I'm after small bipole/dipole speakers for the rear 4 channels of a 7.1 set up. My last ones (Monitor Audio silver fx) were pretty large. I like the look of the Monitor Audio in ceiling ones ... could they be mounted in custom pods on wall for instance? The Monitor Audio sound frame look good, but don't have a dipole/bipole version. Any other brands? My front speakers are very niche hifi brand, so I have no intention to match the brand/sound of the rears to them.
