Dirac bass control not fixing peaks and nulls

[hardcore_gamer99]

I also tried to bump up frequency range 20 to 36hz by 6db and decreased peak at 42hz by 6db then saved filter but still REW shows same curve exact though i can hear now more SPL in low end. But rew showing up same curve. with dip and peak

Bumping up bass frequencies dips is an iffy proposition and very often does not bring anything to the table. For my HT (two subs) I did try to bump up the sides of the nulls to make them more narrow but kindof meh for me in my setup in my room.

Like you I did measure, but also listen.

That is a pretty big dip. Seems you have a room or placement issue. I'd start with adjusting the location of the speakers.

Cutting a peak is usually not so bad, but I agree, increasing in an attempt to smooth a big dip usually does not work. I had a crazy null like that when I had a square room. I ended up moving the listening position to mitigate it, but you could walk around the room and easily hear the spots where the nulls were.
