Thanks jagman!!
I check everything and its fine, remeasure and the dip at 65 still there,, it doesnt make any sense to me every time I apply a filter to the 65 dip, it doesn't change much
even when the gain is 8 or 10, I'm just going to ignore it
I look at the graph LF1 (SVS sub) and the dip is about 68hz.
