Hello, there. This is my first post. I would appreciate a little advise. I have two corner klipschhorns since 1973 as the mains for a simple two speaker stereo system. Due to room size limitations these speakers must be behind me with the TV and stereo receiver in front. Now I am upgrading everything and just purchased an A/V receiver, a Yamaha htr-5590 with a 6.1 sound capability. The K-horns must remain as rear side speakers in the new setup. So it is my understanding that I will be needing two front, a central front, a central rear and a subwoofer to make things work properly for 6.1 . Could someone, or more than one, make a few suggestions as to what specific Klipsch speakers would best compliment my K-Horns for this 6.1 upgrade, and why? Details are needed here. Your comments are very much appreciated. Thanks, Jaycin
