View Full Version : Passive crossovers or Amps built in Filter?

03-24-2011, 05:06 PM
I have a set of Hertz ESK 165's and Esk 130's that came with passive crossovers. I will be powering them with an Alpine PDX-F4. Should I use the passive crossovers or the amps built in high pass filter? If I use the amps filter will I still need passive crossovers for the tweeters which are separate from the drivers?
