i would think you would definitely lose some sound quality by placing the speakers so close to the floor.. it would help if you could angle them up toward the listening position, but this will still only help a little.
the M22's should most definitely be placed on a stand, or a shelf with breathing room. if the 'look' of the stand is a concern, i think the M40's or M50's would probably be your next option.
i think by putting the speakers so close to the ground, you would be defeating the purpose of getting good quality speakers in the first place?
