Dirac bass control not fixing peaks and nulls

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.

Several years ago, I had built an 8 cf enclosure for a 15 inch subwoofer. It was placed in the center of the living room and used as a coffee table as well. I still remember its smooth low frequency response. Of course, it was well designed but this smooth response was also not affected by room gain.

IMO, the center area of a room location is the best spot when you can do it, especially for an audio system using only one subwoofer. It's worth a try!

i dont have space so can put in front only but i am worried about 23 to 36hz area a bit of dip i wish could smoothen it

i have square room

Square room is tough. You might need some treatments, basic bass traps for the corners if possible.
