Thanks for the replies. I'll purchase smaller surrounds and put the $ towards the center. Right now I'm looking at HTD, Polk, TSC and Speakercraft (AIM 3).
I've read many suggestions that you should use the same series/brand of speaker for the LCR, as to match the tone/timbre/balance ..etc. What about the surrounds? Would it generally be OK to use some cheaper rears (HTD or monoprice) and some better fronts (Speakercraft, Energy)?
