This combination of drivers seems to be screaming out for different amplifiers.

I see little point in creating an 8ohm passive crossover for two drivers that are so mismatched by such an amount.

Fusion, you have a lot of persons here trying to help you. Good idea to listen to them. Andrew's post seems to make the most sense at this point.

Hi,

That doesn't make any sense. It might if you wanted to run the treble
off a flea powered class A valve amplifier which it does allow you to do.

Otherwise the tweeter sensitivity makes no difference
to the arguments regarding active and passive x/o's.

rgds, sreten.

It makes some sense to me.

Where did active come from?

I never mentioned it.

Hi,

"I see little point in creating an 8ohm passive crossover"
implies using an active x/o instead. What some sense ?

rgds, sreten.

It it was me building the "Standard Econowave" I would
redesign the treble x/o section for higher load impedance
than 8 ohm, say 22R, and put most of the attenuation
at the front end of the x/o, meaning low power handling
requirements for the rest of the components.
A way of using to advantage, the high tweeter efficiency.

Does having two woofers in series have any advantage or you r looking at the crossover and BSC only side of the equation.(?)

Hi,

I don't understand the question. What I mean is if you know your going
to attenuate a mid / tweeter a lot, doing it between the x/o and driver
with a high power 8R L-pad is not the best way to do it.

rgds, sreten.

Default HF attenuation

I don't get the down side of excessive tweeter sensitivity. Sreten suggests a better way to deal with this potential advantage.
