I've actually once thought of an LRAD serving as a 'siren'.
Just one question; can it run with something like a legit electronic siren controller (e.g UltraVoice) without a tone generator (Or did the UV has a tone generator built in?)?
I'm pretty sure they can run on a siren controller. You'd have to be careful of the tone the controller produces and the wattage the amps drive the head at to keep the heat down. The XL driver in the 360X series is rated at 320 watts, and that's what LRAD's amps push it towards. They are also built a little differently than an ordinary compression driver, so they might not be able to take a lot of heat and stress.
As far as their controller goes it's basically an MP3 player from what I can tell. They can load tone files into the memory that can be played back through the speakers. As long as the tone is clean it will work just fine. If I'm not mistaken the only difference between this and most other siren controllers is that the tones have to be manually generated vs something like an UltraVoice which generates it's own tone files on the spot and plays it back through the amps. The system of ATI's at Ft. Rucker do this, albeit with tones straight from Whelen's tone library, and they work fine. At one point LRAD listed a "360XS" siren series on their site that from what I can tell basically implemented this design. They removed the series, probably because it was redundant.
