@cleeds. Well that is interesting and it made me want to check out your system page, but :-( yet another guy who hasn’t shared. Come on dude, let’s see it and maybe I can learn something

Imagine playing a poker game with the guys; some decide to show their cards, some don’t. What’s the point ?
With that .....I’d just like to comment that if Kalali can do that with a watermelon, imagine what he can do with a sound room :^)

But has anyone ever seen instructions from a planar manufacturer advise the owner to NOT use absorption or diffusion behind their speakers?
From point number 4 in my post here.
https://forum.audiogon.com/discussions/solid-state-amps-for-quad-esl-57/post?postid=1385630#1385630
Direct from the Quad ESL owners manual.
"As a general rule radiation of sound waves from the front and rear of the speaker should be restricted as little as possible. While corners and positions closer to the wall should be avoided. A corner position is often necessary for other types of loudspeakers because it accentuates the low frequencies, but such a position for the Quad will both reduce the bass seriously and cause deterioration of middle frequencies due to standing waves."
It is my opinion
if Planar/ESL companies advertise openly to place speakers well out from the front walls, their sales would drop. So if you place them up close to the front wall you better have something dealing with the back wave. This will vary by room.
