Hi
I would like to thank everyone that visited us at the recent Munich HES show, and for the overwhelming positive comments.
Even though the Pallas was not the only new design to debut (we launched a series of electronic designs using our prop NOIES technology) , plus some tricky digital things

, the Pallas certainly stole the attention from it's accompanying electronics .
Some more information regarding the design
It is a four way, semi active horn speaker.
Construction wise, it's bass wings are 20mm thick solid alumium and woofers are cross braced (for force cancelling) using stainless rods.
It's front horn sections are stacked plywood construction, solid ply sheets glued, and milled.
The finish is called Liquid Peal and is 4-5mm thick proprietery finish which gives the certain textured look.
The bass section is comprised of a folded open baffle , with 16 12'' woofers in total. Each woofer can handle 500W and is driven by 500W amp each, so total 16 x 500W for the bass. The woofers are custom AE units with low fs but with accordion suspension and are very light and fast.
The filters are analog with multiple adjustments.
Midbass section consists of a 110Hz modified tractrix midbass horn (stacked ply) loaded with a 8'' field coil. The FC works as compression driver as we designed special front/back chamber and a special phase plug (aluminium 3d printed PG). Midbass covers 115-350Hz
Midrange section uses again a modified tractrix horn with full rollback to minimize diffraction.It uses the 667 driver (modern version of the 555 driver) custom made in DE.
HF section is a true foil ribbon driver loading our new tweeter horn. You can say the whole project begun with the development of this new HF horn last summer. The modified tractrix horn is 3.5 times deeper than our previous HF horn and is a very different design than our previous designs.It allowed us some very different voicing strategies for the speaker.The foil is dipole and it's firing to the 240mm tractrix to the front, and an inverted horn to the back (to absorb the back wave).
The heart of the speaker is of course the (external) crossover which hosts the passive (constant GD filters) for the three horns, the analog filters for the bass and the Bluetooth module. As well as conditioning filters for the field coils.
The Bluetooth module is a version of the same tech found in Contendo and Aurora that allows significant level of adjustment to the speaker.
Each channel/speaker comes with two four-channel amps for the bass which sit on the plinth of the speaker.
Cheers
S
