I don't know what dipole means. the bose cube speakers are double speakers. One cube on top of the other so that you can cahange the directions to "fill the romm"
Dipole speakers in essence have two drivers, one 'in phase' and one 'out of phase'. This is supposed to give a more diffuse sound to the rears. However, they dont tend to work well, if at all, with automated setup systems, and will pretty much always report as 'out of phase', as well half of the speaker is out of phase!
I have Mission dipole surrounds and they always come up like that on my Denon auto-setup.
I don't know about the cube speakers, but if they have two drivers I suppose its possible they are dipole?
