Guys, I have 8 traps in my small rectangular room. Some up to 8 inches thick behind the speakers. Still, I have peak from 50 to 100 Hz. And the area from 100 hz to 500hz is showing big nulls . Not having room for more traps, what other options are available to treat these areas? thank you.

More traps. :mrgreen:
Yes, Ok Ethan, did you miss the bit about not being able to fit more traps ? :D :D Ok, after staring at my traps for half an hour, I think I can do this. How would the following effect say 60hz to 400 Hz... My traps in the front corners and behind my monitors are about 6 inched thick. Now if I added 4 inches more of 703 to EACH one of the four traps, could I expect any significant improvement in these range of the spectrum? I ask, because if not, I just as soon as probably leave it for now, given the whole lot of mucking around involved. It seems about my only option. I have a really large null, at most around 16 db at 200hz. But its bad from about 60hz on till 400 or so. This is despite my thick traps on all 4 corners, RFZ, etx. A might disappointing. On the upside 400hz or so to 3K is around only 3 db or so either way.
This is despite my thick traps on all 4 corners,
What about the other 8 corners? A room has 12 corners, not 4!!!

That will help the lowest frequencies a little, maybe even more than a little, but trapping wall-ceiling corners and even wall-floor corners will help much more. --Ethan
