Modifying passive crossover components to offset EQ?

[CommanderZero]

I have a pair of klipsch satellite speakers (quartets) that I would like to repurpose as speakers for my gaming PVM. They have to be heavily EQ’ed to sound right and I was figuring that was EQ’ed the way it is by design since they were supposed to be surround speakers. I have the lower end and higher end EQ’ed pretty high with a dip in the mid. Is there some way I can modify the components on the crossover board to offset the need to heavily EQ them? Attached is a picture of the circuit, except for one coil that I can’t find the value for. Thanks for your help!
