I'm guessing that is some kind of dam electronic siren.

It looks like some kind of speaker to me. There are numerous football stadiums and other places around here that have speakers that look identical to a T-bolt horn.

We have horns at the NY-Vermont ferry, and they have a rough-cut look of a Tbolt.

or it may be called "thundalberta"...

my favorite siren? ACA cyclone (seen and heard in person) and thunderbolt series (never seen nor heard in person)

sweet. cyclones pretty much do kick some arse.

The horn sorta looks like it is from a Thunderbolt, but the big piece behind it might suggest that the siren is a compression driver.
