I'm sure someone has said this before but since it didn't dawn on me until now I figured there might be at least one other person who hasn't figured it out.
The center channel speaker in a surround sound home theater system is optimized for human voice riange. There are hundreds to choose from ranging in price from $20 to $2,000. They look incredible and come in all sizes and some are even designed to be flush mounted into the wall. The common configuration is two midrange drivers with a tweeter in the middle.
