I'm going to go demo these Polk's in the store (RTi70/CSi40) and (RTi100/CSi40), but can't with the Infinity's (IL60/IL36c). Has anyone had experience with these different sets or having any recommendations? Some info on my setup: - HK AVR520 - HK PA2000 (powering mains) - SVS 25-21CS w/ custom ports tuned down to 22hz w/ Samson S-700 - Will be used 90% for movies - Room is about 12'x24' My other thought is the IL60's and RTi100's have the powered subs. Since I'm running the SVS sub, I will probably have to set the towers as "small" since they won't be able to handle what the SVS does. So would that defeat the purpose of having the larger mains? Maybe go with something smaller like the IL30's or IL40's?
