Fred, thanks. I do have an AV reciever it is a Marantz SR-19. I currently use the 2 of the pre-out's (L & R main) to divert the signal to my HSU-Research sub amp crosserover at 43hrtz, then it send the signal back to to the Marantz amp to the front mains. My amp also has a multi room connection which will divert the input source to an alternative amp. I may have to play with this set-up but I think I have something to work with here. I'm also think of selling my Marantz and purchasing an HT pre-amp like Parasound ) Geroge, I did not recieve the private email, I recently moved to another state, I will check and modify my profile, please resend tomorrow morning as I'm on-line at work (not allowed, little time). Jim
