Im just curious about a passive crossover concept. Say you have a regular component set, that has 4 ohm drivers... When they are attached to the crossover, does the impedence get cut in half becouse they are running in parellel, or does it stay that same becouse the frequencys are divided.

It stays the same becuase the frequenices are divided. What the components in the passive crossover do is increase the impedance of that part of the circuit at the frequencies you don't want that driver to play. For a tweeter as the frequency goes down the impedance of the circuit goes up. The opposite is true for the mid. So when you look at both at the same time at low frequencies the circuit for the mid (including the mid) is roughly 4 ohms, the circuit for the tweeter (including the tweeter) could be many hundreds of ohm. So the overall impedance is still 4 ohms. Closer to the crossover point the impedance may dip down below 4 ohms when neither one has really started to rise in impedance.
