Kal,
I'm no expert but a true null is a phase cancellation of the signal. That's where one wavelength in phase cancels another wavelength 180 degrees out of phase. Changing the volume will not eliminate this null. So the way you get rid of it is to change the phase of the original signal and that will move the interference point to somewhere else in the room.
Thanx,
Russ
