Be aware, kids+volume+limited power=blown speakers. You can fry an Axiom too, just add to much clipped signal and you can blow just about any speaker. You might be better off with a some really cheap speakers and just plan to replace them often. Otherwise, you might have to really upgrade to get stable volume over 105dB (LOUD) (oh the good ol days of being a kid...or last week if we are just counting dbs!).
