I just received two 6T6 towers, and I've got a 6T6 MTM single back ordered until May. The towers are being driven by my new Onkyo SR705, and they make my heart sing.
That said, I've got a question about where I'm going to have to put my MTM when it shows up. Because of the layout of my apt, and the fact that I'm using a projector setup, the center is going to have to be mounted off of the ceiling just above my screen. With a good downward angle, is that sort of placement going to noticeably degrade the quality/purpose of a center channel?
