    Im looking for a portable lowcut filter to be used between my amp and a 2x10" cab that tends to break up when pushed too hard. Id like an unaffected (by the lowcut filter) signal to go to my 1x15".
    Any suggestions?
    What should I look for?
  2. Does your amp have a crossover function? Might be hard without that, assuming you are planning on doing it after teh power amp...

    You could wire a capacitor in line. That'll give you a 6db per octave low cut filter, also known as a 1st order low cut filter. Tell me the impedence of the cab and what frequency you want to cut at.......

    Yep, if the filter is going to be after the amplifier, this is the only way to do it.

    Just be aware that 6dB per octave is actually a pretty gentle slope. A vented cab typically has a 24dB roll-off. Keep this in mind when choosing your cut off frequency. You're better off going higher than lower.
