Speaker destroying audio streams.

Firstly, it's great to see a forum that makes sense to have.

And now to the problem...
At AV con earlier this year there was an incident where a few videos had audio that came out quite awful (loud, distorted, scratchy). On my PC when I was testing them, everything was fine. At the convention out of the amp and into the speakers we had set up, it kinda destroyed the speakers, blew out the cones (I think that's what they're called).
Any ideas on how to prevent this from happening again?

Get better tech guys.

AWA had a minor problem with it this year (that they fixed before I even knew about it) when exporting from PC as the audio was being amplified by both PC and main amplifier causing issues.

You just need to do tests. PC audio has a limit on it's amplitude designated by the nature of the format, so it's just a question of making sure your amplifiers (pc and external) are configured to cope with the gain and make sure the amplifiers dont double each other up.

Do you know twhat the decible capabilities of the Amps were? cuase that makes a huge difference. One guy I knew made speakers taht couldplay at 900 deciples (enough to stop a human heart). I still don't know why he did that.

Unfortunately everything's been packed up for about 4 months. So I'm not sure on any numbers, I can't really remember any.
Better Tech guys. Yeah, I've got a few electronic engineering grads (I think that was the name of their course) organised, hopefully they can handle it.
Test the equipment. Probably the one thing that wasn't done. (I can still see the Hard Disk not detected error messages)

Also would it be an idea to lower/increase the volume of the audio in the videos, so they all play at the same volume?

You shouldn't need to. Your videos will be compressed in some way anyway so reducing the volume will just make them sound worse in the long run.

Just make sure you get people who can set things up properly. If you are getting grads then see if you can get someone who has got experience in sound technician work for student theatre or something like that

The audio still sounded extremly muffled/distorted throughout the convention; very bassy. Whenever anyone spoke into a microphone, I struggled to pick out what they were saying. Do you think this was due to the acoustics of the room, or some conflict with what you were talking about?
