Well, I looked up Whelen Vortex R3, and it still has 4 throats. Is one of the throats empty without a driver?
I think either that or the drivers in the throats are of less wattage.
Whelen only uses 400 watt drivers supplied by Community Loudspeaker. R3 has one throat empty.

Basically what Eows said. As far as I'm aware Vortexes only had the finback option too, though I'd need someone else with extensive knowledge on Whelens to verify that.
Does anyone know the purpose of the fins on the older models? Was it just for looks or was it useful in some way? Sorry if this is common knowledge.

I think it was to better distribute the weight.

I think it had something to do with Wind.

Why would they drop the fins on the newer models (if they actually did) then?

Very honestly I have no clue. My answer was just speculation.

My understanding is the first gen Vortex rotators are belt driven as opposed to later gear driven models (it’s obvious from looking at the boxes the first gen Vortex uses a very different type of rotator). The fins better handled the wind load so as to reduce the chance of damage to the rotation mechanism under high winds.

I was thinking it had something to do with wind, however I had absolutely no solid idea what it was for.

And did they drop it because it messed up the gear rotators? Or something else

This is just a guess but it's probably a reliability thing.
