Hope to get some advice. I have an Onkyo 605 a/v receiver. My front speakers are Klipsch B-3's, the center is Klipsch C-1. The side surrounds and back surround (1), are Bose 201's. I am so impressed with the Klipsch speakers, I want to change the surrounds to Klipsch B-2's. My question is, can I use use one of the B-2's as a center speaker. I can still return the C-1. Since the C-1, and B-2 pair, are about the same price, I would only have to buy an additional pair. Also, can the B-2 be laid on its side or does it have stay upright. Thanks for any help!
