I've been considering an M22 for center channel. The idea of three M22's is very appealing, actually. I can get all three for less than the price of a pair of M60s, and would have matching fronts for my home theater (which is the best way to go). I didn't realize these were magnetically shielded until today, which makes this a reasonable scenario for my setup (though the center channel may look funny sitting on top of my TV until the video side of my theater gets replaced).
As a question (don't want to open a separate thread just for this), is there any reason why I shouldn't get M22's across the front instead of M60s/150? I have a good subwoofer, and the speakers are going to be crossed over at 80Hz anyway. I have no plans on bypassing the sub for music, thus have no real concern for low bass reproduction from my mains. About the only thing I can think of is that the M60s would likely be better for larger rooms, and would have more output. They would also gives me the benefit of listening to music in "pass through" mode (no processing, thus no sub... a feature in the pre-amp I'm looking at). Of course, I didn't buy the sub so I could bypass it is, so this scenario is not likely to happen often - if ever.
It seems my budget for audio is shrinking lately. I go from Thiels to Axiom M60s to M22's. It may have something to do with house-hunting (and preping existing house to seel it), as well as the new family addition that will be arriving shortly. I doubt playing "loud" is going to be an option for me for a while, anyway.
From all the reviews, the M22's/sub seem to be a good way to go. But again, I have no experience with any of these speakers, so I could be dead wrong. The M60's may be head and shoulders above the M22's, in which case, I can hold off a bit longer in order to get the better speaker.
