Summary: The frequency response for these speakers is amazing. very crisp, yet full bodied low end. I use them for the front and side channels of a 7.1 system. The rear's are the ceiling version of this same speaker (it is round, but uses essentially the same components) Even with subwoofer off, they sound very rich. I have gotten many comments from house guests on how amazing they sound. very well built. can't beat the quality and price.
