I think you'll benefit from a subwoofer as well. Try looking into a used pair of NHT SuperZeros or SuperOnes and a used NHT SubOne, or consider a pair of PSB Alpha AVs and a matching PSB sub. Once you're done I think you'll be pretty surpirsed how good your 2-channel movie system sounds without spending the big bucks for a multichannel setup. Good luck and have fun.
Two channel home theater set up
I am thinking of setting up a two channel home theater in my family room. I have an 80 wpc kenwood receiver but need advice with the DVD player and speakers. I am looking for some two way monitors ($400 max) and a DVD player with virtual or tru-surround capability ($300 max). The monitors should have >90 db sensitivity since my receiver is current limited and they should reach as low a frequency (45 hz preferably) possible since I am not planning on installing a subwoofer. Feel free to comment and suggest any speakers.
