Hello everyone, I'm french and I do not speak too much English, but I find this forum very good. I just bought a system of jbl year 1995 and I need your help.
the system that consists of 2 jbl subwoofer with 4745A VHF (2x2404h) option (1x2445j) "i have 2445j or 2446j two possibility" (2x 2206h)
then 2 boxes jbl 4755 (2x2226h)
the filter is 4-way active jbl DSC280
to amplify the system I have two audio amplifier crest 8001 (4x1200w)
low for 2226 and 2206 sub
and an amplifier dynacord pca2544 (4x500w) for high and vhf section
my problem is to parameterize the filter dsc280 this is where I need you

What should I put as cutoff frequency in 4 ways?
what delay?
what gain?
what etc etc ..... for the system sounds strongand clean ?

thank you very much for your help
and sorry for my english
