Thanks alot for all your comments . You've been a big help . Sounds like SVS is the way to go . George that PB12-Plus2 looks like a monster , 3 ports in the back to play with and 900 watts to crank up , I'd love to hear it . A little more than I wanted to spend though . I was going to buy a Velodyne DLS5000-R but I'm now considering the PB-12ISD or the PB-12ISD/2 . SO MANY DECISIONS TO MAKE !!
