I don't use any stands at all for my M22's. I think I am one of the very few that uses M22's for desktop computer speakers. They simply sit on my desk, about 24 inches high. For music, I am sitting right at my desk and am only about 1 foot away from the speakers, which is very nice because they seem loud to me but not to other people because I am so close to them. For music, it is best to have the tweeters ear level for best sound. However, whenever we watch movies in my dorm room, I move the left speaker on to my roomate's desk on the other wall, and my desk and his desk are about 24 inches tall, and movies sound great. You shouldn't have a problem with those stands.
Here's a picture to show you how tall everything is. The roomate's desk is over to the left of the picture, same hight as my desk.
