Just stumbled over this:
ARMONIA Loudspeakers
..... that is a new way to do AMT. Pro is it will allow for a much deeper pleating, and therefore larger surface area for the width size ... also nice touch with a special section for tweeter ....
Good inspiration 🙂

Thanks. Very interesting!
This design as it hung in the air from the outset. After the appearance of narrow and strong neodymium magnets was made.
Now can take a step further. Make low-frequency transducer with deep pockets.

This design demonstrates that there is no free lunch to be had by manipulating the elements of the motor. In this case the magnetic flux direction has been turned through 90 degrees compared to a normal AMT. This allows greater pleat depth; but that is about all. To achieve this we have an even longer gap; necessitating the magnet structure be segmented along the pleat height dimension.
They seem to allude to dipole radiation but do not show it in the animation? Efficiency must be rather low otherwise we would not need something one metre long. The TICCS is a line array with an SPL that falls at 3dB per doubling of distance whereas the woofer(s) are a point source falling away at 6 dB. I have heard speakers of this nature and didn't much care for the effect.
Even though they have been in the market place since 2008 they don't seem to have attracted much comment, favourable or otherwise.

Why so negative?
Take it as good inspiration ... maybe to rethink the design again ....
... and there can be many reasons for it not having success ... sound could be one, but marketing (or the lack of) could be another ..... or something else .....
