Top .. except for one thing

I bought the wall bracket to the small boxes of devil (Concept E100) to hang on the wall.
The wall mounts were festgedübelt quickly and were stuck quite. But then when I tried to make the speakers firmly, I realized that the holes of the bracket were too small. Luckily the Platik is relatively soft and the screws could be screw hand through. Then I wanted to wire the pit and saw that the terminal was hidden. But no problem, the boxes I have tilted slightly to one side and you could be easily rewire.
