Velodyne DD-15+, a proven winner. If you are looking for a home theater subwoofer they might be worth a look. But for critical listening of music I'd pass.

Vandersteen, NHT, and Rythmic all make outstanding subwoofers. Why would these be any better?

has anybody else heard of high velocity subwoofers? if you're not familiar with them you can go to www.sourcespeaker.com and check them out. my dealer said they make the concrete floor shake. they have 8, 10 ,and 12 inch driver models. let me know what you think of them.
