Upgrade from WIlson Sabrina

Sid…your 244 traps are full range. They are on the wall behind speakers and are not in the corners. You still have your corners accumulating bass and you still have standing waves. Your GIK panel placement is not effective as far as bass traps go.
What I was talking about is GIk tri traps with limited range. They go directly into corners and eliminate that extra space where bass accumulates, in addition to trapping bass and not affecting high frequencies. 
Your 244s will be more effective at first reflection points but don’t do a lot for bass trapping. 

I have an even smaller room at 9x12 and I've crammed my Sopra 2's in there and also have had some bass node issues. I know your room is treated, but upgrading to actual bass traps helped me. I have 4 on the front wall, stacked floor to ceiling. The second set really did help with imaging and bass control. Not sure if you have concrete or wood floors, but with wood subfloors I was getting bass feedback like crazy so I purchased Herbie's footers and they have helped calm the bass quite a bit and now have much better imaging. I'm looking at other options to take it further now. I'm sure a new sealed speaker will probably help, but these small and affordable tweaks definitely helped solve some of my issues and made my listening experience better in the bass department as well as imaging and detail.  Good luck. 

you need two of these for each corner floor to ceiling 

@j-wall exactly what I’m telling Sid as well. Those 244 aren’t actually corner bass traps. 

Let's fill your small room with more stuff; that'll definitely make the room bigger and solve the problem!
