I bought two of these TV brackets - and am really happy with this choice. Because ...
1) ... keep these things deliver what they promise. The boxes do not move a millimeter longer, the construction is top!
2) ... the suspensions are highly adjustable. the boxes can be hereby positioned at various places (I've got it as a side speaker for my 7.1 surround system in use) - as desired. In addition, the inclination angle, which can be set relatively large. According to the brochure's are 20 degrees, but I did not remeasured. For me it fits. Other products provide us with specific only 15 or even 10 degrees.
3) ... these constructions are considerably cheaper than original suspensions for speaker boxes.
Unrestricted buy recommendation!
