Unfortunately no frequency ranges mentioned. I like the video, but otherwise:
-TC Helicon doesn't seem to have produced loudspeakers before, rather microphones and effect processors etc.
-He says a main component is from Tannoy, what happened to them? On Thomann there's nearly nothing from Tannoy, are they out of business?

BTW, isn't it generally better to have a 2-way speaker with a separate tweeter? So I would still prefer the new FBT J5A: renowned manufacturer with long tradition (even if niche supplier), detailed specifications with laboratory measurements, and my own great experiences with the Jolly 5BA. Unfortunately, the Thomann page of the former FBT Jolly 5 BA is gone since this new model is released now, so you cannot see all the 5-star reviews any more.
