Installation: by the turning bolt can be the speaker in cavity walls with wall thicknesses up to 30mm fast installation, same mounting technology as JBL uses. After removing the grille (carefully pry) can be the turning bolt retract clean by removing the four screws and ennehmen the LS.
Tips:
Installation in masonry:
The gaps in the plaster in the wall LS (out nibble deep 10-15cm goes without problems, have 49er brick walls built) you need for easy mounting a support for the rotary latch. Here my plasterers simply drumrum such expanded metal mesh with clean running edges with a little mortar "stuck", which were subsequently covered with plaster clean. This results in a very nice clean rectangular opening and was made Ruckzuck. So nothing breaks through the pressure of the bolt when Ankrallen out and holds bombproof. Of these component housings for plastering I do not believe. This cost (eg Canton) 60-100 euros each (!). Through my DIY version I get a much larger acoustic volume (important for clean bass), because through the hollow bricks (please inside not sealed with plaster) through the holes upward and downward a much larger volume results, as only the speakers drive bay. Modern hollow bricks mortared only except around and not flat and the cavities "thus stacked on one another.
Cable: best conduits embarrassed for subsequent conversions. For better wall sealing, avoiding vibration or acoustic shorts I glued added about 1 cm from the edge inward of each speaker from the back of the bezel around a fairly flat compriband.
