Is this approach inherently small and quiet? I've been searching for an approach for omnidirectional speaker cabinets for live performance... The bass of course is omnidirectional already, the question is how to get the high mids and highs distributed omnidirectionally too... Fascinating stuff to me, despite my ignorance.

Poor choice of words. "Quiet" would mean low noise background. What I meant was low decibel output.

I spent some time on some other omni threads here and am fascinated by the reflector for the speaker that points straight up. I tried doing something like that for a guitar speaker and gave up on it in favor of an animated approach... I may have to take that tack up again and see what the right shape really ought to be.

This is so funny , i can always recognise ur ribbon speakers by the corrugation

Also funny is that i kind of made the same thing with an esl. but damping the inside was kind of hard. higher frequency worked caus it would not exit the other side, the lower you go the more difficult it gets.

thank you for replies and kind words.As i have listened more to my speaker system I have discovered its not as linear as expected.I have to EQ -5 db at 9000hz And it acts a bit like a linesource .I am buying messure tool for a REW calibration.I am crossing at 1200hz.

I think that much better omni ribbon tweeter is like o.e. Elac ELAC – Klang lebt – FS 609 CE:. I dont know how they solved that ribbon to not touch near parts like magnets in order to avoid rough distortions, but I think it is soldable. But, only I can not see what is purpose of such omni tweeter like your also, if have radiation of sound backward. There will be just reflection from walls, so these can not be real HI-FI speakers in regard that high frequencies should be sourced from one point.
