Seating height and bass

So my myriad of other threads seem to have me believing I have a null which explains the lack of low bass at my sitting position.

tonight I pushed the couch out of the room and used a chair instead. Bass was much improved but I realized that with the chair my ears are at tweeter height. Sitting in the couch they are several inches below the tweeter.

i stacked some books to mimic my height when sitting on the now displaced couch and started moving them closer to the speakers. I tried 6 positions starting at where I normally sit (relative to the front wall/back wall) and there were differences. However I moved that chair to the same positions and better bass in each spot (some more than others but all better than the books/couch). 
Anyone else run into this? Bass better when stating vs sitting? I wish I could borrow any pair of stand mount speakers and try this again to see if, what I believe to be poor engineering/stands for aesthetics not performance, is indeed the case. My speakers are on 24” stands but are front ported with a big 4” port at the bottom front raising the drivers up 4”+.

Everybody has this problem, because every room has this problem, because sound waves interact with each other and with the room to reinforce or cancel and this happens in all three dimensions not only the two everyone talks about.

The most efficient/productive approach is to try a lot of different speaker/listener locations. Listen for the best balance of imaging and smooth frequency response. But do not put too much emphasis on really low bass, because this is as you are beginning to realize a problem that cannot be solved. Not with just two speakers, anyway.

So you get the ballpark locations first. Then dial it in with absolute precise symmetry for the best imaging.

Finally, add four subs. These can be just about anything. They can go just about anywhere. The key is four, and in different locations, as the only solution to the room mode problem is lots of different sources.

Do a search for Swarm or distributed bass array.
