Thanks for the suggestion of flipping the speaker upside down. Unfortunately dual CCs in your configuration won't fit in my basement. In the area where the duct is running I have 78 inches from floor to ceiling. The Center is 7.5 inches tall. The screen height for a 100 inch screen is 55 inches (with border) meaning that I'd be cutting it close with a 16 inch stand. I guess I could go for a smaller screen but I'd rather shoot for the 100 inch mark since it jives well with my seating placement plans.
