In-wall box for MERO2 for concrete/brick wall

The WMM20 is an optional accessory for the MERO2 loudspeaker, allowing the speaker to be installed in any concrete or brick wall. The dimensions measure 96 mm x 144 mm, with a built-in depth of 83 mm. Four break-out tabs are allowing cable inlet from any direction, while the styrofoam insert keeps the inside clean and eases the plastering and finishing of the wall.
