WebAug 16, 2011 · In truth, as much as I find Zobels generally silly I very frequently use a damped 2nd order network as a starting point on woofers. That is a 2nd order network with 0.5 to 2 ohms in series with the main shunt capacitor. I will not call it a Zobel because the optimization does not include flattening impedance. The R is not close to the woofer DCR. WebNov 8, 2011 · Re: Zobel Network Resistance Wattage question To answer your question, yes, a 20 watt resistor will be just fine in a zobel.

It's instructions are to prove the Z (in) is purely resistive for the circuit shown. Based on the fact that R=8 ohms and L =400uH, I have calculated C to be 6.25uF. WebResistors are most often used in "padding" a tweeter which is more efficient than the woofer, so the overall system frequency response will be flat. The resistor, in series or parallel with capacitors and/or inductors, is often used as part of a Zobel or impedance compensation network. A good Meter is the best way to "Trust, but verify"
