Hi pkts,

The receiver/amp is likely to have a more extended frequency range but rather low output power. Check the fine print carefully, as manufacturers of mini-systems tend to play fast and loose with stating power output specs, often totaling the power output for all channels.

The smaller M2i's need more power than the M22s, but so long as you weren't planning to crank it up, replacing the existing speakers will make a huge improvement.
