Audio/Video Subwoofer System

Printed on recycled paper.

“Not only was the little Velodyne the best small sub I’ve ever used, it was

one of the very best subs I’ve used.”

-John Potis
SoundStage!, April 2002

“The SPL-1200 was able to hit an impressively deep 16 Hz”.

-Tom Noussaine
Sound & Vision, June 2001

“How do they get this kind of bass out of such a tiny box?  Deep, tight, tuneful
and loud enough to rattle pictures on the wall—this is serious subwoofing.”

-Robert Deutsch
Stereophile Guide to Home Theater, September 1998
