I need help configuring the AFF for my speaker-system.
What I need:
A 12dB(24?) crossover at ~ 550Hz.
A low frequency shelf (set one to boost ~ 4,5-5 dB from 180-190 Hz and below.
A high frequency shelf set for a gradual boost from ~ 2 dB at ~4,5kHz to ~ 8+ dB at 10kHz and beyond.
Is this possible?

Give a visit to the site of Siegfried Linkwitz. Very good staff about equalized crossovers.
Good luck,

THE filter-engineer writings to other engineers...
Playing around with "filterpro" finally gave me some useful numbers, implemented here.
The 20-turn trimpots were useless for finding suitable levels, removed and connected 20k stereo-pots instead.
It works!
If I now please could have some help making a low-lift, and a high-lift shelf...

The high pass and low pass are the same values, you just plug them in the appropriate spot on the board. Sorry if I forgot to put that in the manual.
I used the equal component value convention, the "Tina" calculation is probably for unity gain, which gives different values all around.
The calculator just gives you a starting point. You really need to measure the drivers in the application, calculate values, simulate, tweak, repeat.
