Guy, when M22s are paired with a good SVS sub handling the low bass, it's questionable if switching to a tower speaker such as the M60 can be realistically termed an "upgrade". Keep in mind that your M22s use two 5 1/4" drivers, while the M60 uses one. If anything, the M22 therefore has greater dynamic capabilities(can play louder with low distortion)in the important mid-range than does the M60. The larger enclosure brings no benefits above the bass, and your sub handles the most difficult part of that.
