[Jukebox-list] Extention speaker

[Ron Rich]

I am not sure that that model had "70 volt" taps (Rockola Charlie ??). Look at the amp and see what the markings are--that should tell you what type of speaker(s) you can use--Ron Rich

Most jukebox extension speakers are of the 70 volt variety.
The impedance is irrelevant because the internal transformer
is designed to properly drive the speaker coil, and the
wattage is set by a switch or jumpers on the transformer.

70 volt speakers are a big advantage in these types of
installations because they allow setting the relative
volume of each speaker independently, and the higher
transmission voltage provides much less line loss than
low-voltage "home audio" type speakers.
