Workbenches should be providing coverage to EVERY part of your base inside the walls, which only allows enemies to spawn outside of the walls.
That's what the walls are for, to give you a first defense against event raids.
And no, the only predetermined spawn points are the actual, physical spawners that you'll find in Black Forest (Greydwarf spawners), Swamp (Draugr/Skele/Surtling), etc.

Edit: Forgot to mention that when you're raided, you should always move outside of your walls so as to prevent a section or 2 being broken and enemies flooding in. The protection they provide should give you enough time to react to a raid and move outside of the walls, pulling the enemies to concentrate on you instead of your base.

Yeah I've placed workbenches to where their radius' overlap. And thats exactly the approach I was hoping I would be taking. To have an event trigger, and then rush to meet them on the outside of the walls. Yet every single time, I catch the event text popping up on my screen, so I rush out from wherever I am to find them already b-lining for my animals, and of course when its Trolls they seem to already be on top of them.

I just don't even know at this point -.-
