Pearl Acoustic Sibelius

As in a folded ML-Voigt for it? Sure. I haven't done any myself deliberately to avoid any potential for treading on Harley's toes, and also because in many cases, I can't see the point of the configuration since an MLTL does the same job in a simpler enclosure and there is no visible difference.
I can to an extent vouch for that. One of Scotts design for the MAOP 11 is going wonderfully LOW as well as maintaining the silken HIGHS so signature of the MAOP group, all in an MLTL enclosure....
 
Not at all & very much appreciated. I can confirm Eastern Bay Sound is absolutely legitimate though, with to date all the acoustic design work done by me...😉

Well, I'm not so sure about you, me old mucker, but you don't catch me compl... :rofl:

Depends what you mean by 'offensive', but presumably 'different strokes for different folks'. More prosaically, it's more a question of the power response than the direct and the MS units with their negative camber cones are slightly peculair old Hectors in that sense as things even out quite significantly in-room, which wouldn't be the case if you didn't have that axial amplitude kick; one of the characteristics of the negative camber is that direct-bonded cap has some blanking relative to the conventional shallow-profile designs, and the main cone itself is still producing a reasonable amount of higher frequencies -by intent it doesn't shrink in effective emitting area as much as some of the others. Negative camber aside, you sometimes see similar things with whizzer-cone units.
 
For those seeking to do an homage to Harley's loudspeaker, this interview might provide some useful info.


In other news, resident luminaries Scott and Dave got a shout out (aka design credit) from a new company producing a MarkAudio-based work of art, the Eastern Bay Sound's Southwind.

Great stuff.
I was a little amused by how Harley compared a tiny mic for the entire full range performance to large speakers that have like 3-way to achieve something similar… made me wonder about our on ears/mouth design 😳
