I'm using Infinity IL40's and the 36c as my fronts and IL10's as surrounds currently. But I'm going 7.1 and wanted to figure out the best way to do this. Normally, I'd just get another pair of 10's, but Circuit City is selling the 10's at $200 each and the IL30's at $225 each. Would the extra $50 per pair be worth it? So which senario would be best? A: Both: IL10's B: Both: IL30's C: Surrounds: IL30's Rears: IL10's D: Surrounds: IL10's Rears: IL30's Thanks!!
