You could use active on the woofs and a simple cap on the fullrange.....if you hardwire your speaker wire to the cap and the cap directly to the driver you will get much better sound than using any connector. All speaker wire hardware ruins the sound. Hardwire.....please....you will love it. Please bypass the large value film caps with a great sounding .1 to .33uf. Make sure you orient the outside foil of all the caps toward the driver.
