I am building a new ht system to be installed next week. Its for a 13'x14' 12' ceiling. I have a Onkyo 702,a Pioneer PDP-5060HD plasma and just bought some Polk Rti6, Csi5, Fxi5 and a SVS PB10-ISD sub. I was wondering if should use Rti8 instead of the Rti6. Bookshef + stands is almost the price of the Rti8s. I could easily exchange them.
Does the change will make a big difference?
