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....As in a folded ML-Voigt for it? Sure.

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...😉

If you really want to get the most out of the Alpair 11MS, you need to redesign the pipe length, taper and volume. The 11MS requires a slightly larger, slower breathing enclosure.Excuse me, but is it possible to make a "Sibelius" speaker with the Alpair 11MS?
Just curious.
Well, I'm not so sure about you, me old mucker, but you don't catch me compl... 
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.

Some are sensitive, some not. A11ms has some ringing thatannoys me, a couple coats thinned gloss sorted it enuff so i no loger noticed.

I still think an Enabled cone on the Southwind would.be in keeping with the baroque character of the woodwork and would help in the performance too.
Maybe the dashes could have serifs or something with more flair too.

creative translation! sounds yummy hahaSlower breathing?![]()
It's about time that claims are backed up with measurements….Well, that's because it is -as I've said before, it's based on the 10.2 and 10.3 with modifications to the motor design. No secret about that.
did you ever come across the paper template for the A10.3? could you share please?
Yes. It, a bunch of otners, and the callipers in a Fostex driver box.It was on mutable … looks like it has migrated somewhere.

I didn't realise it was 'a claim'It's about time that claims are backed up with measurements….

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 😳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.
