That image is very small. It's difficult to see the component values. No big deal, I was just curious.

LeifB60 pls give the pic of the filter which we can read...i will try it at home..,i have ALp 12 which is apsolutelly unlistenable..i have lost 7 years with this driver..
driver alone is not for listening at all...
i'm playing with the filter, 2.5mH //20 ohms for the start..
2.5mH // 6.8R is too sharp still for me..
LeifB60 for what is the parallel notch filter (60+33nF+2.43mH) i have checked in simulator.. doing something around 20kHz?

driver is mounted in KEF LS50 -like cabinet.. cca 20 liter.
2.5mH 0.1ohm bobbin is made from thick wire and double C cores with air gap..
i'm thinking to make Fostex 3"- Alpair 12P combo, where Alp. would be only for bass.. Fostex 83 SOL regardless of size, sounds much better.. more normal, not so irritant like Alp 12p
