3 articuls foam board with mtallique frame. Mtallique two grids can be disposs on the internal face of the two side panels for an acoustic scattering. The whole is mounted on a mic stand clamped on the stem of the foot. I mount on the ad hoc walk about by SM Pro Audio. In principle, it can be mounted on any foot but beware stability because it is heavy. The realization is no longer correct (made in China).

NOTICE GLOBAL

I have since yesterday. I made recordings with and without to judge the effect (see the forum). Even with cardio microphones, the effect is clear. Even with omni mics as expected.
