Q Acoustics Q3000WB Speaker Bracket by Q ACOUSTICS

They work and only need a few holes drilled to secure. You can tilt or rotate your speakers into whatever position you need.

These brackets were somewhat fiddly to fix to the wall, but once in place they are solid. Fitting the speakers needs some patience and requires two people. One to manoeuvre the heavyish speaker on to the bolt and one two tighten them. However, once in place the brackets are unobtrusive and the sound becomes much clearer. I used five screws in mine for a good solid fit, bearing in mind that with a slight tilt the speakers are quite heavy for a single bolt to take the weight. So well fitted tight screws are a must.
