Yes, I do. I have two, and they were taught from about the same age as this kid right from wrong, to respect other people's things, etc.
An old drinking buddy of mine and I both had our first kids around the same time, and quickly followed with our second. we also both had the large, floor standing speakers for our stereos.
His wife was the type that didn't believe in "restricting" the kids as far as what they could and couldn't do, touch, play with, etc. around the house. As a result, by the time his kids were five, he had replaced the speaker grilles twice each, as well as both bass drivers, before finally giving up and getting rid of them and buying smaller bookshelf speakers.
I, on the other hand, made it known that the speakers, as well as my turntable (a very expensive high-end model) were "Not a toy. These are daddys. You don't touch." Once, and ONLY once, (at about the age of 3 or 4) did one of my kids push on the speaker grille. He got his hand slapped. Lighly, but enough to enforce the rule. End of story.
I still have the speakers, and turntable, BTW. In perfect working condition.
