midrange trouble?????

I am building some transmission line speaker and am well into the process, I have aquired some high quality military caps and inductors for the linkwitz-riley crossover but it will boost the midrange by 2db, how can i add some sort of equalizer to even it out, I have access to high precision resistors. woofer 93 db
midrange 92 db
tweeter 92 db
2nd order link/riley Xover
