Zobel network

Having to build my own crossover, I have come across to tweak my crossover by adding a zobel network. From my understanding, a zobel network helps flatten the impedence curve of a speaker to nominal. With the impedence curve flat, the phase of the speaker comes close to in-phase or 0%.

Since this tweak is very simple, does anyone know of anyone of any speaker company that uses this network or have modified a speaker with a zobel network?

Thanks

Alfredo, use the cheapest caps to determine the optimum value. Since you're nearly (already?) there, one way of "burning in" caps is to charge and discharge them (outside the circuit of course) with ever increasing voltage until you reach ~90% their nominal value.

Alfredo, are there gross anomalies in yr woof's impedance curve around the chosen x-over point that necessitate a zobel?? If not, live with the woof's inductance pattern. If yes, you're stuck with it! If you're adventurous, try the zobel both in front and behind the xover & choose the setting you prefer...
