RoomFit question for our experts

[Djinn206]

I have done a room correction with RoomFit some time ago which I am totally happy with, but just noticed that there are 2 PEQ entries at 29 Hz, one with positive and one with negative gain. I am just interested if this can make sense?

Notice that Q-factor is different. This approach is sometimes used to modify the shape of the filter to make it a closer fit to the exact shape of the resonance.
IME this is usually a waste of filter bands, since perfect precision isn't really required for effective room correction EQ.

But it doesn't hurt either so I don't complain.
