If it makes one loud pop, you *had* a speaker. :^)

Also, if you have a VOM (most voltmeters are VOMs), you can check
the wires leading to the speaker for resistance.  If it's a
speaker or a combination of speakers it will usually show between
4 and 16 Ohms. Reverse polarity of the leads and you'll get the
same thing.

If it's a siren, you'll usually get a low resistance in one
direction and what looks like an open circuit or a very high
resistance when you reverse the poles.

Yep, or the wire is broken.
