I'm interested in buying a decent 5.1 set up for my den over the next couple weeks, nothing crazy just somthing better than my ancient sony HTiB. It's primary use would be for watching Blu-ray movies(PS3), followed by gaming (xbox360) and lastly music & hd cable. The part of the room dedicated to the surround system would be about 15x12. Starting out my budget is about $650 I want to use that to get the L,R,C and a receiver. After that in the next week or two I'll buy the SL,SR, and a Sub for around $300-$350. I would like tower speakers for the L&R if possible, alot of people of the forum say that Polk Audio is good, I was looking at the moniter 50's and 60's would these suit my needs? If so what Center should i get along with what Receiver to power them(and eventually what surrounds and sub)? I'm new to this so all suggestions are appreciated. With my budget and needs what system could I build to give me the best bang for my buck? Thanks alot!
