GAHH! Help with my room...

I finally got REW (room eq wizard) working and did an analysis of my home studio room. I have bass traps floor-ceiling in all 4 corners and 2 5x4' panels on each long end wall and wall/ceiling traps above those and a 5x4' cloud above the mixing desk. Floor is carpet. I used another eq tool and it reported a big null at about 90hz. REW confirms this. Is it the room or my speakers or mic??? What can I do about a null like this, it's a critical bass frequency? Would a sub help? Room is 16'Lx9'Wx8'high. No real high absorption at 1 reflections though the ceiling cloud has helped noticeably with that, along with imaging.

Most rooms have 12 corners. heh

Nulls are always the room.

More bass traps. After all the corners are filled with traps, next is the front and rear walls surfaces.

Not as much as more bass traps.

Haha, I guess that's right, I wasn't thinking in 3D. heh
Here's a question for you Ethan, I've been all over your site and I'm sure ALL the acoustic forums...
There's not a lot of room for much more treatment in here. I could stuff the space behind the 4 corner traps with more rockwool I guess...

I've found that between the current listening position and 2 other positions, the last being standing up 3 feet back of listening, I can get a composite "accurate" graph if overlayed with each other, that is, there's a good even response over the 3 positions as opposed to just one. One position is ideal but I may not get that in here so would it be better than nothing to try and judge a mix based on 3 positions other than 1?

It's never a bad idea to walk around a little. If nothing else, it sort of simulates what others will hear in other rooms.
