Can just a speaker in intercom panel be replaced?

[ahlondon]

Outdoor doorbell-intercom unit lets the residents hear outside from their handset in the flat, but the visitor cannot hear any of them. Handset issues have been ruled out. The speaker was making a loud cracking sound prior to failing which I read is a sign of a speaker that's about to die.

Can I swap it to a similar sized speaker? I can perhaps get it out of an old radio or desktop speaker and solder it?

Yes but it will need to be the same size / ohms / and power rating …also not be a paper cone speaker as they don’t stand up to the weather
