Can a laser pointer burn out a square dance speaker?

No way! No matter what kind of laser pointer you have, the power will be less than 3.5w, and anything past that is a false alarm.

But it is estimated that after a few years, diamond laser pointer can be sold, the power can be as high as 360w, small size. Totally capable of burning out stereos.

Now, it is estimated that you can only buy c o2 laser tube (industrial grade), which is estimated to be able to burn out the stereo (power can be up to a few hundred watts). But it's big and complicated to operate, so you shouldn't count on it.

Nowadays, square dancing is a very common thing, you can give the person who jumped to discuss, if you can't, I guess you can only hand over to the city management to deal with.
