There is a ton of good info (both cross over and speaker design) to be found here:

My thinking is to agree with Defro - each driver has the 100 watts available to it (theoretically based on nominal 4ohm impedance).
This has always been my belief and I have yet to have anyone more skilled in passives than I be able to reasonably dispell or for that matter confirm that belief. [img]graemlins/dunno.gif[/img]

Just a few days ago I had a long discussion with chev2 about just the subject... I did all of the listening hehe
It seems that the xover shows the amplifier a constant 4ohm load... then each driver gets 50/50 of that power (assuming a 2way set).
Essentially, the amp can only send\produce one frequency at a time, therefore both of the drivers are always at the same impendance... then its the filters for each speaker that either lets the power through, or blocks/dissapates it.

If we were talking two identical drivers in parallel with no passive network and a current limited system then I would agree - each would 'get' half the power.
but, the entire point of the crossover is that it's own impedance changes with frequency to attenuate the frequencies outside it's bandwidth and have no or little effect on those within it's bandwidth. ie. a lowpass coil at 200hz should be totally transparant to a 50hz signal but very resistive to a 2000hz signal.

ya i think your right derik if your slicing hairs
the resistance would probably be slightyl different the compliance could be slightly different
the magnetic density would be stronger on the driver facing the lunar pull
