I’m sure I’ve been at a show where there were some but I can’t recall hearing them. For a while Yamamura was in cahoots with some minor nobility (member of the Churchill family) and was trading out of Wardour Castle in Wiltshire and I think they were making & selling a version of these speakers from there.
I was contacted by someone 3 or 4 years ago who was trying to write a biography of Yamamura & seek out some of his more ‘out there’ creations. I was also sent pictures by Peter from Deco of some bits that a Be customer was chopping into the shop. A mad looking unipivot arm with ceramic tube, a Melco a-like heavyweight turntable he’d made and some fairly extreme speaker components. I may still have the pics somewhere. I’ll have a look. Yamamura turned up at Munich in 2016 if memory serves with some very large horns on static display using the larger Ale compression drivers.
