The Velodyne Story . . .

Founded in 1983 by David Hall,

Velodyne Acoustics is the result of an

effort to bring the discipline of me-

chanical engineering and the doctrine of common sense to the field of high performance audio- the Silicon Valley approach to sound.

Through innovative thinking and inventive design, the company pio- neered the first true servo-controlled subwoofers. The result was both the reference standard for bass repro- duction and the foundation for distor- tion-free listening.

Rejecting the trend toward high-end indulgence or fancy marketing gim- micks with no relevance to improving sound, Velodyne devoted its techni- cal resources to bringing the benefits of ultra-low distortion technology within the reach of all dedicated music lovers. In fact, many state of the art recording studios & homes now feature Velodyne subwoofers as their "reference standard" by which all others should be judged.

With the introduction of Velodyne's Distortion Free Series for the automo- bile, listeners finally have access to all the details and dynamics that make up the modern listening experi- ence. Anything imperfect originates elsewhere. By design, Velodyne speakers are incapable of error.

to the amplifier. Forcing the speaker's acoustical output into a true representation of the music.

The term "servo" is misused by some manufacturers who use a different motor on their speakers to try and make woofers sound like larger more powerful units. Unfortunately this usually results in a large amount of distortion as well. At Velodyne, we take an already large & powerful speaker, then use motional feedback to create a true "servo" controlled speaker. This reduces distorion and achieves a level of sound quality never before heard of.
