Hello there, I have a question concerning using a BFD as a low pass filter for my sonosub. I have a HK-3485 which gives a full signal subwoofer out and that gets passed to my ep2500 to power my sono sub. Is it possible to get a BFD and add a filter to use it as a low pass at 150hz without using a mic to test for SP? I did plan on eventually using the BFD for EQ just dont have the time to figure out how it works and was curious if I could use it as a low pass filter until I got the chance to properly set up the BFD to do EQ and low pass at the same time. Thanks!
