A couple years ago I got curious to just how the Q’s would sound as stereo speakers (in a R/L configuration). I reconfigured my receiver so that the surround back channels would be a second zone and played some music through that zone. They sounded pretty good, much better than I thought they would, but it just didn’t sound right. As others have mentioned, the sound coming from them was omni-directional, sorta.

If you wanted to use the Q’s as area speakers, like for instance a really big room where you might want speakers off the floor and on the wall instead, and were just looking for general background music, I think the Q’s would do very well. But I don’t think they would do very well in a surround set up as the mains or the center. You want precise imaging for these channels so sound follows the image in front of you, and the Q’s don’t do that.
