Can speaker be heard underwater?

With the speaker at full volume, can it be hear with the control unit underwater and user not underwater? I'm talking about a calm fresh water lake, not the ocean. If so, how deep underwater before no sound is heard? Don't have one to test. That's why I'm asking.
 
I am guessing that after it floods it will make no sound just like the CTX. Hopefully I am wrong.
 
It depends on the design of the speaker, but most likely it will not make any sound. Sound is caused by vibration and the density of water would require a far more powerful speaker driver than it probably contains. If it has a sealed member that leaves an air pocket around the speaker cone, it could transfer sound from the speaker through the water, but it probably doesn't have that either.
 
Yes. Witness the AT series from Garrett. Now Minelab put a speaker cutoff on the CTX, so in that case no. My *guess* would be they did the same on the EQ. They gotta sell some overpriced accessories somehow! Lol..
