Rti a5 mains csi a6 center and fxi a6 surround
P363 mains ps351 center and 163 surround
The Infinity line would save me around $350. Using the same dual psw505 subs with either setup.
Well I actually already have all the polks and now I just ordered the Infinity 363s as they were 107 a piece shipped but deciding which ones I should use as the main system in my living room. I am thinking of using the Polks as my main system surround sound and using the 363s as a 2.0 system in my bedroom.
