thanks cthomp for your info. So your saying its imperative to run a crossover? The reason I didnt want to use speakers that need a crossover is b/c i dont really know too much about the whole crossoverthing as far as instalation, setup, fine tuning, etc.

How do the speakers you mentioned compare to the speakers that are being sold at BestBuy/Circuit City? Any speakers there of very good quality and are what Im looking for?

Still not to sure about what to do with size combination for front and back and if that nessesary. Also is it better to get a speaker that is a 2-way or 3-way (what are 2-ways and 3-ways?) v.s a speaker that is not?
