So are we talking about sirens or rude posts? Someone doesn't agree with you, welcome to the internet.
The whole EOWS series was plagued from the very beginning. They were a rushed product that Federal put out to compete with Whelen in the electronic siren market. The 612, while it may look cool, is the biggest wind catcher ever. The same with the 812, 816 whatever it's called. They were discontinued around 2001-2002 due to the fact that they probably weren't selling well and were an outdated design. To give you an idea on how great the design was Highland, IL has some of the newest 612s around and one of them already has half the speaker drivers busted.
