Terrible bass boost @ 130hz

Hello! My room is oddly shaped. I live in a studio apartment, so I have to make room for sound equipment alongside my bed, dining table and the rest. This, when coupled with the odd shape, leaves me in a doozy of a situation acoustically.

It seems regardless of where I place my speakers I get a gross bass boost right at 130-135hz. This makes mixing inaccurate and listening to music often annoying (sounds like some idiot with a poorly-tuned car subwoofer at a traffic light) Recording isn't as important for me since I do most of it somewhere else, but I like to mix here and so I'd like to fix this.

Problem #1: I rent, so I can't stick anything on the walls.
Problem #2: This frequency is low, and thus I'll need something hefty.
Problem #3: Space is limited.

Here is a rough outline of the corner where my computer and listening station are located:

The lines with circles are my speakers, with my monitor (flatscreen) in between. The bigger corner is about 2 feet wide and the smaller one about 10 inches. I don't have measuring tape anywhere handy, sorry!

Three out of 4 corners in the room have this similar shape, making for a total of 7 corners in the room. I notice a complete lack of bass when I walk into the flat corner (diagonally across from where my computer is).

: This is what it sounds like in front of my speakers. I put my ECM8000 about three feet in the center of my speakers and ran a sweep from 110 to 220hz and a slow sweep from 120 to 140hz. The problem should be very obvious in the slow sweep!

Any ideas for solutions? Any help at all is greatly appreciated! Thank you!
 
First things first - relocate away from the corner spaces and get those monitors away from the walls........ that should help bring down the bass boost quite a bit. (Locating speakers near a wall can boost bass response 6dB or more -- putting them in corners can boost it 12dB. That may be your whole problem right there!)
