Hello Phil,
I don't know if the impedance would be correct, or if the sound
quality would be adequate, but one source of unusual speakers
is to pull them off old modems. I've collected a few over the course
of time.
Best Regards

Mine used a 1" diameter circular speaker
with a transparent Mylar (?) cone.
$DEITY knows what its impedance was, the wires going to the cone snapped off
while I was desoldering it... My schematic lists the speaker as a 220-ohm
speaker. Obviously I've read the label off the wrong part...
Does anyone know where I could get a 220-ohm speaker? Grant Searle
(http://www.home-micros.freeserve.co.uk/JupiterAce/JupiterAce.html) says he
got his from an old ZX Spectrum...
If it would help, I could put the speaker on my PC's scanner and upload a
100-or-so DPI picture of it to my website...
Thanks.
