And I can't perceive how ,even with Controlled Frequency Phasing, Frequency /gain /reduction in an electronic room tuning system? How it could stop rear bounce reflections produced by a Bi-Polar ESL Speaker ?..Because what ever you reduce from the back ESL radiation.?... Is also remover from the front Radiation !..So the result is ONE-POINT-SOUND-ORIGIN is shifted when a room ring is encountered. !..
But if you reduce rear reflections through physical room tuning ! One-Point-Point-Sound-Origin is retained...And then adding electronic tuning may be less severe in punching vast holes in program source...In White Room Ring literature they speak of room rings,some being as small as a 1/64 of an octave wide...It takes a very Specific Filter Set to achieve that minute of Sonic Surgery...You can kill a Rabbit with a shot gun,but how much of the Rabbit Remains Rabbit?

Phase Shifting of the rear The Diaphragm's Drive of a Double Diaphragm ESL Panel Speaker my be a better way to solve this problem,but as of yet, still ... to be invented ?

I'm sure the perceived sound is better with electronic room tuning,but at what price loss...?.
