Speaker - terminal connected to the AC line?
William R. Walsh Inscribed thus:
Hi!
That gives me an idea for testing subwoofers ...
Connect each speaker terminal to the active and neutral of a
mains supply.
Now come on, haven't you watched enough Youtube to know what happens
when you do that? ;-)
Interestingly, the very idea of connecting a speaker to the AC line is
mentioned early on in my copy of the ARRL's "Now You're Talking" book.
They tell you not to do so, and I suppose that there are some people
out there who need to be told that...more so because they'd hurt or
kill themselves in the process.

Many years ago I used a 6.3v heater transformer and a loudspeaker as a
door opening alarm. 50Hz certainly got your attention...
