Question about Zobel networks

[Chazb11]

OK, I'm not trying to start a debate about the usefulness of Zobel networks. I know there is a lot of debate about them already and have decided to try one to satisy my own curiosity.

I found an online calc to easily determine the values for the cap (in uf) and the resistor (in ohms) but it doesn't mention what voltage value the cap needs to be, or wattage for the resistor.

The woofer I'm going to try this on is rated for 100 watts and I'd like the zobel to hold up to that, even though I would rarely drive my system over a couple of watts.

Thanks for any input. :thmbsp:

I think a 100V cap and 5W resistor will be a good starting point. How did the calculator know what network works for your driver? Did you have an impedance plot available??

100V cap and a 10W or higher wirewound resistor should be fine. I've used 20W non-inductive types in PA networks before.

You input Re and Le. Too simple???

Too somple?? Nope, Re and Le is what you need. So it sounds like you had that.
