A New Crossover for my new JBL 4726A

[bannani]

I received my first JBL of my life, it is 3 JBL 4726 A. I choose thos for my hometheater place. I just plugged it, and I found the sound is too crispy, As I saw the crossover, I took one step rear, This crossover is very simple and look crappy. Can you help me to elaborate a very efficient crossover to make the most of those JBL if it is even possible.
Thanks all

Hello bannani, welcome to this forum.
I am sure you will have plenty of input here.
As I told you of the home-cinema french forum I think your best bet would be to copy the N3135 network from the 4435 (leaving alone the second woofer output) rather than the N3134 from the 4430, your 2206H having a sensitivity simlar to a 2234H.

But there is another issue you will have to deal with: the 2426 in the 4726A is a 16ohms version, whereas the 4430/35 have 8ohms versions.
