I also bought a pair of the 150's, a CSi30, and a pair of FXi30's on clearance. A friend has a pair of RTA11's he is willing to part with for a good price. Anyone have a recommendation on the better speaker 150's or RTA11's. Oh yeah, I haven't purchased a receiver yet. Any recommendations, reasonably priced. I'm still on a budget. I have read the 150's require alot of power and I know the RTA11's are more efficient and are 6 ohm rated.
