Very eye catching. Any chance you can upload an audition on YouTube?
I’ll chime in with Dave, an audition would scratch my itch as to how the 1.5×7’s perform.
I’d given one of the PE folks a mild *tsk* for not having one to display @ the ’23 speaker competition.
They look like an item for a line array that could make ‘a minimalist speaker design’ look overweight…*L*
….but just jesting.
