macnut5, thanks for the link to Velodyne. It seems that they are still selling subwoofers. Now, to go to their fine print: they offer just a two year warranty on their subs. Two years, and that is all. Contrast that with SVS and Axion, who both offer a full five year warranty on their subs. As on owner of a Velodyne DD12 that has had amplifier failures, I would never buy another Velodyne product.
