I would appreciate some advice on how to proceed with equalization of my sub. I only have two filters applied - one at 36 Hz and the other at 47 Hz. As you can see it looks as though I made the dip at 63 Hz worse. I've tried various filters on the 63 Hz frequency but nothing seems to affect it. I assume that means the other filters are the cause, but both are very narrow (setting of "5" for bandwidth). Thanks in advance.
