Since 1983, when Velodyne revolutionized the subwoofer category with its patented High Gain Servo technology, reviewers and consumers have acknowledged the accuracy and musicality of Velodyne's ULD and F-Series of subwoofers. However, for many customers integrating these large subwoofers into their home was difficult. Now, Velodyne's engineers have updated their servo-controlled system, linked it to unique "Dual Tandem" voice coil speakers driven by a Class D patent pending amplifier that delivers more than 3000 watts of peak power, and packaged them in ultra-small, elegant black gloss cabinets. The result is powerful, low distortion bass from a very little box.
