Greets!

No, not per se since the written portion just gives an example, not a 'carved in stone' design like some folks have interpreted it, with the drawings indicating the various concepts not covered in the various Bell Labs/W.E. patents.

>The terminalogy used today fits neither the physics or the history of pipe design. I guess this is my main point. Voigt pipes, MLTL's, TL's, TQWT's, back horn, corner horn, you get the picture.

Well, the physics hasn't changed, not sure what you mean WRT history, and for sure the nomenclature has changed over time. ML-TLs, multiple resonant cavity (BP) designs were lumped in with 'reflex', Voigt pipes/any flavor of TL were lumped together as 'Acoustic Labryrinths', and anything that had a positive expansion was a horn regardless of whether it had a reduced exit (vent) or not.

>I agree with you (agreeing with me?) that the B-is-B is a corner loaded back horn. As such it works completely different from the LCN TQWT. So, I can't consider them the same or correlaries of each other.

Anyway, keep me straight!

Right, though located as shown in his write-up it's just a folded BLH since it's too far from the corners/ceiling for proper loading, though my SWAG is they're close enough for some down around Fc.
