What has been a favourite moment in Audio?

In the late 80s early 90s auditioning a full Cello system, I could never afford it but still in love with the cello pallete preamp. Fast forward to my financial reality 3 years ago, spent the day in LA auditioning speakers and was almost ready to give up in disappointment until I auditioned the Legacy Audio Focus XDs.  

One of my favorite moments was back in 1977 when i read about and then implemented a "Hafler Hookup" adding two small speakers in the rear--hooked up in series--to create a mock surround sound.  It was amazing with live recordings and made you feel like you were in the audience--wowed a bunch of friends until the day i was demo-ing and my buddy jacked up the volume and blew the rear speakers' tweeters...oh well, back to 2 ch...

One of our favorite reps came out to give us a spiel on some floor standing speakers. I can't remember the brand but, as he was doing his demo he cranked the volume and one of the tweeters leaped about five feet from the cabinet. He looked down at the smoking tweeter and said "let's go eat. End of demo". Everybody was on the floor rolling busting a gut. True story!

Unbelievably hilarious!  Wish I could have been there.

Now I am left to wonder how in the hell that is even possible.  Forgot to screw the tweeter in place.  Curious minds want to know!

The rep came from the Twin Cities and the store is in western South Dakota. We thought maybe the tweeter was loosened up in the drive or not tightened up at the factory. He unboxed them at our store. He would leave product at our store to demo. He came in the next morning and boxed them back up again and took them back. We would give him a hard time about it whenever he would  start a hard pitch on some "new thing" he had. He got a raft of sh*t about for years.
