I just ordered a pair of Swan 6.1BCs (thanks, Jon!). I had a question about wiring these up. It's my understanding that they can be bi-wired. Now I'm no expert on this stuff, but I think I understand the methodology of bi-wiring. My question is whether I should bother to bi-wire, or should I just use a single input. Also, will I want to use bananas or spades? Thanks in advance, and happy new year!
