Has anyone tried putting a tower speaker on it's side as a center speaker? I am running Klipsch RF-3's and am about to upgrade to the RC-3 center, but was wondering if another RF-3 would work better? I have heard before that ideally you would want the same speaker all the way around. I saw a picture of one that the guy had cut a new face for it and built a center out of a tower, with the two woofers flanking the tweeter, and that wouldn't be hard to do, but I would think that the woofers would have to be the right distance apart and away from the tweeter to get the best results. Any comments, ideas or suggestions?
