You need your center to match your mains. This would be a major mistake if it didn't. Matching the sourounds is even better but now as important.
center channel speakers --- low height
I am installing a home theater and I have a size constraint for the center channel speaker. It has to be no higher than approximately 6 inches. The Revels and the Sonus Faber won't work and I didn't particularly like the sound of the B&Ws that would fit for this application. Any recommendations?
