Correct. Those are pretty much the DTAC or "Doorknob" capacitors. FWIW, I looked up Wima caps at one point, and they also make a

If you're using ARTA just set your time marker and take your measurements for both drivers, then use the measured phase. You don't need to extract...

But any program that yields a flat response with a high order roll-off will sound poor in a car with its cabin gain. It is possible to design it with...

Your impedance is sitting about 2.5 ohms at 90 Hz. For 4 ohm nominal, my own best fit dips to no lower than 3.3 ohms. I think yours will tax some...
