From what I can make out, it is something like a mass loaded transmission line but more horn shaped. They're using a less than ideal shaped transmission line for the low end, and they've added a bass reflex pipe to it as a bandpass to filter out all of the unwanted rumble. What are your thoughts on this one?
Or maybe like this edited picture ( wall removed ) (?) Try measuring the depth to the wall inside the enclosure through the reflexport with a ruler.
Something simular:
Remember the Atelier First Horn with a big opening in the rear (?) ...which rear mouth later was fixed/repaired with a plate ( also with a relexport ).

Here is a blow up picture of his last design. Still same design as the atlier first horn.

Exactly and Vivace is done the same way. No new wine in these canadian bottles. Still i don't understand the several name shift, first Atelier then Gemme Audio and now Arteluthe.
I did some repair work on a set Gemme's a while back. I forget the model (Tanto?) but they used a beryllium tweeter and a carbon Morel midbass. The cabinet was interesting, from the inside it seemed like something of a transmission line / back loaded horn variant. The fellow who owned the speakers seemed to know a lot about the designer/company and their history. I believe he said Gemme was sold off to a larger company and the designer parted ways and started a new company. Hence, the name changes.
Wow. I had no idea this company went out of business? Speakers looked cool but, never got to hear them? Jm
I had a pair of the ateliers first horn, I made my bass plates with instruction from the designer. It worked, it did extend the bass low, it sounded good. I could hear a dips in the mid bass tho. I wish I still had them, I wanted to experiment them with different drivers.
Its been a while since I've heard them but I remember enjoying them. The fellow bought them as Gemme was closing down and they were put together rather questionably. We had to rebuild the driver cutout outs as half the screws missed, rewire the tweeter on one as it was out of phase, the crossovers were simple and definitely not the ones that should have been in there.
Once they were fixed up, they made some good sound. Bass output was impressive for a 6" driver. They had a very nice set of electronics feeding them which only helped.
In short, I wouldn't be upset if they were my main speakers. Wouldn't be my first choice though (nothing against them, just preference).
Interestingly a pair of Alpair 10.3 metals, 7.3 metals and chr70s gen 3 held their own at moderate volumes. The person actually said he wouldn't be upset in the least if the Alpair 10.3s replaced the Gemmes.
I still can't understand this drawing/plan. Is it sealed all the way down to the hairpin turn or are there leaks along the way from the driver chamber? Is there a better plan somewhere - I would like to model this.
An externally hosted image should be here but it was not working when we last tested it.
Sealed behind the driver, and along the line. Takes a hairpin turn at the bottom. There is a verticle holy brace in the rear section.
Imagine the red marking is the perforated plate ( or what Robertburchell calls "verticle holy brace" ). It's mounted there for avoiding unwanted resonanses/vibrations. Hope it makes sense !
Just for illustration purpose, i've edited the atelier horn.

So the triangle driver chamber is isosceles triangle with 10in sides ? What is internal width and what is output vent csa ?
I don't know the dimensions for Arteluthe Satie only what is shown on the drawing for the Atelier Audio First Horn = 36" x 7.5" x 15" (H x W x D) cabinet construction is all 11-ply Baltic birch.

X- I think the annotated photo and exploded sketch might be for two different designs? - so you could be modeling a chimera - but then, hey, who knows, it could accidentally be something wonderful
stranger stuff has happened
OK, so KrammeAcoustics beat me to that point

I don't have high hopes for the model to pan out a revolutionary speaker. Looks a lot like constricted bass output so SPL will not be high in bass area. I have yet to see anything that provides as nice of an overall bass gain and big sound like a Karlaonator. I should build a full size one for a 12in one day. Would probably blow my socks off.
Could be an illusion ...good point chrisb. 😉
I promise you, if i ever win in the lottery, i will buy all their loudspeakers and saw them into pieces and show all how they are made.
Anyway, i think the concept was born by a coincidence, when they tried to close the First Horn with a plate, for fixing unwanted behavior. 😀
And just some final thoughts on this - while scrolling through the original 6Moons review of the Vivace, (November 2007) I was again amused at the "defying the very laws of physics" , etc -
Heard these a few years back, and the FE108Sigma is a delicious performer in the midrange band, but no effin way you'll get usable 20Hz from them in an enclosure that size - or possibly any, including a Kleinhorn. An Alpair10.3 in a simple MLTL would eat these for breakfast.
Pretty cabinetry though
note also that when the response to a web search is "inquire about this domain", that's not usually a good sign.

Vivace is in my opinion a cat who believes it's a lion.
Yep "defying the very laws of physics" was the words ..hmmm 🙄
20 hz must have been near field measurements ( very near ). 😀
The cabinets are outstanding and has a very nice finish.
"inquire about this domain" ? link ?

Some similarities: BLH with hairpin turn and constricted terminus and a acoustic obstruction like perforated plate or K aperture. Karlsonator combines back wave with front wave and sends it out the front.
