In london ohio, we used to have a custom square horned Federal Signal 500 AT, it was CUSTOM, but the horn broke so the horn got replaced by a round one around ~2 years after the unit was installed because the city didnt feel like making another square horn Is there any reason why they went with squ...

The ATI's are factory, not modified.

Cool. Are you planning on getting the old ones at any time?

I would, but the city would definetly not let me have those, nor would my parents and landlords.

That's unfortunate. I hope someday you'll get to acquire one.

I believe this is a Community Application Solutions RSH-462. It is a PA or paging horn but if I recall, in some places used as a voice/tone alert system.

No idea if you'll acknowledge this, but 5/13 or 5/12 port. No idea how to do 2, 3, 4. Maybe a moving stator? Curious as to how this would turn out if possible.
