The Velodyne CHT series is far better than any other subs I heard while shopping at the local audio stores. I own the CHT 12 and CHT 8 and like them both very much - for what I bought them for (home theater and music for CHT 12, secondary stereo with M22s for CHT 8). However, I have never heard the HSU or SVS subs and the folks here seem to be pretty reliable so if they say they are better than Velodyne they probably are. But if for budgetary reasons you end up with a Velodyne, rest assured you will be pleased. I had a "find the best subwoofer for under $200" mentality and also ended up getting the CHT 8 from JandR.
