Well... No. And opamp output is fully different than an opamp input. They aren't reversible.

The electronics would have to be specially designed to be a transceiver instead of just a speaker output (I mean, they definitely can do it, it just is more work and more cost)

It would be 10x cheaper just to put a microphone in it.
