I think they had some drawings on their former (Italian) homepage. As far as I can remember, the magnets sits behind the teak decor. There have been a few reviews of them, very much praising the sound quality. Price is ridiculous…

I had a problem with there depth of 57mm i believe that include the teak strip and the magnets. Then they say 20mm excursion... either there magnets are super thin. Witch could be, or 20mm is xmax total swing so actually 10mm . I think the last but 20 sounds better of course. Why use the typical one way travel when stating xmax .....hehe

Anyhow love to have a peak inside to confirm what i believe push pull ribbed planar magnetic just like apogee.

The Alsyvox must mean +/- 10 mm, which is a lot for a planar woofer. Maybe it is something like the Apogee woofers? The Apogees are are bit more long-stroke than Magnepan. Magnepan can do +/- 2 mm in the center of the diaphragm, nothing along the edges. Maybe +/- 1 mm average for the whole driver. A Magneplanar-style driver need to be large. Analysis Audio is also a bit different. The woofer has a surround of an elastic material that allows for more excursion.

I believe the general arrangement is as you suspect. The patent application by the designer appears to mainly deal with details of construction, in particular stability of diaphragm tension while using thinner metal frame. But, I am basing that on the provided online English translation which may not be exact. Both attached...

FWIW, I heard them at RMAF last year and they were one of the few rooms I went back to multiple times to hear different types of music. Mids and highs were lovely with surprising amount of heft and definition in the bass range.

Well, my experiments show that its almost impossible to make the stroke shorter, if using neodymium magnets! The force required to overcome the repelling effect is quite overwhelming in the case of a woofer with 300 magnets...

bolserst, Thanks for the pdf of the patent. The FIG 6 is missing. To me, there is nothing that indicates the possibliity of a +/- 10 mm stroke. The plastic film cannot stretch that much, it seems to be fixed aorund the edges.

The stroke is one thing, the distance between magnets is another. I have made a double sided version of my woofer planar, and the stroke is never over +- 5mm using a 100watt amp. Also, there's very little difference in SPL, around +2 dB using front and back magnets.

Working on a new singelsided version now with two turns of 12uM Alu-strips as conductors, 6 mm wide and a total of 4 Ohms.
