I've noticed that both Pierce Sales and Bob Shultz Sales have a different microphone replacement than the previous Speco SPC-6 white speaker. Are these new units just black colored Speco SPC-6's or are they different?

I believe you need to install the correct resistor so the mics are calibrated to the control box.

Bottom line is I think there is more than just buying the mics you saw in a cataloge for 10 bucks.

I looked into it as well and that is what I found.

If not, let me know.
