Glad to see it go to a good home! I had full intentions of messing around with it, seeing what worked etc, but priorities come into play and side projects get pushed to the back burner. It's neat how the whole thing works, how the horns deflect the sound down into the tops of the pods, and that helps them resonate 360 degrees.
It's been laying up there almost 4 years now, we got it a few months after my oldest was born in November 2018. She will be 5 this year, and our youngest was born in first week of March this year.

Update.
After doing some more testing after getting the controls wired, all of the drivers died. This is very disappointing.
If you have any, and I mean ANY Federal Signal 100W drivers you would like to sell, please send me a PM!!!

Update:
Pressure washed to the point where it looks like it was never installed in Hall County, and it’s on a pole now! Still no drivers inside, but that will be taken care of eventually. The installation technically isn’t complete though as half of the top cell isn’t on there yet (having to be repaired due to a crack in the fiberglass).
Also, the siren has been converted to be a 3024 (with 5 cells in total including the dummy cell).
Here’s some photos!

Interesting how the tag was an oval since forever and will be an oval forever.

You'll spend an arm and a leg trying to populate it with Federal or Atlas drivers. I recommend picking up these from LEDequipped. They use ring terminals instead of spades, but it's only a minor thing and you can make adapters to use the Mod wire harness without cutting anything. I have their 200W drivers and they're great, so I imagine the 100W variants are just as good. If you are planning to run that unit as a 4032, you may be better off buying the 200W drivers, because that would save you some cash and simplify your setup dramatically, but if you plan to run it as a 4016, then the 100W drivers are the way to go.

That's a beautiful modulator and very good looking, kind of have a bit of dirt on the last cell on that thing. Of course what Tyler said was pretty true. But if you want to buy all 100W drivers for this thing, since I'm going to say this for you, you may have to save over a whopping 1000 dollars to buy 16 Frightener 100W speakers from them since they are 69.95 for each speaker. So what I'm saying is that you can buy those speakers what Tyler recommended for you to use for your modulator, you got to save up hella money quick.
Also one more thing, If you want to buy of a few 100W drivers you still have to spend hundreds of dollars. Not thousands.
