Velodyne Acoustics SubContractor Series
Performance. Nothing else.
No compromises: Built directly into the wall, these bass wonders remain completely invisible despite their impressive performance. Thanks to their inconspicuous wall installation, subwoofers from the SubContractor series are visually unobtrusive and provide optimum acoustic working conditions. The uncompromising solution for professionals.
Velodyne Acoustics SC-IW and SC-1500
With its two-part closed housing and the newly developed T-shaped bass drivers, the SC-IW achieves an impressively deep and precise bass response without causing the wall to vibrate. The housing disappears completely into the wall except for a narrow sound outlet opening.

The two 6.5-inch long excursion drivers work together with two passive diaphragms and achieve a total diaphragm area of a generous 14 inches. The SC-600D system amplifier delivers 400 watts of impulse power.
