    hi everyone..

    heres the situation i want to make a low pass filer for the subwoofer i am making

    basically at the moment i am running the equivalent of a positive and negative rail into a speaker (driver) but for left and right channels from the audio output of my hifi

    will this be sufficient with the lowpass or will i ned an amplifier as well

    i think the formula for the pass is f=1/2piR or something similar !?!? i tried looking it up but im confused

    i want a frequency of about 40-60hz (is this right)

    anyone here in a good mood and feel like helping with the resistor and capacitor values !!!

    and maybe help with a very simple amp construction

    sorry if the above is a little unclear.

    many thanks!
