Serious Null at 160 hz - Page 2

nosebleedaudio · 6th March 2008

What's between the speakers? Glass/window?
If so that could be your problem.
The room I was referring to problem was the window.
The monitors are BM6 rear port. If I put a piece of 703 in the window the (100 hz) null went away.

Generally speaking, when in doubt you can assume tINY is right.

Peaks and nulls due to reflections and acoustic interference happen in two distinct cases. One is reflections from the source, in this case called SBIR for Speaker / Boundary Interference Response. The other case is similar and is called LBIR, where the "L" stands for Listener. More here:
