    jbl 2426 passive equalization

    Hello everybody,
    i have just found this excellent forum,
    i hope that somebody may help, as i have a problem with my passive networks!
    actually i have 2426h drivers, mounted on 2391 horns(with lens) for the mid frequencies, and a jbl E110 8ohm for low medium
    i have a 2405h as super tweeter...
    the extreme low frequencies are dirved bi amped with 2 15" woofers...
    all of this is installed in an original Jbl 4350 cabinet...
    my main worrie is that the crossovers i make never sounds good!
    actually i always have the same probvlem with the 2426, it has an annoynig resonnance around 2.5k to 3khz...
    i used a new 18db octave filter with a compensation for the top octave (with 43micro farad capacitor) but nothing works!
    i still have an irritating sound...i really can't manage to make those 2426 to sound correct...
    please could anybody help me find a way to equalize them ? is that a common problem with the 2426h??
    thanks !

    Welcome Vince!

    Your Driver was used in the 4430 and 4435.
    Despite there was a complete different combination you can try the HF Part of the Xovers.
    Maybe you suceed with some tweaking.

    Maybe this can help too. But it is for the 16 Ohm Version of your Driver.
