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.

Sounds like you have it sussed out- the tweeter is blown and the crossover is good.

The tweeter blew because the amplifier used to drive the speaker was clipping (same as in your son's speakers). If you don't plan to go to a more powerful amp, install a fuse in series with the tweeter so that it blows instead of the tweeter. Fuses are a lot less expensive! I'd put the fuse holder right by the tweeter.

Regarding the amplifier clipping, I really don't think that was the cause.  I have an old Llano 200watt (400 into 4) amplifier driving the speakers only down to 80hz where the subs take over.  It's a pretty solid amp and I don't really listen that loudly .... lot of jazz.
Guess I didn't mention (and you had no way of knowing) that I have a Bel Canto PrePro everything is hooked thru and something just happened to it.  It literally went dead ... no sound from any source or any of the 5 channels.  Although I didn't hear anything, and the other speaker is fine, I'm thinking this did it.  Happened pretty much at same time as tweeter.  I'm trying to contact Bel Canto, but having a hard time getting a response.

Sucks!!!  Blown tweeter and PrePro.....  no listening for awhile!

The tweeter is dead! Years ago I paid $150 for a M20 tweeter.

I called and they said these are $128.70 each.  I'll probably buy a couple of them.  Not sure why cheaper?
Thanks again everyone for the help.
