Maybe these links helps:

i want already created config files.
And you can try my simple EQ APO config(IEM's):
Copy: 1=L 2=R 3=L 4=R 5=L 6=R 7=L 8=R
Channel: 3 4
Preamp: 20 dB
Equaliser: Generic
Filter 1: ON LP Fc 100 Hz
Filter 2: ON LP Fc 100 Hz
Channel: 5 6
Preamp: 0 dB
Equaliser: Generic
Filter 1: ON HP Fc 100 Hz
Filter 2: ON HP Fc 100 Hz
Copy: L1=L R1=R
Channel: L1 R1
Preamp: -10 dB
Delay: 0.6 ms
Channel: all
Preamp: -2.6 dB
Copy: L=L+R1 R=R+L1
In the first line I get the stereo L R signal distributed to all eight channels 1 -8 of my soundcard
In the following two sections I make a low pass and high pass, I use the Butterworth filter twice to get steeper slope.

Last link in my post leads to few ready to use LR crossfeed scripts.
Channel 1, 2, ... are same as channel L, R, ... etc, so you don't need to copy those. https://sourceforge.net/p/equalizerapo/wiki/Configuration%20reference/#channel-since-version-08
Do you mean 2-way crossover with crossover frequency set at @100Hz (instead of crossfeed as in your subject says)? https://sourceforge.net/p/equalizerapo/discussion/search/?q=crossover

What do you mean Channel 1, 2, ... are same as channel L, R, ... etc, so you don't need to copy those.
Copy: L=L R=R C=L SUB=R RL=L RR=R SL=L SR=R
should i use this instead of this
Copy: 1=L 2=R 3=L 4=R 5=L 6=R 7=L 8=R

Check the Wiki link I gave.
Synthax "Channel: 1 2" points to same channels as "Channel: L R" so, you don't need to define these channels (i.e. Channel: 1 and Channel: L both points to front left channel, Channel: 2 and Channel: R both points to front right channel).
As there are two ways to point to each channel; a number and an acronym which of the latter mappings are constant ... so, "Copy: 3=L 4=R 5=L 6=R 7=L 8=R" should work as intented as long as you have all 8 channels enabled. Synthax "Copy: C=L SUB=R RL=L RR=R SL=L SR=R" would be my choice.

OK THANK's to YOU @Juha for helping me..
Perhaps this is helpful. Peace (interface for Equalizer APO) has Linkwitz-Riley and Butterworth filters. No need to come up with the correct Equalizer APO commands according to the order of the filter. Just select such a filter under an equalizer slider and entering an order value (up till 100 order, a brickwall filter)
@Peter Verbeek i didn't no that option has in Peace(interface for Equalizer APO) and thanks for reply i will try it. Let you suggest Best Crossfeed (Jan meier or Chu-Moy or LinkWitz) I have IEM's Headphone's( https://www.blitzwolf.com/BlitzWolf-BW-ES2-Dual-Dynamic-Driver-In-ear-Earphone-Headphone-With-Mic-p-192.html) and (5.1) Speaker's system with Subwoofer(4800W) in my home. i will see lot of Movie's and Listening to Music.
On the Effects panel of Peace the Jan Meier and Chu-Moy crossfeeds are available. But they are an approximation (simulation) since the Equalizer APO filters can't precisely produce these crossfeeds.
