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.

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.
