Protecting Equipment from Children

Be firm, like this guy,

All the best,

Put a high voltage fence around your stereo.

Speaker grill, hide remote..teach them to stay away and tell them why. When you explain to them reasons they might appreciate that more. Let them know the materials are delicate and made of slik and are very easily destroyed. Tell them it has to be thin and light to work and do it's design.

Also giving them a $20 bill to stay away will work best

Little ones, like puppies, need constant surveillance. It’s just the way it is. Then this cool little two letter word, universally known, works wonders. It’s NO. Firm but not harsh said with authority that conveys the seriousness of the moment. Boundaries seem to have been forgotten in todays world. Works with my grandkids, 2-6-8. Never an issue.

What everyone said above. Also push the speakers back
close to the wall and put a sheet or blanket over
everything else.
