Sits firmly and delivers what they promise.

They were looking for speaker wall mounts for boxes of Sony SBT300WB - compact system. The holder should be adjustable swiveling and inclination, because the boxes were not placed at the same height.
The mounts fit exactly into the scheme. The attachment of the holder is simple as adjusting the angle. It should be noted that the angle plates have space on the back wall of the box times 145 mm sufficiently to speakers with approximately 65 mm. In my boxes to be mounted, for example, was the bass reflex port in the center of the attachment site. Nevertheless, I have the disk mounted respectively so displaced sideways that only a part of the opening was obscured. Sonically I hear no difference. ;-). The hooked plates are secured with small Allen screws. Prima thing, but somewhat tricky, especially if the boxes are mounted close to the wall corners. I came here on the one side of the box is no longer on it, but a screw is also sufficient per box. Prima thing and my daughter is also satisfied.
