Hi, could you help me with the crossovers for my diy loudspeakers. I have a midbass Kartesian Wom120_vMS, 8 ohm, 120 mm https://en.toutlehautparleur.com/speaker-kartesian-wom120-vms-8-ohm-120-mm.html and Peerless DA25BG08-06 tweeters https://en.toutlehautparleur.com/dome-tweeter-peerless-da25bg08-06-6-ohm-1-inch-voice-coil.html .Enclosures are 5l. with 57hz. port tuning. My question is which order crossover should I use and what cutoff frequency should I choose, between two speakers?
as far as I know the best procedure is to measure the speakers in the planned enclosure and then simulate and develop the crossover based on measurements.
if you cannot or don't like to measure have a look at: https://www.diyaudio.com/community/...igning-crossovers-without-measurement.189847/

If i use this 2500hz, the calculator says
Capacitors
C1 = 10.6 uF
Inductors
L1 = 0.51 mH
And L-pad attenuation 5db to equalise sensitivity
R1 = 2.63 Ohm 11 watts
R2 = 7.71 Ohm 6.1 watts
Is that correct?

Midbass has some nasty peaking in 8-10 kHz area.
Tweeter has good Xmax plus higher power rating than midbass and its power rating will be increased by attenuation necessary to match efficiency of the midbass.
Taking that in mind I would go with fairly low XO frequency around 2000 Hz.
Thats some three times higher than tweeter Fs and some four times lower than midbass peak, so simple 2nd order will give enough rolloff to avoid any problems.

download jeff bagby's baffle simulator to simulate the effect:

designing a good x-over is a long but entertaining journey. first step could be to read through the thread i linked to in my reply #2!
