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!
