Hi All,
I'm trying to fit speaker brackets to a room. I've hidden the wires and tried the following fixtures for each speaker:
I filled the void with expanding foam during installation, hoping that it would relieve some of the strain on the plaster by spreading the load. I also cut a small frame of hardboard to put the fixings onto, again to spread the load and make it easier for them to expand. This worked very well on one, but after a weight test, the other failed, damaging the plaster. I've removed it, and having a filling-job ahead :-(
There doesn't actually seem to be a void at this one, the plaster seems to go back to the brick. This is visible now that half the wall is apart! Is this normal? There is definitely a void at the bottom of the wall.
Can anyone suggest any options? Having routed the wires, I don't want to give up. My thoughts are:
-speaker/picture frames, like these
-buy a stud detector to find a more solid part of the wall to attach onto
-mount on the adjacent wall (it's a corner). Could have the same problems. This wall also has a similar void mentioned above at the bottom (where I worked on another backbox), but the void may not exist at the top, like the one I'm working with.
-somehow mount directly into the brick (possible?), with some sort of stage to bring it out to flush with the wall. I now have a hole in the wall that would facilitate this already, as a result of the first attempt!
-give up, assuming plaster just can't take the weight
Can anyone help? Googling seems to get me nowhere useful...
I've had the same speakers up on the wall in another home successfully, which was more modern and had prefab plasterboard, so it shouldn't be beyond the realms of impossibility!
