But... how the heck did you get the M80 upside down above the TV?
Simple answer…no W.A.F.
More precisely, my apartment lease doesn’t allow anything nailed to the walls so when I made my theater I built a frame to hang curtains from around the inside of the entire room including a façade even with the front of the TV. Part of that façade includes a shelf originally for my VP150. Not only did I overbuild it a little bit as luck would have it there is just enough room for a M80 to sit vertically on the shelf above the TV. Also didn’t hurt that I spent 10 years seriously into power lifting before I got back into running recently.
The vertical separation between the tweeters on the L/R main M80s and the center M80 is just over one and a half feet, almost the same as it was for the VP150.
