HI can anyone give any advice on how these mount to the wall, is there a special bracket? Have just bought a second hand pair but think they are incomplete. Thanks,

... you'll need special brackets - the original ones have been discontinued years ago -
but fortunately STB-Brackets are producing replacement brackets ...

Or make them yourself. It's not so hard to do. Just a piece of metal with 4 holes!

Cheers for the responses does anyone have a decent photo of what they should look like the on the website is not that clear. The speakers seem to have a plate in each corner with a spigot at 90 degrees to the panel with a hole in it should it attach on all four corners? Thanks

Are the set screws what goes through the holes in the brackets on the back of the speaker itself?

Mounting is easy - install the STB-WB level to the wall - and put the panel speakers up

The Beovox panel speakers CAN be mounted to wall by just having two long screws with big head on the wall (ie. leaving them about 2-3cm from the wall). My BV3000s have been on wall like this for about a year now without any problems. A wall bracket would, of course, be the best option, especially for the heavier Beolab models.
