  • Bass trap for a car???

    Is it possible to break up the resonant frequency of a car's "cabin gain" frequency tone? Some frequencies just have a boomy drone tone that are annoying in my car. Sometimes it's my music but mostly it's a car behind me slamming 2 15" subs and it booms in my car at a specific frequency (so annoying). Any way to neutralize the cabin gain effect in a car? Small bass traps?

    Not passively. Use a graphic or parametric EQ.

    You're not hearing the subs per se. You're hearing the resonant frequency of the enclosure, the enclosure being the car.

    Open the windows.

      The most effective way to reduce external noise into the automotive environment is to:

      1: Dampen panel resonances using tiles of heavy material (think dynamat).
      2: Use a mass loaded barrier suspended on a layer of foam.
