Change crossover EQing?

[thepentium]

Hey all..

Got an interesting, but noob, question...

Ive got my tube guitar amp running into a JBL mp215 PA cab, and its sounds killer, my biggest annoyance is that there are some different notches and bumps in a guitar speaker that dont exist in a PA speaker.

Is it possible to change the crossover to adjust to some of these notches and dips?


Obviously you can only do so much, but some of the bigger differences would be nice to get close.

Here is the frequency response of the speaker right now:


And the guitar speaker that I'd like to match is a G12T-75:


Thanks for your help, this will help me out a lot!
