Frequency response issue.

[Fyrewyre]

Hello again everyone. I was just running some tests today on my dual 15 titan cab and as i was playing a frequency sweep from 20-120hz (with all dsp processing off) I realized i have a dramatic dip in the 40-60hz range. It is actually quieter than the 25-35hz range. Is this a room issue with cancellation perhaps? is there anything I can do to remedy the situation?

Walk around the room and see if it changes in different locations. Tell us a little about the room (size, shape, etc.) and sub placement.

If it's not the room, check again for leaks.

A dip centered at 50 Hz indicates either the sub or the mic position is roughly 6 feet from a boundary.
