You could always anchor them to the ceiling. I scared the hell out of my son when he first touched mine. He never did it again.
toddler/kid proof speaker stands
What 20-inch high speaker stands are just about topple proof ? The speaker dimensions are 24" tall x 11" wide x 9.25" deep. Speakers are wider than they are deeper. We have a toddler. Is there a way the speaker/stand can be secured so it won't topple and without screwing the stands to the speakers ? Will the regular 2-post Skylans be enough ?
