Slim wall mount for B&O Beovox Redline speakers

I made these wall mounts for my set of Beovox Redline 6000 speakers because the original from B&O were hard to find. The idea is that the inner mount if for the speaker itself, and the bigger one if to screw directly into the wall. The two mounts are assembled by bolts that screw into nuts, that are incorporated in the design. The design has a built-in cable route for speaker cables. This is a slim wall mount, that is hard to see when mounted on the wall. Works very well in my living room.
