Right now I have 4 Paradigm Atom bookeshelfs for the front and rear surround, and a Paradigm CC-170 for the center speaker. This is in a 5.1 surround system. I just purchased a Yamaha 5760, and now I would like to move the front Atoms to the rear center to make a 7.1 system. What I am looking for is suggestions for the front surrounds. I would like a pair of tower speakers that would match, soundwise, with the existing speakers. What do I need to look for, to make it sound right? I can't just go buy any speaker, right? I want it to sounds right. I don't want to spend a lot of money, is under $300 possible, but I will save up for whatever is worthwile. Can anyone suggest some good speakers? Thanks The receiver is Yamaha 5760. Just some more info to add that might help. The room is 20ft wide by 30 ft deep. But the system is setup is a corner of the room that is 16ft deep and 13ft wide. So I have about 7 extra feet to the right, and about 14ft behind. The main reason I added that info, I want a bigger sub also, what do I really need in a room this size? I only have a Paradigm PDR-10 right now.
