The issue is I have wired to the amp and The pre-outputs from the receiver (Yamaha A-3060) are being split with two SVS SB13 Ultras. Because of that and as far as I know I can't adjust the frequency filter on the fronts without affecting the subs. I want the Logan's cut off at 45-50hz. This way I can still utilize the P.E.Q. in the subs.
