From a commercial point of view in this sector I would have preferred:
1) Top flagship items maintained.
2) New flagship items announced
3) Overlap period (maybe small)
4) Old flagship items discontinued.
It seems to me that we are moving from point 1 to a point that is currently unknown.
We're not talking about consumer-facing finished products like Apple's, but about speakers that designers can invest a lot of time into developing their finished products.

At least for me, it is not a quick process to adapt to new speakers models (Simulation, 3D modeling etc) which have not yet been announced anyway.
Closed this parenthesis on the departure of MAOP 10, I would like to illustrate the personal guidelines and the temporal succession of events in the realization of my previous project which guided me in the definition of the new, egg-shaped project, which uses Markaudio 10 MAOP.
1) It all started for fun about three years ago. A friend of mine had just bought a 3D printer and I proposed to him to make an acoustic speaker instead of the usual puppets. The intention was to make a good quality pair of desktop speakers for my daughter. In other words: a pair of near field monitors for computers
2) I have been passionate about hi-fi for more than 40 years (lots of books on electronics, acoustics and almost a degree in physics and my dream has always been to create something on my own) and so I started doing simulations, cad modeling (part of my current job).
3) The finished project (surfaces connected with G2 continuity, golden ratio used in certain dimensional proportions, connections between surfaces with variable radius etc.) was printed in 3D.
4) The finished result far exceeded expectations in terms of sound quality.
5) I thought that if I freed the small Markaudio speakers from the weight of their first octave, the sound would improve a lot and so I moved on to designing the sub.
6) At first I modeled the sub using a TB W5-1138SM with a bass reflex port. However, after the first prototype, I switched to a sub with passive woofers because the reflex duct (rectangular type and made with internal panels) was too long to be determined precisely unless I did many expensive tests as well as being at the limit of a BR type agreement.
7) The new system flies and the speakers are absolutely not locatable. The dynamics, precision, spatiality and accuracy are truly incredible for such a small system and the system seems quite insensitive to the listening position.
Other considerations and construction details (I was really obsessive in the construction) can follow if you are interested.

The "egg" project".
1) Double shell enclosure (3D printed with carbon reinforced plastic) joined by internal ribs with cavities to be filled with composite in epoxy resin and fiberglass. The 3D printing possibility are truly amazing.
2) ... to be continued

Reminds me of the Apple “crystal sphere”, i am pretty sure its double shell and the space between serve a purpose. They did not have the advantage of 3D printing.
Your image is a render? How big is it?
dave
Yes, it is a shaded view of the model in the 3D modeling software I am using. I am waiting for the holidays to start the 3D printing of the enclosures. With my printer it will take about 8/9 days for the two housings. The front baffle will be made of layers of solid olive wood reinforced inside by layers of fiberglass. The dimensions are about 36x30cm for an internal volume of about 12l. The cavity will be filled with epoxy resin thickened with glass microspheres to reinforce the container as much as possible. I was not aware of the Apple project, it all started from scratch. Below I've attached a true rendering of the project, initially designed for an alpair 11MS (as depicted in the rendering) and then switched to a MAOP 10.2.

This is my previous project using the alpair 5.3 in two 3D printed satellite speakers accompanied by a passive reflex subwoofer using a TB W5-1138SW sub and it sounds incredible for its size! I have already built 3 of these and another 2 are almost ready to be assembled.
But maybe it should be dedicated to another thread.

Sorry if this has been asked/answered before, but I'm building the Classic Golden Ratio's (this planset: https://frugal-phile.com/boxlib/P10free/CGR-103-p-maop-plan-290921.pdf) and I just want to confirm whether or not the internal brace should be touching the back of the driver. It looks like it does in the plans, so if anyone had any advice for getting that fit right, that would also be appreciated. Thanks!
Yes, it should. It can be a bit tricky to get just right. Enuff so that the back of the driver is braced against the rest ofthe box but noit so much as tostress ther basket.

svwolfpack,
Another trick is to leave a small gap (~2 mm) between the brace and the driver when building, and stick a thin strip of hard foam on the brace that gets squeezed (a little) when you fix the driver on the baffle.

Thanks for the responses and the tips! I'll see how dialed in I can get it, but I was definitely toying with using a foam strip before you mentioned it, so if it turns out to be tricky i'll definitely give that a shot!
Sounds good svwolfpack, and please note that many people (including myself) have (successfully) built loudspeakers (including Planet10 Mini-Onkens) without bracing the driver magnet. It's a good practice, but not compulsory. 🙂
Have fun with your build and keep us posted on the progress. If you have questions, keep 'em coming.
