7” is the most clearance I can get between the top of the surrounds and the ceiling. Right now my MLP is 20 ft and the 100s are 14 ft apart. I can move the MLP forward to where it would be at 14 ft and the surrounds would be at 0 degree or slightly forward but again I would only have 7” from top driver to ceiling.
