Just saw the April issue of DVD Etc magazine with it's review of 18 subwoofers. It rates the DefTech supercube 1 as a 97, same as the Velodyne HGS-18. Only the infinity sub is rated higher at 98. These three subs get the highest rating. Wow! Good to see such a comprehensive comparison. Those looking to get a sub, check the reviews out. As a supercube 1 owner I can vouch for the fact that the supercube rocks! Jester.
