Although, it is not even really that attach the wall bracket. Much more reasonable the durchfedeln cable with a 2.5mm cross-section. This is the thin cable enclosed with the speakers not necessarily used to Harman Kardon should be able to think.
If you have successfully brought the wall mount to the wall after having somehow durchgefummelt the cable, the cable can no longer move but. There is no before and no turning back. So the cable while you are already in the holder, cut to the correct length and strip.
And if you like me has only two hands, it will be very difficult to, but then very short cables to terminals in the speakers ... All in all, not customer-friendly solution of Harman Kardon.
But since I want to evaluate primarily the sound of the speaker, not the wall bracket, it is still 4 star.
If I had to rate only the wall bracket, it would certainly -5 star.
I hope I could help :-)
