One of my first “experimental expansions” happened when I saved enough to buy a Magnavox Phonograph that had two loudspeakers in the front panel.
I discovered that with wire and some external loudspeakers I could send the music from the record-player to other rooms and out into the yard. In essence I re-discovered the public address system.
At some stage in the process I decided to see what would happen if I attached a 119VAC power cord at the voice coil of a 12″ loudspeaker. Three things happened: there was a loud “POW!” noise, a wiff of smoke, and a ruptured loudspeaker.
Lesson: the power levels must be matched between amplifier and loudspeaker. A nuclear power plant is too powerful as an amplifier for a simple 3-Watt speaker.
