Hey guys, I'm just starting to piece together my home theater system. Current Setup: Sony 60" SXRD Yami RX-V2400 Receiver KLH Floor speakers with 15" subs/4" mid etc..(old as dirt) Polk 5.1 surround sound (RM500 or something like that) HT PC PS2 Prog. Scan DVD/Tape combo etc.. I'd like to update my speakers, particularly the old ass KLH's and was looking for a nice pair of floor speakers. Figure about $1500 for a pair...maybe more if the difference is significant. I was readking about the Polk RTi12's and they seem really nice. I'm happy with my polk setup right now for what they cost. And will I need a seperate amp for these speakers? I believe the receiver is 120x7 or thereabouts... Thanks!
