For sale by original owner; older Velodyne Foundation Series Servo Subwoofer F-1500-B - in excellent condition.
The Velodyne F-Series Servo Subwoofer F-1500 is a high-performance powered subwoofer known for its groundbreaking use of an accelerometer-based servo feedback system to significantly reduce distortion and improve bass accuracy. The Velodyne F-1500 is a highly regarded piece of audio equipment, often praised for its ability to deliver powerful, deep, and highly controlled bass that performs well for both music and home theater. The servo system significantly lowers distortion levels, typically to less than one percent; a revolutionary achievement at the time of its release which remains a key selling point today for audiophiles who prioritize musical accuracy.
Key features of the Velodyne F-1500 include:
The Patented Servo Technology featuring an accelerometer (a 2.5-gram sensor) attached to the voice coil, which constantly measures the cone's movement. This information is fed back to the built-in amplifier 3,500 times per second, allowing the amplifier to correct any non-linearities and distortions in real time, resulting in exceptionally clean and tight bass, even at high output levels.
A massive, front-facing 15-inch driver with 96 oz magnet to move significant amounts of air for deep, impactful bass extension, to below 19 Hz; within a substantial 20" cube enclosure weighing 79-pounds to handle high output without cabinet resonance.
Crossover Control featuring both a fixed 85 Hz passive high-pass filter for the main speakers and an active variable low-pass filter (ranging from 40 Hz to 100 Hz) to precisely match the subwoofer's output with the main speakers.
