I agree with 99.9 percent of what mojo says... 99.99 of the time... lol. My M5 on walls are laying in the garage and I'm enjoying the heck out of the M2 bookshelf's right now. So much in fact I will be ordering a set of M2 on walls when I get back to the house next week. I just have to see what MJ is talking about! Plus it actually makes sense in my audio brain that the M2 on walls would kick ass as the cabinet volume matters and I think the m2 on walls maybe hitting that sweet spot.

Lots of speakers from many
manufactures...mostly Axiom
