This is an interesting installation; the owner had a very limited and difficult space to work with, but needed a solution that would improve his sound. Notice the Velodyne subwoofer right next to the CWD equipment stand! This was an extreme test, both from a standpoint of compatibility and pure torture from nearby low frequency vibration- and it worked brilliantly, not just in improving the sound quality from his entire system, but also in reducing or eliminating feedback and skipping problems the subwoofer's proximity had previously caused with his CD changer. "You have made me a believer" wrote the supplier of this picture. Thanks, Verne!
