Interesting (or not) dilemma


I could use some advice here.
I have owned and enjoyed a pair of Revel M20's for a decade. Still like them 
with one important exception.
Due to logistics, I have them on stands some three feet from the back wall
with my seating position seven feet from the speakers --as far back as possible--there's a wall behind the chair.

The room is far from optimum-no carpeting and bare (ok some paintings) walls very solid parquet floors.
(I have a wife enraptured by minimalist design! Room treatments are out.

The problem. These speakers have a serious (on some recordings) bass "hump" at around 100HZ (my guess based upon a comment in Stereophile's original review--it IS there.). It is a distinct boominess
at a very specific HZ level and not present above and below it. These are rear ported speakers with otherwise wonderful sound.

As a solution I was thinking of adding a small subwoofer (REL7) and utilizing a cross over point to
take some of the bass load away from the Revels. Am I nuts? I could use some intelligent advice.

Thanks

Is carpeting out of the picture? It could help in a lot of areas of the sound. Or at least a large area rug?
Assuming you can't get rid of your wife anytime soon for whatever reason, the best solution may be some form of room EQ.  Something like the DSpeaker anti-mode 2.0 would take care of the hump and probably some other issues, and I've seen them pop up used from time to time for 500-600 bucks.

I doubt a sub will help since you'll likely want to cross it over well below 100Hz, although a sub is still a good idea for the other significant benefits it can bring.  The anti-mode 2.0 can help integrate that as well.  Best of luck with this.

Enter dimensions in mm to find the likely frequencies of your peaks and nulls - experiment with placement accordingly. 


+1 nrenter,
I also had a problem with over ripe bass, eventually solved my issue by plugging speakers ports. It did require other adjustments, changed speaker cables and power cord to integrated amp, but after some time adjusting to new sound, much improved.
Good luck,Gary
