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

Springbok, amplifier do use zobel network but it purpose is to stabilize current rail that supply power to the output stage during speaker loads. Using a zobel network in the woofer help sustain a near pure resistive load.

Just tested the network today and notice an improvement in the midbass. As of now, midbass sound punchy and articulate. Their seem to be more control on the cone but I can't conclude on this since the components are not fully burn in.

Thanks

Thanks for the responses. Gregm, judging the speakers T/S parameters, the impedence is up to 28 ohms at the crossover point with is 2500hz. At the point where the the impedence start to rise is at about 350 hz. At 1k, it has risen to 16.30 ohms.

So far I have the resistors but I'm still need the capacitors but don't with one to go. Electrolytic or poly caps?

Thanks

The electrolytic is non-polarized. Sorry about the mis interpretation. Polarized electrolytic is a no-no. :)
