Would have been perfect

to really have mounted without the unit to the wall and thus tested, the holder makes a high impression and would determine its function excellently fulfilled. The Winkelverstellmöglichkeit is easy but stable.

Unfortunately I have to return the parts I had ordered at the same time parallel to the maintenance heir the speaker system. From me was not taken into account that the mounting plate does not fit.
Although my boxes are not exactly small (about 25cm high and 18cm wide) is the backplane largely occupied by the cable box and a bass reflex port. Space for mounting the bracket is therefore not available as they can be mounted only vertically.
