But then the surprise: the screws for the speakers are a ticking too small and keep under any circumstances!
Presumably you can the producer of the bracket for but not blame - there are probably too many different speakers. Based on the other reviews seem so most do not have the problem.
In my speakers (Devil Consono 25 Mk2) it did not fit anyway.
So run to the next construction market and slightly bigger screws for pennies concerned (M6x12 are perfect).
After that, everything went smoothly with the attachment of the brackets.
What else you should note these mounts are designed more for small speakers and should not be too much strain.
The max. permitted weight per bracket is (to instructions) 3.5 kg.
The only thing that bothers me about these mounts is the gradual locking when adjusting the tilt / rotation.
The steps are indeed divided quite fine, but bothers me anyway. Since you already can fix everything bombenfest with the upper fixing screws, I would have a continuous adjustment really liked.
Otherwise, there is not but negative that I noticed. Attached correctly keeps all bombproof on the wall and the price brackets are also absolutely fine (if one looks at what the manufacturer of the original equipment demand ...).
So all in all a buy recommendation. And think of the bolts when you have a vicious system)
