My little girl is starting to crawl and pull up. My wife and I are worried that our speakers pose a risk to her. I have large bookshelves on 3ft. MDF stands. While they are pretty stable, an aggressive toddler could easily pull them over with a little effort. I don't want to put the speakers on the floor so i'm looking for other options. One option would be to secure the stands to the floor. Only problem is it's a concrete floor. The other option would be to secure the speakers to the stands. Not a great option because i'll have to put holes in my speakers and I don't think they would be any harder to pull over. The final option would be to buy new stands that are fillable with lead shot to make them more stable and harder to tip over. Buying new speakers (ie. towers, is out of the question according to mom.) Please help a desperate dad!
