Its partial filled cavity, 50mm insulation boards.
Thats exactly what i don't want, block falling into cavity!!!!! :cry:
Has anyone installed any multiroom systems,good recommended ones??
What i meant was internal wall is 100mm concrete block, then 80mm cavity to 100mm external wall.
System planning on installing is Russound CA4.4iL.
This site is great, best response ever!!!!!
Installing multiroom audio into new build.
System requires US back boxes for keypads. Size: 56mm x 98mm x 78mm (w x h x d)
The problem i have is the depth of them. My walls are only 100mm deep.
Has anyone come across this problem?????? :( [/img]
