Tom, both listening distance and room size are factors, but in home situations the listening distance is far more significant. Research by Dr. Toole and others shows that in typical rooms the sound level drops off about 3dB per doubling of distance. Although the M22s are probably more similar to the AX2s in maximum output capability, the M2s with the sub handling up to 80 or 100Hz should provide you with great sound at a comfortably loud level at your 8-10' listening distance.

Despite the common use of the term, rooms aren't "filled" with sound at a uniformly high level. Your use of "near-field" indicates that you appreciate this and will be satisfied with what you actually hear where you're sitting.

Enjoy the music, not the equipment.
