A few more comments. Something dumb I noticed about the Klipsch speakers is it has a keyhole mount on the back of the speaker, but it is also rear-ported. If you mounted it on the wall by its keyhole, it would completely cover up the vent! Which, of course, would badly diminish what little bass it could produce with it's tiny 4" woofer.
A couple speakers I would have like to seen included which would have been very appropriate to this round up would have been the Cambridge S30 and NHT Superzero. Also I think the Hsu and Axiom speakers don't quite belong, they are larger then the rest, that gives them an advantage in bass and dynamics. I think a 'mini-speaker' should be something like 5.5" woofers and less. 6.5" and larger should be classified as something like full size bookshelf speakers.
