industry's first all-digital, high-gain servo-controlled subwoofers. Featuring new 18-, 15-, 12-, and 10-inch custom-designed drivers, andpowered by Velodyne's patented 1250 watt RMS ""ERS"" switching amplifiers, these standard-setting subwoofers are also the first to incorporate Velodyne's patent-pending ""Digital Driveô"" system.The Digital Drive Series features Velodyne's new, revolutionary ""Digital Driveô"" technology that takes subwoofer room equalization to a new level. This latest Velodyne innovation allows the subwoofer's frequency response in any room to be measured using a calibrated microphone, digitally corrected, andstored in the unit's memory to assure ideal performance in the consumer's listening area. This is accomplished with an on-screen graph of the system's actual frequency response, and on-screen feedback as the user makes digital adjustments to subwoofer equalization, phase, and crossovers. The consumer or custom installer can also modify additional overlaid curves to realize optimumperformance for various source materials such as action/adventure movies, rock, pop, jazz, or classical music, or through custom settings to match the consumer's taste.The Digital Drive Series subwoofer also incorporates Velodyne's patent-pending Digital High Gain Servoô technology that uses Velodyne's proprietary sealed digital accelerometer that measures cone movements 10,000 times per second in order to correct for any distortion. The results are subwoofers with over 3,000 watts of dynamic power that deliver clean, accurate, high-impact sound, from 15 to 120 Hz with total harmonic distortion below 0.5%.The Kevlar-reinforced drivers designed for the Digital Drive Series incorporate Velodyne's unique 3-inch Dual Tandem Voice Coil Design that delivers extremely high power handling, linear travel, and low distortion. Velodyne President David Hall notes, ""These drivers generate less than half the distortion of conventional motor designs, and are capable of four times the heat dissipation.""These subs feature incredibly light, stiff, low-resonance Kevlar-reinforced cones, custom-designed variable thickness EPDM surrounds, and unique new die-cast aluminum baskets.The Digital Drive Series subwoofer is scheduled to be available for audition and purchase through Velodyne's authorized dealer network in the second quarter of 2003. Due to the sophistication of this product, it will not available through mail order or on the Internet. The retail pricing of the Digital Drive Series has not yet been finalized.For more information on the complete range of Velodyne products, visit www.velodyne.com.
