I think his thoughts are valid, the equal power point being 350 Hz, and my limited experience says that the wider the spread of the midrange the better the overall sound.
I would favour a much lower X-O, a full octave lower at 250, and bi-amping I generally use 120/150 Hz.
This is expensive when using passive .
i have always thought that commercial speakers used higher X-O points merely to save money on copper in the inductors.

Rarely in a bass/mid/high or bass/high speaker system do you ever see a crossover below 500hz.

However, we also see many modern speakers that crossover in the 150 to 350hz range. That is because those speaker are not standard bass/mid/high configurations. They are typically sub-bass, bass/mid, high configurations.

The existence of external subwoofers, has lead people to the idea that the can build sub-bass into a single cabinet multi-speaker system.

Just an additional thought.

So according to Blue Wizard's graph, a the woofer to mid crossover should be around 500
hertz to allow the woofer to take that huge wattage load that occurs from 250 to 500 hertz?
Hi, No.

Linear power scales are very misleading. Scaling to dB completely
removes the "huge wattage load" and more to the point the graph
shows peak levels, i.e. clipping levels, not average rms power levels.
