Have you ever thought about putting 4.5's all the way around, my buddy just did 6.1 with 5.5's all the way around (center channel is also a 5.5) and it is amazing! Sounds incredible and he did it all for a song compared to buying new speakers. You'd only have to buy 4 more speakers to do 6.1, assuming you have room or a need to do something like that. Matching speakers rock for home theater, actually if you could hear towers all the way around you might wonder why anyone would want to use anything else other than for asthetic reasons. Crossing them over at 80hz is fine, the towers still sound better than a surround type speaker IMO.
