| Re: method to identify room modes
I don't see the images you posted.
It's important to remember that you may have to move your subs from the corners if you want to get the best frequency response. Corners increase bass but may nor fit your room/setup.
Did you try to change the phase on your subs in order to correct the NULL areas ?
Also, you should only be interested in measuring around your sweet spot. Will you seat in the north east corner ?
Another trick may be to test with open/closed doors. You may be surprised to see how much difference a door can make ......
