Hi guys I have a FBQ3102 and a peavey IPR2 5000 amp running two Dayton HO 18's one is sealed and the other one is a mini MARTY ported box. On the front of the EQ is a low cut and high cut filter. When both boxes were sealed I had them both turned to the farthest left. Know I have one ported sub how should I have those cut filters set for the ported sub??
