Hi, B&O’s warning about fixing into studs is basically
to cover their own backs, very similar to what you will get from any
manufacturer of TV wall brackets etc. to guard against some ambitious DIY’er
trying to fix a 10Kg load into a plasterboard wall with do-it-all nylon plugs they've
found at the bottom of their toolbox.
Ideally, you do want to find a wooden stud, but it's unlikely
they will be conveniently where you need them to be. If you use the correct
fixings, then these will go anywhere on a good-condition plasterboard wall.
Something like this:

It’s worth using a fitting tool to get the best possible
grip, and DO NOT over tighten once the fitting has gripped – use a hand
screwdriver only and not a powertool, otherwise you run the risk of stripping
the threads and these are extremely difficult to remove if they go bad.
I think Rawlplug have an equivalent, but I trust Fischer
after many years of use in various similar applications. On something this close
to the wall you need to be more concerned about shearing forces than weight, there’s
also an app you can download from Fischer to calculate what you need if you are
really worried.
The fitting tool & fittings themselves are not
particularly cheap, but when you are looking to hang £1000's on the wall, it’s
not worth cutting corners.
I fitted several Beolab 3500’s, 5000’s and various plasmas
into plasterboard walls with these, not to mention heavy mirrors and cabinets, and
they’ve never moved in years. After all, they are designed to hold kitchen
cabinets up, loaded with who knows what, so a Beolab 6000 is not going to be a
problem.
Having said all that, the walls need to be in good, sound condition
and fitted correctly. Don’t blame me if it goes wrong!
Cheers,
Mike.
