Subwoofer Svs SB4000 Peq with REW and Umik

[vincenzo]

Hi, I bought a Svs Sb4000 subwoofer, I did the 50 hour break-in, and I started doing some equalizations using the svs app via the 3 bands of peq that are available. I am attaching the rew photos without smoothing before and after the peq. I would like to understand if this difference on the phase section is normal. Regarding the equalization is the curve obtained well? Is this empty at around 78hz solvable in any way? Thanks in advance

Ok, my concern is that by 10Hz you should be seeing the level drop and its not so something is not set correctly. Im not really a pro at using REW so hopfully someone will chime in with better knowledge on this.
