I have the Hsu VTF-2 and it's really great. I've heard Velodyne, and a few others, and they don't come close to the Hsu for tight, quick bass. The Hsu can also rumble with the best of them for HT. The VTF-2 msrp is $499, but it's seems as though it's nearly always available for $449 on their site. If you want the same quick bass, but the ability to go ever lower, and louder, their VTF-3 does just that, and it's now available in a real rosewood veneer.
