Thanks for the input. I currently use a pair of Barbetta Sona SE41C's connected directly to my 9000Pro. The sound is very good! Since I play a lot of organ I was wondering what the improvement would be with a quality subwoofer. As I was looking at the various subwoofers I noticed a new model from Behringer. It is the model B2092A. It has some interesting characteristics for the price ($200) but I normally would expect to lay out $500 and up. At that price I would almost be tempted. If it didn't meet my expectations I would not be out much. Comments...
