I have (accidentally) used a 60 Hz 120 volt sine wave (probably more square than sine, the amp was clipped and limited) for distortion tests with a four ohm B&C18SW115-4 speaker with no "explosions".

A much lower level than that did cause a pair of AR voice coils to continue travel in to the magnet structure after separating from the cone when the spider bottomed against the frame, made surprisingly little noise.

Peavey used to do the "plug it into the wall" demos with one of their speakers. Of course its impedance peak was right at 60Hz. Still, an impressive trick.

Not 800 (or 1800) watts because of the impedance spike at 60Hz. It might have been 140 watts. The demo wasn't long, cause it was LOUD. A good trick.

At such voltages, wouldn't you need insulated binding posts? None of that fancy gold plated stuff here

Yes you do. There are some standards about that, tho I don't know what they are. Using Speakon connectors insulates you from that problem.

Default Peavy gets it right

I used to blame Peavy for driving me away from live shows. Chances are the entire audio chain was harsh in the 80's.

Default Peavey

I thought so. Thanks for the spell check. BachmanTurnerOverdrive came to town and I loved their "blue collar" song so I bought a ticket and went to the show and lasted maybe 10 minutes.
It's good to know that pro sound and hi fi are no longer enemies
