Lots of bass at walls, lack of bass in center of room/listening position

@Smodtactical, I suggest you purchase a Minidsp. You have already invested a significant amount in your system. The Non-Hd version of the Minidsp is $100. The HD version of the Minidsp is even better and can do more.  

It  appears you are using REW and that is a good thing. REW will generate equalization filters specifically for the Minidsp. You then load them into the system via computer. There are videos on the web to guide you through the process.   

There is a learning curve to all of this. You are getting many suggestions all with good intentions. The bottom line is you have to experiment and learn as you go. Don't give up, and have fun on the journey.           

@smodtactical,

I have been down your path many times over the years. Experiment, experiment, and learn from others for sure. So many factors play into getting good bass response, and as others have mentioned, normally, it’s complicated to get even bass distribution throughout the room with room modes playing with your ideal settings and affecting the listening quality. I have learned to use the Velodyne SMS1 Sub EQ for my sub integration needs. Well, lately,  not much at all due to my new Classic Audio Loudspekers T1.5, which is in another post. 
Anyway, here are some views of my smoothing progress as measured at the center of the room, which is the new listening position with my giant speakers. You can see the initial response and after response. Playing with different frequencies, phase, etc., and given time, you will get a smoother plot.

 But, and I say this, do you really want a smooth bass plot? It’s sort of a rhetorical question, but if you want excited bass at let’s say, 50hz, you may want to visualize what it will sound like for you, in your room, with your equipment. I think smooth bass is okay for critical listening if your speakers need it, but not all speakers need extra bass. But yes, if they do, then add subs to help augment that portion of the musical spectrum that your speakers can’t reproduce. 
I find myself using subs less now that I have speakers with 18” downward firing bass, and 15” front firing bass. 
The room is a major component of your audio system. If you can, spend money on room infrastructure things such as sound insulation (Roxul safe and sound) in the walls, Quietrock sheet rock, anything that will assist with noise abatement that will inhibit noise and bass from leaving The room will greatly benefit your listening pleasure and bring peace to your family who do not want to listen to Aerosmith at 100db with a 50hz bass bump to feel the kick of the drum. I spot treated with absorbers, diffusion as needed after I listened and measured the room to suit my needs. Good luck on your journey. 

I had an issue with my room few years ago, bass was not filling up around my sitting area. Tried many ways to get them filled up by moving sitting position, speaker placement and I was even contemplating of getting a sub in. After I was introduced by Micahel Green with his Room Tune pillows and consulting him I did some placements of his room tune pillows in my room and finally presto bass is now more around my sitting position. Eventhough I'm not getting super low notes as I'm using bookshelf speakers but it was night and day improvement for me. 

Hey just made a discovery.

Just played around with the roon dsp, i hit invert on my left channel, and all of a sudden the bass came out of nowhere, was focused, intense and powerful and evenly distributed as I lean left and right. When you turn invert off on the left it weakens and becomes much more diffuse. So maybe i have something wired incorrectly? Only thing is if i leave invert on, i sometimes get some popping and crackling so sounds on the inverted channel.

Actually this seems to collapse my sound stage and squash imaging towards the center as well
