Hi Hat,

This filter is the one you'll need with changed values if needed. I would start with that filter and listen while trying to tune the bass level to your room. The bass should be in the opposite phase compared to the AER driver.

If the bass is not going deep enough (no warmth) then increase the resistor value to 1.8k or 2.2k (whatever you prefer), this will bring deeper bass. If the bass is warm enough and the bass mids are too shy then you can reduce the value for the second capacitor (more mid-bass) or increase the value (less mid-bass).

While playing with the values you'll hear what is changing, with that info you'll be able to tune the system to your room/equipment.

These do offer a great starting point, but I'm interested in learning the
formula(s) used to determine the cap/resistor values.

I mostly use the basic formula 1/(2*pi*Fc*R) but listening to what you're doing works best.

Have fun!

Bert
