Are these Rumbler siren speakers?

Found on the front of a Dallas Fire-Rescue ambulance, currently not assigned. I was wondering, are these the "Rumbler" speakers? Can't think of what else they may be...

Yes. It looks a little different than the federal version or maybe thats a cover. But those look like the rumbler cones.

Somebody finally figured out how to install missle launchers on an ambulance.

Looks like they are "Rumbler" speaker covers. I would love to see how it feels to be laying on a backboard or stretcher when these are "rumbling" away. Might feel like a nice in bus massage.

Seth, I believe that is the Whelen's version of Federal signal's Rumbler. It is called the Whelen Howler. Both are low freq sirens.

Great way to clear traffic.

From inside the vehicle they don't sound like much (akin to a vacuum). But when you get in the path of the sound waves - yahoo.
