With multiple things in parallel, the impedance can never be more than the lowest one at each frequency. It gets progressively lower with each additional load.
Crossovers alleviate this though, since they divide the frequency ranges up between drivers and raise the impedance in out-of-band areas for each one.

Matt,
Ok, so I don't have to worry about it too much. I came from car audio where if you put too low of impendence on the amp you blow it

That's still an issue with home audio as well, but once you get the proper passive crossover on the drivers the overall impedance should rise to an acceptable level. The simulator is showing what you asked it to: with the 3 drivers connected in parallel with no crossover, the impedance is going to be low.
Its still pretty low with a bunch of the crossover components. I am replacing mine with library ones that should have a better balance than what I made. I'll see what it looks like in a bit
