    Hi/Low Pass Filter Settings

    Set up my gain using the JL Audio tutorial's test tune method. Now my system sounds flat and I can barely hear the sub. I played around with the crossovers, but not sure that I have gotten the setting right. What should I set the amp's hi and low crossovers at based on the speakers capabilities? Thanks in advance for the help and LMK what other info you need to help me out!

    Amp: Eclipse EA4000
    Adj Hi Pass 18 dB octave: 30-500 Hz
    Adj Low Pass 18 dB octave: 50-500 Hz

    Front Speakers: 5 1/4" Infinity Kappa Component Speakers
    Sensitivity 94 dB

    Frequency Response: 55 - 25k Hz
    RMS Power Range (Watts) 2-85
    Peak Power Handling (Watts) 255
    Impedance (Ohms) 2

    Rear Speakers: 6 1/2" Infinitu Kappa 3-way speakers
    Sensitivity 90 dB at 2.83 volts
    Frequency Response 45 - 22k Hz
    RMS Power Range (Watts) 2-75
    Peak Power Handling (Watts) 225
    Impedance (Ohms) 4

    Sub Amp: Kicker mono ZX 400.1

    Re: Hi/Low Pass Filter Settings

    Try this.


    Front speakers: High pass @ 80 hz
    Rear speakers: High pass @ 100 hz

    Subs: Low pass @ 60 hz

    If you have a Sub sonic filter: 15 hz


    Start there, and make minor adjustments to taste and listen for speaker, cabinet or mount distorting/sounding bad.

    Raising the HP crossover point on the front and rear speakers will give you more power handling, reduce low frequency distortion (in the main speakers) and generally get louder. Downside is you may be cutting off frequencies that are not being played by either your main speakers or subs. Creating a "whole" in your sound and make your subs not blend as well with your system.

    Lowering the crossover point on your main speakers will improve fidelity and bass output of the main speakers and blend better with the subs. Downside is your reducing power handling ability and increasing low freq distortion in them at higher volumes. Low freq resonace of the door skins becomes more apparent.

    For the subs raising the x-over point improves your mid/bass performance and takes more stress off the main speakers to perform at those frequencies. Downside it makes them more directional. You will notice the sound comming from the rear more and they won't blend as well into the system. It also increases the resonance of the sub box and you will "hear" the box "voicing" at lower volumes. That's bad.

    Lowering the subs x-over point makes for tighter cleaner bass that is less directional and is easier on the cabinet. Downside is your putting more stress on the main speakers to perform more bass duties and creating a whole in the sound that won't let the subs blend as well into the system.


    You want to find a compromise between these extremes that sounds best to you in your car with your gear.

    :facepalm:

    Did you read what I posted above?


    You don't use a LPF on mid/hi speakers. LPF = Low Pass filter. It allows the "Lows to pass". It blocks the highs. That's bad.
    You want a HPF = High Pass filter. It will block the sub/bass from distorting your mid/high speakers.

    Subwoofers use a LPF (allows the "lows to pass"). Mid/high speakers use a HPF (allows the "highs to pass").
