I’m starting to upgrade my home theater system and I need some help. I was given a NIB Klipsch Icon KC-25 center so I figured that I would build my home theater around it. I have a Yamaha RX-V671 with an old set of htib speakers that I am replacing. From what I’ve read I need to match the center with the front L & R … something about timbre matching? Can someone please tell me which bookshelf style speakers match the KC-25?
