Hi all,
For fun and maybe for a build down the line I've been messing around with the Forsell EQ guide, and this calculator...

There's some good discussion here...

Plugging in different values into the calculator that I'm grabbing from NYD's schematic, the g-pultec, the available inductors from carnhill etc I'm getting wildly different values for the impedance of the different filters. What's an acceptable range to shoot for?
I can follow the equation for determining Q, but I don't understand how it relates to the impedance of an LC filter. Also in the white paper Forsell sort of leaves it at the Q being determined by the quality of available inductors. But like what's a real world, Q?
Thanks
