A new horn is brewing in the cauldron?

I was looking at classifieds and ran into a tekton model.

But, my curiosity has risen more about the speaker in the background instead, which doesn’t seem to be listed on their website.

It looks kinda like a B&C horn paired w/dual 15s maybe... seems smaller than the Jubilee, maybe the size of a Klipschorn...

Any Tektonians from constellation Tekton have a clue on what model this is?
