hello all, my question is witch center will match the best with the M3ti bookshelf speakers the room size is 14'L x 14W'x 7'H I have a built in entertainment center that does not allow tower speakers or the M22ti. I will most likely go with 4 QS4 surround speakers with a SVS PB1-ISD sub. For the receiver I will be going with ether the Denon 2803 or the HK AVR 525. thanks for the help.
