Best stands so baby doesn't knock speaker over

Dtx, simple. You get high strength scotch double sided mounting tape, the red stuff. you run three long strips on the bottom of the speaker and three on the bottom of the stand. If you have a carpeted floor run four 3 inch self tapping wood screws into the floor. Drill pilot holes in the base of the stands and run the screws through the carpet into the subflooring. Trust me on this. You will have a very hard time separating the speaker from the stand. A child will never do it. Removing the screws is far easier. You will not leave a visible mark in the carpet. 

My favorite story is my pal that had a nice stereo and a small child. The child pushed open the CD player, put a big handful of oatmeal on the tray, then pushed the close button. That was funnier than watching tweeter domes get pushed in.

Good luck drilling into pile without running it.

My bedroom speaker set is wall mounted on extended brackets.

MC I belief the word you looking for is belt, however it is not the child fault that he have speaker in the bedplace. My suggest is to cut hole in carpet and have tour wife sow it back right around base of stand. All done.

@tubebuffer haha I agree!  My daughter is actually excellent with my speakers.. Never touched them because I instilled in her that these are "no no's" from day 1.  But yes a belt would work too.  I would just prefer to have sturdy stands.

Surely there are stands with super sturdy bases.
