i tried 2k xo in xt1086 horn, i compared that to nsd1095n in same xt1086.
at 5k i use funktion one horn, dont need much eq crossing 5k

you could try different amount of resistors if dsp is not available

now we messed this up, i still wouldn´t compare de25 to de250

I have measured, my system, but only frequency responce and impedance, and it is very clean. It has an huge impedance peak around 1600Hz though. I guess it is the Fs. So it might be to much to ask of this driver to cross at 1700Hz.
We should not mix this up in you tread, I am only interested in you listening experinces.
But If I could just ask manninen, how was the result comparing DE25 with nsd1095 in you xt1086 horn?

(I can find out of that with my eq) But maybe it is because of what happens lower in frequence. What horn do you use?
You need at least 12dB electrical, if you want to cross over that low, 18dB is minimum. The driver will make too much excursion and will start to scream at a certain level.
