Can you hear the *individual pitch* of bass notes? That may not be all there is to it, but it certainly is a very important and good way of knowing if your bass vs boom is good.
My suggestion is to play a few recordings with bass, and get very familiar with them. Jazz piano trios are great because there are only 3 instruments, i.e., it's easier to hear or follow the bass. Then make a change to your speaker and/or room set-up. You probably will know quite quickly if there is an improvement. If not, stop and try a different change to your set-up. If things do sound better after the first change, stop and become very familiar with the sound of these recordings again; then you can move on to making another set-up change. Go through this process until you feel satisfied (which may be never : -)
Caveat: the above way of tuning may take you a long time; and a lot of patience that you may not have. It has proven to be the most effective way of guaranteed improvement (without back tracking and getting confused) over time for me, however. One more thing: I suggest you get a notebook and keep track very specifically of the changes you make; and what you hear when you make the changes. BE SURE you keep track (again, VERY specifically) with what your reference set-up is as you go along...small things sometimes make a big difference...just unplugging your video, microwave, etc will result in different sound from your stereo, for example. This will help you document improvement over time, and will allow you to go back to a previous reference to check it again if you wish. Good luck!
