Hi,
I came across a very interesting object. I got the cheep Beosystem 4500 (BM+BC+BG CD) with a big black long steel plate. it has 6 little pins, exactly where 3 devices could be mounted.
The plate looks genuine but I never saw this bracket?! Can somebody confirm that this was an official B&O wall mounting option? I know only the "V" wall brackets, 2 per device...
