3omhs speakers with 4omh crossover

[swagg1ns]

Hi! I'm fairly new to building sound systems and have some questions regarding crossovers. So right now I have 3omhs hertz 45-4.5k Hz (https://www.brl.se/sv/artiklar/hertz-mp-253.html) as midbase speakers in my doors and they are currently and some fairly cheap 100-20k hz speakers at the window. The problem right now is that the midbase speakers gets all the frequencies above 60 and the only way I can see to solve this is by crossovers. I've been thinking to pair the midbases with some 4ohm hertz tweeters 1.4k-22.5khz (https://www.brl.se/sv/artiklar/hertz-mp-253.html) and I was stupid enough when I first bought the system to choose a 3ohm spekers so that leav me with yet another problem... If I pair the speakers with a 4 ohm 2 way crossover, 3.5k split (https://www.ljudia.se/produkter/tillbehor-bygg-sjalv/delningsfilter/2-vags/sinus-cr-235-3500hz) or 3k split (https://www.ljudia.se/produkter/tillbehor-bygg-sjalv/delningsfilter/2-vags/visaton-hw-2-70-ng-4ohm) the midbase speakers will mess with the crossover and the lowpass will split at a lower frequencies (*0.75?) if I've get it correctly? That would mean that there would be a gap of frequencies between 2600 and 3500hz with the 3.5k crossover.

Is there anyway to fix this with a fairly easy sulotion or do I need to buy new midbase speakers?

Best regards a noob.
