Bass traps? (to solve a suck out)


I have a terrible suck out at 61Hz. What should I do to address, I cannot move my subwoofer or room.

one improvement has been achieved as I found one speakers woofers out of phase so it is much better but not as ideal as I hope for. Upon discovering the speaker was internally out of phase now I have a new noticable problem, the bass is behind me and to the sides but at my seat it is way down so again I am lost. I suppose bass traps behind me in corners will tame that but suspect it may further steal bass from my sweetspot.......signed confused and bewildered
Oh, I could have sworn I saw something about a subwoofer in the origional post.

61 Hz has a wavelength about 18.5 ft. 1/4 is about 55 inches. Want to do some measuring of your room and where the speakers are sitting? If the bass drivers are open baffle, the reflections can be either phase.
Yes you did see a sub in original post, I was adding my problems to the thread as I have same issue. Sorry if I hijacked things.
Hi Shadorne, I knew you were not laughing at me,the fact that I was "correct" is pretty funny and probably a first for me on Audiogon.

You said, Since you have bass down to 16 Hz then you can think of the subs role as "fill-in" duty...

What would need filling in? Below 16hz?

Bass traps can help change the way audio waves flow through the room, thus help treat both peaks and nulls, but in my case, after i treated my room with bass traps, the nulls were not measurably better. while this is just my experience, i would imaging that it would be a pretty standard result.
