One Torus in a room 16 by 22, was 11 feet wide, aspect ratio of 1.5.
1.5 compromise made for a 3 foot high, Synthesis One 12 foot wide speaker array.
The Butchered aspect ratio came compliment of Pioneer Elite which feature 1.5 ar, for many years.

11 feet wide screen shaping shell. Use round plastic extrusions (pool supply) at all points of screen contact with shell. Use putty on corners to have a sealed screen (suction).
The screen was 11 wide at the projection borders. Which was deepest point at 1 foot + 2 to 3 inches.
The center of the sucked in spinnaker was 9 inches, about 4 inches of focal depth variance. But it seems like more.
Rear projection is for a very special breed of rooms. All I want to do is to put a system that is INVISIBLE UNTIL SUMMONED.
Not for me, but for the Millions of Ultra luxurios modest sised condominiums down here, we want to preserve the OCEAN VIEW and have the big screen too.
The closest possible thing to the best optical rearscreens in front projection is a TORUS, A SIGMA RAY TRACE designed Parabola.
A TORUS FOR HOME THEATER (Single Lens) that is 100 wide 2.35 aspect ratio,
can be Injection Formed,Instead.
Empowering The HT aficionado in everyone, to install an invisible supersystem. Yes the screen would pop out of a credensa.
to enhance it with a
