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


I guess this is relatively common in listening system. Is there any way to smooth this out so I get more bass energy at my listening position? This happens with our without my 2x 18 inch subs. Room is 12 x 16 x 8 ft, speakers 4.5 ft apart on long axis and I am sitting 4.5 feet away. I tried moving back and forward but the entire middle center of the room except near the walls has decreased bass.
Is this a boundary effect or could it be due to bass cancellation effects?

The best success I have had is using the Vandersteen speaker placement calculations for the main speakers.  This is available on their website.  I have two subs.  I have 11 acoustic panels, diffusers and traps.  I can walk around my room and the music sounds good.  It was not that way at all previously.  Several peaks and nulls. Good luck.
