Luke, I'd agree with Peter; don't bother. There are relatively few W series owners, but there haven't been any reports of problems with structural vibrations. The main energy of the speaker, by far, is projected outward similar to the result from a free-standing speaker placed near the wall. Axiom prizes its neutral sound character highly and it seems probable that testing in a typical room didn't adversely affect that character.

Enjoy the music, not the equipment.
