I've had my ML Aerius' for 6+ years with two sons - now 4 and 8 - and had no problems. They are very kid-proof in my opinion. The speakers are in my basement family room where the boys spend a lot of time. Of course, we're not playing with liquids around them, either. That said, I recently picked up a pair of Silverline SR12's for under $500 that I'm using in place of the ML's for now, and I'm enjoying them just as much.
