Frequently Asked Questions (FAQ)


  • • Why do my midbass drivers have very little bass output?
    Weak midbass is often caused by incorrect crossover settings or poor door sealing. Make sure the speakers are mounted securely and the crossover is adjusted correctly.
  • • Can I use these without separate tweeters?
    These drivers are designed to reproduce midbass and midrange frequencies. For full-range sound, they are best paired with compatible tweeters and a proper crossover.
  • • Why do the speakers distort when I increase the volume?
    Distortion usually happens when the amplifier is clipping or supplying too much power. Proper gain adjustment and amplifier matching can help maintain clean sound.
  • • Do I need an external amplifier?
    Yes. An external amplifier is recommended to provide the power needed for strong midbass performance and better sound quality.
  • • Why do my doors rattle when the music gets loud?
    Powerful midbass can cause loose door panels and trim pieces to vibrate. Adding sound-deadening material and tightening the mounting hardware can reduce unwanted noise.
  • • Can I install these in my factory speaker locations?
    Yes, if the speaker size, mounting depth, and available clearance match your vehicle. Some vehicles may require adapter brackets for proper installation.
  • • What is the best crossover setting to prevent these midranges from blowing at high volumes?
    You should configure a High-Pass Filter (HPF) on your amplifier or crossover set no lower than 80 Hz to 100 Hz. This blocks low-end bass frequencies that cause excessive cone excursion and potential mechanical damage to the cloth surround.
  • • Can I use these with a subwoofer?
    Yes. A subwoofer handles deep bass while the midbass drivers reproduce upper bass and midrange frequencies for a more balanced system.
  • • Why do the speakers stop playing after a while?
    An amplifier entering protection mode or a loose electrical connection can interrupt playback. Check amplifier ventilation and inspect all speaker wiring.
  • • Do these speakers need a break-in period?
    Yes. Many users notice smoother and more natural sound after several hours of normal listening as the suspension becomes more flexible.
