SPL Range and SQ help

Long time lurker, first time poster here. I could use some help making the graph look correct. I can't figure out why the SPL side of the graph displays -45 to -15. Also I'd love to hear any suggestions if you see anywhere that needs attention in terms of sound quality.
1/6th smoothing has been applied. The photo shows my front stage, LFE channel and RMS average, post-Dirac.
Beyond that, does anything stand out as needing attention? For reference- this is for movies and music and I don't listen super loud but do love good strong bass. Thanks in advance.

Re: SPL range. Most likely your microphone does not have SPL calibration + you skipped the SPL calibration step in REW. If you want your SPL range to accurately reflect what was measured, you will need an SPL meter. Do you NEED an SPL meter? No, not really. It depends on what kind of measurements you want to take. If all you want to do is take measurements of the relative amount of bass compared to treble (as you have here) then an SPL meter is not necessary.

If you ask me, your system has way too much bass. But if you like it that way then ... it's your system, your music, it's there to make you happy. If that's what you like, IMO there is no problem.

First, welcome to the Forum!

We typically recommend graphs with a 60 dB range on the left axis; yours shows only 35 (-15 to -50). Changing the graph will make it look better and also better reflect what you're actually hearing. Post a new one back so we can have a look at it.
