I've been looking around for the 7200s, but not having too much luck. On ebay, there are many of the 5530s and was wondering if they are similar, besides the size. I know that I like the sound of the 7200 and the 5530 looks like the driver out of an rt25i that i used to have. Will it be weird to have 2 7200s and a tweeter for center channel and 2 pairs of 5530s with a tweeter for my left and right? The rears will be some in ceiling speakers and the subs will be 2 polk dx10s (car audio subs) downfiring on a bash300 amp.The receiver is a denon avr3802.
