I want to add a hi pass filter between my old amp/ preamp, cause I would like to use a powered subwoofer.
I would like to block about 100hz from my preamp to the power amp.
I see there are bass blockers for about $25 that do what I want.
I like to know the value of the capacitor needed to block the lows.
Thanks

Thanks, the fmod units are just what I need, with 12 db slope, 6db would be to soft. I was thinking just using a cap and save some $$.
