Depends on how the speakers were supposed to be wired on the second radio. The speakers aren't really interchangeable unless designed to work the same.

If you hooked your suspect speaker up to a radio that uses a different kind of speaker and got silence, it doesn't necessarily prove anything.

If you test step-by-step to find out whether the field and voice coils are good, then we have a starting point to troubleshoot your radio. It isn't that hard. As I said above, it shouldn't take more than 10 minutes with your ohm-meter. It's a max of 3 simple steps to find and test the field coil and one more to test the voice coil. If either the field coil or the voice coil is open or compromised then we know the speaker is bad.

The only other way to check the speaker is to put it into another radio that you know is working that also uses a 1700 ohm field coil (or close to it) and a voice coil that returns to ground through the speaker frame.

Swapping out speakers willy-nilly is a waste of time and could easily damage something. You can swap out the speaker with other radios, but you have to know what you're doing and work carefully. Testing the speaker properly is easier and takes less time.
