Cavity insulation

Our invisible loudspeakers are already equipped with acoustic foam on the back.
In order to guarantee perfect sound reproduction, however, the use of stone wool in the wall or ceiling cavity is indispensable.
It must be ensured that there is enough space for the loudspeaker so that the insulation does not squeeze against the loudspeaker. We recommend to remove approx. 5 cm / 2 inch from the stone wool behind the loudspeaker*.
