TD, you appear to have misinterpreted the info on the Monitor Audio surrounds, since as Ken points out it has nothing to do with what you're trying to suggest. Those surrounds are an example of designs which have a switch to either have the tweeters playing in phase with each other(bipole)or in opposite polarity(dipole)which results in differences in the dispersion characteristics. The Axiom QS drivers all operate in phase.

Any surrounds can be used in 5.1 setups if you have two or 7.1 if you have four.
