I like omnis. Having heard the original Ohm's decades ago, I was enthralled by what I heard. Never could afford a pair, never had the space to live with them either.
However...the current Ohm's are not a true Walsh radiator. They are a pleasant experience and a good affordable line of speakers.
Google Walsh speakers. Look at the 'images of..' page. You will see amidst the pics the original Ohms, with their conical elements. You will also see the current Ohms as well. If one keeps looking, you might notice a pic of what's UNDER the cylindrical mesh under the grille.
It's an inverted speaker; likely carefully chosen or design, but fairly typical.
But it's NOT a truncated cone as in the originals.
There is a big difference in that. The Walsh patent goes into why and how.
I've been engaged in DIY'ing Walsh radiators for my own bemusement for awhile now, 'spoofing' a slightly larger version of the DDD driver used in the German Physiks units. They're not 'perfect'....yet. But, having heard the 'new' Ohms as well as the 'old' Ohms, I'm pleased with what I've been able to accomplish so far. Not 'audiophile' quality....yet. But I spend more of my time of late listening to my 'steampunk speakers' (a friend's observation, which actually tickles me) than my 'regular' speakers, 'warts' and all.
The new Ohms are nice speakers. I will not speak negatively of them, as they fill a niche. HHR offers an updated version of the original design, and I believe they appear at some shows. HHR is a true Walsh unit. Both concerns are 'web-only' companies.
And then there's MBL. Omnis about as far as current tech allows. They're supposed to be fantastic. And at their price, they'd better be.
I'll carry on with what I'm doing. *S*
