Tweeter Blown OR Crossover? How to check?

I have a pair of Revel M22 monitors that I suspect one has a blown tweeter (no sound at all).  Am planning to purchase a pair of new tweeters, but dawned on me that I should check "output" at the speaker wires where the tweeter is .... maybe not tweeter and crossover instead?

How can I check that?  Can I clip leads onto those wires and hook into a small bookshelf speaker to check?  Or is that a no-no?

Nothing labeled on the tweeter to say positive or negative .... just one white wire (with blue stripe) and one black wire.  Guessing the white is positive and black is negative?

If it is the speaker, I'd guess I would install the new tweeter same way and hook up wires according to which way they are now (same) since there aren't any indicators on the speaker itself....

Please forgive my terminology if incorrect.

Contact a 1.5V battery across the tweeter terminals, you should hear some popping noise if the tweeter still good.

Did you test yet?

Since the connections are all soldered, I haven't undone the connections yet.  I did pull a tweeter out of an old, small Polk bookshelf speaker and ran leads from the Revel connectors on it's tweeter (but they're still connected  /soldered to wires going to it's crossover) to the Polk tweeter itself.
Turned on a source to test and No sound from the Polk speaker.....  Is that a "true" test without unsoldering connections yet?  I would have expected the tweeter to make sound.  Since it didn't I'm not sure it's the tweeter?
I have done a tiny bit of soldering (and unsoldering) before, but since I'm not great at it, I wanted to try to test somehow without unsoldering the nicely done solders from the factory.

Thoughts?

I think I have a meter around, certainly not an expert at using it.  Sounds like I need to unsolder one of the wires and test.

Boy do I feel stupid .... the tweeter I tried from the Polk doesn't work even in it's own enclosure.  They are a set my son used and I didn't test them before I used them for testing.  He must have blown them or something.
Regardless, I pulled the 5.25 inch driver out of the Polk (that is working!) and ran leads to the Revel tweeter connectors and YES, there was sound coming from the 5.25 inch speaker ..... so there is "sound" coming from the tweeter wires of the Revel .... so I would think that tells me the crossover is working?
