I too bought those stands as they were recommended for the M22's but once home, found that they were indeed too low.
You want to have the tweeters on the M22's at the same height as your ears are when you are seated. Measure that, and then buy some stands that will best fit.
You know that the M22's tweeter is 17"-18" from the floor when the speaker is placed on the floor, so measure from the floor to your ears when seated and subtract. That's how tall you want your stands for the M22's.
Of course you also want the tweeters on your mains and center to be as close as possible too. You'll have to find a balance inbetween. My VP150 is a bit higher than my M22's (even on the larger stands) so I've tilted the VP150 down a bit to aim more directly to the seating area.
