I have a pair of Bose 301 Series I speakers that I like. I'd like to mount them to the wall, and looked at Bose WB-3 mounts ... which Bose expressly says are NOT compatible with 301 Series I.

Does anyone know why this is? It seems like the bracket could be screwed right onto the back. Is it because of the speaker's construction, or for sound reasons (not positioning the speaker so close to the wall). Or maybe some other reason?
