What became of the guy making OB speakers about 2 years ago?

Yep, Linkwitz is the first one I recall, a real og. Unfortunately he passed away a few years ago. Also Emerald Physics was the big thing for a hot minute some years ago (well before the Shaw Caladans). Still a number of those floating around. Not sure about its company status, but should be an easy search. 

I'll admit openly to being baffled as to who the OP is referring to.

“OB’s seemed to be produced and endorsed by real eccentrics ;-) “

All you have to do is listen to them.  I own Cornwalls, Heresys and KEF LS50 Metas as well as Caintuck audio open baffles with Lii Song Fast 8’s.  The sound is incredible for Jazz and Vocals - otherworldly actually.  I guess that makes me eccentric.

IIRC correctly Spatial Audio (Claytons former company) evolved from Emerald Physics.

Suspect you were thinking of Clayton Shaw as noted above.

In the words of our most eloquent President, Mr. Shaw is best described as

"a very very bad man."   You really do not want to send a penny to this individual.
