In my search for a 7.1 with 6 towers and a center, I've come to realize that many center speakers are more expensive than their corresponding towers/floorstanders in the same brand and line. What would be the drawbacks to using a tower speaker as a center channel speaker in a HT setup with a projection screen (mounted "sideways")? I know that center channel speakers are explicitly designed for dialogue, etc, but I'm more concerned about their application for music. My thoughts would be that dispersion might perhaps be an issue. Any other problems? Center speakers usually have a higher low-freq cutoff than the towers they are matched with, probably due to the smaller cabinet.
