Revel ultima 2 salon owners biwire or not

Congratulations on the Salon 2s. I'm very happy with my pair. Unless you bi-amp, bi-wiring is a waste. Revel even says so in the owners manual. 10 gauge zip cord works great.

I agree, using banana plugs with the door closed seems impossible with these speakers. That was very annoying, because my preferred connector is a locking banana. It sounds like your problem with the upper binding posts is that you are using a thick or inflexible speaker cable. If you want the door to close and you want to biwire you must use a very flexible wire, like zipcord (which I use). If you must use a high-end speaker cable you must open/remove the door, or just use a single wire.
