Thanks for that, it was very informative. But now to add:
As you said, white noise would have equal power at every frequency. So lets say X watts per hertz. If a two way speaker has a crossover at 5kHz, which is at the high end, then the woofer would receive just under 5,000 times X watts, whereas the tweeter would receive 15,000 times X watts, or three times the power. If the crossover was at a more normal 2.5kHz, then the tweeter would receive seven times the power with white noise.
But white noise is not a good example for the real world. Pink noise, with the crossover at 2.5kHz, would have the tweeter receiving the power of about three octaves while the woofer would receive the power of about seven octaves. So the woofer is indeed receiving more than twice the power.
Your research showed a power midpoint of around 600 Hz, whereas pink-noise would have a power midpoint near 660 Hz, so pink-noise might be considered not far from the real world.
So I stand corrected: The woofer might be expected to receive twice to three times the power of the tweeter in a real-world two-way system.
Am I off-topic yet?
