hello all,   :D

Happy New Year everyone !

Here is my new system test, I am very happy with the result, finally an OB that actually produces serious, fixed membrane system on the outside, glued.
it is a polystyrene plate 20 mm thick 1 m², the speaker acts as a piston on the center of the plate.
I replaced the spider by a more flexible and limited model Xmax to 10 mm (fs= 23 Hz), the junction between the speaker and the polystyrene plate is made with a rigid cardboard tube.
cheap system and easy to manufacture.

some images and a recorded soundtrack of the system with a pair of micro C2 Berhinger.  :D
