jackme,
I think you misunderstood what i was getting at.
If you buy M22s for your fronts, i was assuming you were going to put the second pair of M3s in the rear as surround speakers.
Hence my post to the comparison of direct speakers as surrounds in the back vs. the QSx series.
If you like the sound of the M3s, then buy the QSx surrounds.
If you are a looking for a slightly more detailed sound up front then changing the M3s for M22s should be your preference.
