This is what I have & not sure if appropriate to set up this way: Carver Amp TFM-35, VTL preamp, Denon AVR2500 receiver, Polk Audio all around. RTi12 (2 front)running from Carver amp because it only have 2 channel. The Denon receiver have 5 channel which I plan to use as follows: The 2 front speaker channel from receiver will put in the rear, 2 FXi3 in the middle & of course center go to center. I'm thinking this way I will have total of 4 speakers for front which I'm able to hear it from front & back as well. How should these speakers arrange to the correct way for best sound quality? I'm just a rookie and needed all the help. Thank you & always appreciate your input. Also not sure if the receiver have the output for my Polk sub. Not familiar of how to use the receiver yet!
