I use the QS series speakers for surrounds, and cannot praise them enough. They're terrific. If you watch a lot of movies, I think the QS speakers can't be beat for an immersing theater experience. They also do very well in DSP surround modes, as well.

However, there are those here who prefer direct radiating speakers, like the 22s, as surrounds.
