I was in the process of building stands for my M80s, but due to time constraints, I had to abandon the project for a while. In the mean time, I confiscated two of my wife's end tables (~21" high) and have the M80s sitting on those. Luckily, I remembered to take the spikes off first before placing them on the tables. Now the tweeters on the M80s are roughly the same height as my center channel and to be honest, I can't tell a difference between them sitting on the floor vs. on the tables.
