Ça a l'air pas mal du tout...
Mais pour avoir survolé les 2 notices pdf du 1er post, je me pose une question tout de même : comment fait-on avec une config 2x12 ou 4x12.
je suis allé faire un tour sur leur site, et dans la FAQ, on a un début de réponse :

3. Is the Deeflexx suited for 4 X 12“ cabinets?
(1) No – the beam of the higher loudspeaker continues unchanged. The Deeflexx has been developed for loudspeakers close to the floor, with the loudspeaker height maximally 50 cm – see the operating instructions.
(2) Yes – with reservation: In close-up range (up to approx. 2 m angled cabinet, up to approx. 4 m straight cabinet) the sound is brightened up (no beam audible), only at a specific distance away does the beam of the higher up loudspeaker become audible. The audibility increases impressively within the close-up range in smaller rehearsal rooms and on smaller stages, the beam only has an audible effect when further away.
(3) Yes – with reservation: Two Deeflexx units are positioned in front of the bottom loudspeaker, the sound is dispersed as with a 2 X 12“ cabinet. The higher loudspeaker is switched off or is disconnected, so that it functions as a passive membrane as with a bass reflex system opening, the deep frequencies of the active cabinets are enhanced. The sound behind the cabinet is not as transparent, while the reflected sound of the higher cabinets are screened off. (Example)
(The impedance of the loudspeakers change when one disconnects them, first consult an expert!)
