I know this is a little off-topic, but I had a spare Beolab 6000 lying around, so I've fitted it with a Beolab 3500 wall bracket, relocated the wiring to the centre of the column and added an extra end cap (where the base used to be). This now sits happily up on our playroom wall (out of the reach of tiny fingers) and runs directly from a Beosystem 3500 in the next room via Powerlink.
It looks just like a Beolab 3500 but without the display - I'll try to post some pictures if anyone is interested?
Basically, where I'm coming from is that there can be all sorts of options with Beolab speakers, especially if you're willing to make a few minor alterations..... ❓
Cheers, Steve.
