just found out from testing that at about 110Hz is where it switch to use of the bottom woofer mostly, im literrally sitting right next to them so my ears are off axis =P, and without my room resonating (it does at about 80-100Hz, another problem to tackle) it almost seem the bass was gone completely. maybe i should move them further than 3 feet from me lol.
edit: didn't see your reply tiamat, i am going to do some google a bit to understand what you just said. right now they are placed about half feet from the front wall (the wall that is facing me)
Basically, what I saying is that it is a possibility that the sound that exits the rear of the speaker hits the wall behind them and reflects back into the source wave cancelling a portion of it.
Easiest test: move speakers out more into the room, retest, see what happens to the null. If it goes to a lower frequency, this is the problem I talked about.
When you say they are 0.5' away from front wall, are you talking about the rear of the bass speaker, or the front of the speaker cabinet? Measure (with a tape measure) the distance from the very front of the speaker to the wall behind it, that will approximate the null 1/4 wave frequency.
Speed = distance * frequency.
Speed = 1139 ft/s
distance = distance from front of speaker to wall behind the speaker
This is only 1 of many possible problems you could be having, but it is an easier one to figure out. Another possible problem is that your listening chair happens to be in a bad spot within the room. This is another one that is easy for you to figure out (just move your chair and remeasure).
