Childproofing Speakers

I have a pair of Totem Hawks and a 8 month year old daughter who is now crawling and trying to use anything she can to help learn how to stand. Unfortunately, these are not the most stable speakers they are relatively light and have only three speaker spikes in a tripod like design.
Does anyone have any experience making these speakers more stable. I have been considering outriggers from Soundocity but this would only help protect from pushing left to right and not front to back. Also, I believe, but am not sure, that I would need to drill into the speaker base to use these outriggers.

Ideas?
