Im a begineer. I have two 8ohm 0.25 speakers. I want to use one as a mic and other as a speaker. I have a transformer which can supply AC voltage of 4, 8 or

12 volts from room powersupply.

Hi DirectXXX,

It is OK to use a speaker as a mic.
You will need an amplifier.

Connect one of your speakers to the amplifier's
input, and the other to the amplifier's output.

Amplifiers run on DC.
