I was inspired by the other thread to ask this question. The only locations I have to mount the rear speakers, is behind the seating position, on the ceiling. They would like at a about the same distance as the mains, and angle down to aim at the listener. The speakers at hand are paradigm Mini-Monitors v.3 (Not exactly a small speaker for ceiling mounted rears) and I was wondering if it would be beneficial to mount them upside down, to get the tweeter somewhat closer to the ear level. Any thoughts on this?
