Phantom mode is the way to go if you don't have to make it sound right over a wide area. If it's for just 1 or 2 people the phantom mode will frequently sound better than using a center channel.
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?
