Okay, new update.
I purchased the Klipsch R-10SWi, and now I'm looking to get a couple bookshelf speakers to go next to the TV. The thing is, the TV is on the mantle above the fireplace (no other option in this room) and as much as I'd like a center speaker, I don't want to try to mount it over the screen, and I don't want to lift the screen any higher up to fit it underneath. Maybe someday I'll cut a window out of the front of the mantle and mount it inside, but that's for another day...
Anyway, because I'm a sucker for the copper look, I'm looking at Klipsch cabinet speakers for left and right, and I'm noticing the much more Wife Approved walnut finish is only available in speakers rated at 75W. My receiver is rated at 50W per channel. Is that going to cause problems? Am I just going to slowly wear out my receiver cause any other issues?
