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. William Many years ago I used a 6.3v heater transformer and a loudspeaker as a door opening alarm. 50Hz certainly got your attention... -- Best Regards: Baron. |
