While I don't have the exact set-up, I do have the M22s running with an LFM-2 (VP150 center and QS4s for surround) and a Yamaha HTR-5960 receiver. The space is small -- 12'x13'x8'. While I have only had the system for about a week now, so far the LFM-2 does a very good job of blending in with the M22s. I went with the LFM-2 because I thought the cost/performance ratio was much better than with one of the Axiom subs.
