I just replaced my Axiom AX-1 Center channel with a single M2i. The results: a little more accuracy, a good deal more clarity, and much better dispersion of sound than can be had from typical w-t-w center channel speakers.

The M2i does improve upon its predecessor. Treble is a little smoother than the M2ti, and the 1" tweeter and voice coil makes the speaker look nicer. This is quite a versatile speaker. Works very well as a small center channel. Have mine on top of the t.v, upside-down, tweeter nearest the screen. Clean, neutral, good focus, and oh yeah, baby, DISPERSION!
