Synergy, what do you think of the HSU sub? I came across his subs while looking for one for my Home Theater system. He gets UNBELIEVEABLE raves about his subs. His high end one can be had for like $1000, and supposedly sounds as good or better than $3000 subs. He also has a boxed sub that is only like $350, and supposedly sounds as good as $1000 subs. The old model had a couple of complaints, but I hear the new model is even better.
