I opened up this speaker and saw a capacitor and a choke. So, my first thought is that it was simply a first-order Butterworth filter. But, while the capacitor is placed in series with the HF driver, as expected, it is also part of the LF circuit. For the LF driver, the capacitor and choke are connected in series, and that circuit is placed in parallel across the terminals of the LF driver.
Can anyone help me understand what the function of this circuit is and where I can find the math?
Thanks!
