A Redone Version of my Whelen WS/WPS 3000 Siren. I think that the throats are one big piece not forged into the side of a wedge like shape but are instead like a 4004 but with the throat moved to the side and molded shut on the other side (You'll see on the model what i'm taking about). This version also doesn't have speaker drivers but I did make a Whelen ESC-864 and some new whelen siren setups like a older and newer 3000 and a whelen 4004 with a modern all steel pole. WHY ARE THE 4000(x) & Vortex R(x) MODELS LARGER THAN THE WS 3000!!!!!!
