low-impact soltions to a very bad room.

Room Acoustics Forum by Rives Audio

Welcome! Need support, you got it. Or share you ideas and experiences.

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.
