Anyone wanna help me do a cross over design? Measurement files attached

If you try mine, you can use it without the RLC on the tweeter it seems.

Ya, I was looking at that. What frequency were you targeting with that notch? Would a smaller R help make it effective?

Brute force, 17 components. I included a three component trap for the resonance at 17KHz.

Most of the components are on the tweeter, but they're really small values.

That's a winner. Hows the impedance etc look? I'm on my tablet till the 13th

I added impedance and transfer function plots to the post above.

I doubt the tweeter can handle a low crossover, but if you are adventurous you could try this: cross at 1700hz with a cascaded BW1+BW2 filter on both woofer and tweeter. Pretty sure the tweeter stays positive polarity. Intended for horns where the tweeter is 1/4 wavelength behind the woofer at crossover, and provides a third order roll off with LR lobing behaviour.

Nice.

I started along that route and wandered off, but you've done a great looking job with it.

Nice one Pete. I don't have PCD right now but will look into it later. Looks like there's a notch on the woofer at 900hz? How expensive is that

The woofer circuit is 5 components.

Before the XO, I have a parallel RLC consisting of 1.2mH, 22uF, 9.1 Ohm, followed by a low pass consisting of .9mH and 27uF.

The tweeter has a parallel RC before the XO consisting of .68uF and 18 Ohm. Then a HP section consisting of 2.2uF and .12mH.

Then, the fun begins. In parallel with the tweeter are three separate series networks.
1.8mH, 2.8uF, 10 Ohm (impedance compensation)
.11mH, 12uF, 2.5 Ohm (pass band EQ)
.05mH, 1.2uF (HF resonance notch)

Wow lol. Only 2 bigish coil, so it won't be too expensive
