I already have a 200 hz second order low pass for the Eminence Alpha 15a. using a 68uf cap and a 9mh inductor. But I want to try a first order low pass at 80hz. Off the top of my head I figured I would just need a inductor of about 20 -25 mh. But low and behold when I ran the calculator here it said for a Bissel at 80HZ all I needed was 11.7 mh could there calculator be in error ?
