Hi, I have 4* 6,5" co-ax speakers that will be used in an atmos celing setup. The original crossover has a donut shape that is to big to fit in the cabinets so i need to copy the layout to a smaller form factor. I will might upgrade the components at the same time.
The original crossover have a "Boundary switch that can compensate for placement near a corner or wall, this feature do I not need.
I'm a newbie so do I do need help how to make a similar filter without the boundary switch, and wich components to buy (or use existing)
I'f anyone could make a skethc that I could use to wire and solder I would be extremely grateful.
Have attached pictures and a sketch attemting to trace the circuit board, but am not confident I got it right ..
Thank you.

Thank you very much for your reply.
I attached a new drawing based on your input to verify that I understand this correctly, does this look ok?
So this is a second order / 12dB filter with the two resistors used to dampen the tweeter?
Sorry for asking obvious questions, as a mechanical engineer I find it annoying that i still do not understand more electronics despite all the obvious similarities with mechanical equations....

Are you more comfortable with mass/stiffness based resonances?
The tweeter appears to be second order. The top resistor is likely there to reduce the level.
The woofer may be first order tending toward second. The lower resistor probably damps that, while the RC would reduce the rising impedance.
An inductor/capacitor resonance is the same. The mass/stiffness resonance simply uses pressure/velocity to replace Volts/Amps.
Yes.
