Velodyne SPL-1200 Series ii Powered Subwoofer in Factory Box AS-IS

This subwoofer is in excellent cosmetic condition in the original factory packaging with manual. However, during testing we could only get garbled, distorted sound from it. It sounds like a problem with the amplifier... probably an easy fix for someone with experience with repairs. However, our repair shop could not find a schematic anywhere and refused to attempt repair. Offering AS-IS for parts / repair only. See photos for details.
