Most replies here are saying that it's OK to use this fixing or that
fixing, but I've a feeling they're missing the (major) point in that
they are fixing to a plasterboard stud wall, and yours are not stud
walls.

Your walls are built with two sheets of PB stood upright with
basically a giant eggbox keeping them apart, and no timber or metal
struts are used for rigidity.

That's exactly what we had in our previous house, Paramount partition
board. The speakers must have been there for about 20 years with no
problems.


Your speakers were 8kg? - his telly is 12kg and will probably get handled a
lot more than hi-fi speakers, cleaning, adjustments etc.

A stud wall has (usually timber, but more recently, box aluminium)
struts running up and down and also across - this gives the wall
much more strength, and using PB fixings here is usually OK because
each fixing will generally be no more than 6 inches away from one or
more of these

... with a studs only 12 inches apart ?

No, the studs are usually 16 inch centres, meaning that unless you fix
directly in the centre of studding, which is highly unlikely and you would
be seven inches away,(the studs are normally 2 inches) anywhere else at all
and you would be six inches or less from a studding.
