Hello tshepherd,
You may hang or bracket-mount a QS8 to a column, but you cannot mount it inside a column. The QS8 uses dual top- and bottom-firing woofers on its upper and lower surfaces, and angled tweeters on the front baffle, so enclosing the QS8 in any fashion would defeat the speaker's multi-directional "quadpolar" characteristics. It's the latter that makes them so effective as ambient/surround speakers.
The Axiom Full Metal Bracket is compatible with an inset mounting bolt on the QS8s rear baffle, which gives it considerable placement versatility.
Regards,
