low-impact soltions to a very bad room.

I'm new to this branch of the asylum, and I'm hoping I can find some helpful advice. My searches here have been informative but I'm uncertain as to what applies to my situation:

*14x14x8' room
*Speakers centered on wall, 4' apart, 16" from rear wall
*Wood cabinet between speakers, 4" clearance sideways, front of speakers in line with front of cabinet
*Listening position is centered on opposite wall (couch)
*Various doorways, doorless doorways, furniture, and windows.
*Speakers: JM Labs 706s

Problem: I'm drowning in bass. Back wall resonates at 130hz, floor resonates at 120 (at least this is what I hear when I play computer generated test tones, I haven't had the chance to measure SPL). I mean the floor and wall actually vibrate and produce noise. Standing waves at 70 and 80 amplify those frequencies at the listening position, and when I move around the room with pure tones (70-130) playing I hear massive peaks and valleys depending on location. Holistically, from the listening position, bass and mid-bass sounds about 20-40% louder than the rest of the music. I'm happy with accuracy and soundstage, I feel like turning down the volume on frequencies below 130 would give me a natural band, but I may well be wrong.

Constraints:
We rent, and this is primarily a living space. Moving the speakers, cabinet, or listening position would be very difficult. Tube traps/panels would be very undesirable, and cost must be minimal. I know this doesn't leave much, and that's why I'm posting here.

I've considered:
*Speakers that produce less bass (Quad 11L instead of 12L, Dynaudio 42 instead of 52, etc...)
*Equalizer (I'm not certain whether turning down the low end could give me a natural curve or not, and I'd be shopping on a tight budget)
*Room alterations (must be cheap, non invasive, and low-impact)
*Speaker/Position movement (Not much is possible)

Help! Thanks.
