What aspects of a speaker determine it's max volume?

Two things can go wrong with a speaker.

The coil can push the cone too hard and it rips. This happens a lot with older paper speakers.

You can put too much electricity through the coil (a little transformer) and burn it out.

The volume produced is (sort of) the diameter of the cone times the travel in and out. That tells how much air it will move.

Also, some speakers are more efficient than others. If you use a lighter weight Mylar cone, it takes less electrical power to move the cone than a heavy paper one, and you can move more air.
