Testing former alarm system sirens with stereo
Testing speakers from a 1980s alarm system with a stereo. Was successful and showed that they worked at most sound frequencies. The radio speaker unfortunately went kaput as I was hooking it up to the stereo- should've known- came from a 1950s-60s radio.
