I have a PW2200 and recently bought a second one.
They are quite decent, mostly because of the larger amplifier in them. I've heard a few subs in their price range that do perform slightly better though, but my own experience with subs has been pretty much that you get what you pay for.
I spent about 7 weeks sampling subwoofer after subwoofer and other than the benefits associated with increased power for bass frequencies, I couldn't really find a brand that seemed to clearly win over any others. There were a few obviously over priced ones, but nothing that really stood out in each price range. I really liked Velodyne because I had always heard they were the best...in the end I got a better deal on the Paradigm and went with that. I've been satisfied, but I've always wondered what is the best way to demo a sub-woofer?
Any comments?
