Help with blown tweeters/power issue

All,

Last night I was happily listening to my new speakers - the largest audio purchase I have or ever will make - when my amplifier’s display  blinked on and off, AirPlay cut in and out, and then wham - the volume jumped up to max with no input from me.  
I immediately shut off the amp, but I fear the damage is done.  The speakers and amp still make sound, but all I hear from the tweeters is a soft, high-pitched hiss. I assume they are blown, and I have no idea what else could be wrong inside the cabinets. 
I have no idea what happened.  My only thought is that the dryer was on nearby and could have caused some sort of voltage spike to the amp.  When I turn on a nearby dehumidifier the lights dim momentarily, which makes me suspicious there is some power issue at play.
I have two questions:

1. What do I need to do to assess the full extent of damage to the speakers?  There are no dealers nearby. 2.  How can I prevent this from happening again?

Thanks for any help.  This has been an awful experience.

No idea if your speakers or amp are blown.  I'd get a cheap pair of speakers and try them.

I suspect it's either your amp OR your amp and your speakers.

It's also difficult to tell if you have merely surges or surges and sags. You may be one of the few people who actually needs voltage regulation.  Get an inexpensive voltage meter to see how low your V gets.

I strongly recommend ZeroSurge, or Furman power protection. 

Best,
