Bass traps? (to solve a suck out)

When I move the SPL around even a foot or two it changes everything but the suck out cant be cured to any huge degree so I am curious as to possible solutions

This kind of result is quite normal - you may not even realize that you were getting "one note bass" for years. If you get it right then the bass riffs anchoring much music will take on a whole new world - a balanced sound where each note is audible. The problem is your room.

finding out the Emperor has no clothes isnt fun but is needed to get to the performance we all strive for.

Yes and perhaps it would change some peoples attitude towards the gear merry-go-round if they realized what a major effect the room plays.

The only real solution is to have way too much bass..so add another sub....then you can cut the peaks down to get a flatter response. Going from -15 db trough to -6 db will make all the difference...don't try to get flat and avoid boosting unless you have extremely powerful amps and huge woofers....most systems would distort terribly at modest levels with a 15 db boost in the hard to drive bass.

Bass traps help suckouts but you need a lot of big traps to have significant impact - nevertheless every trap will help provided it is large and at least 4 inches thick and placed in a corner.

No one note bass at one point I am down about 13db so its there just not flat but not ideal for sure, and I never said to myself it doesnt sound right but the seating and speaker positiion are both new so maybe I could trim that a bit but I know not completely. With one note bass wouldnt that would be more of an issue with peaks masking things right? I know its my room but have only been here in new house for a few months so I knew before I even did the test that it was highly impossible that things would be perfect, its a double edged sword to know of the issues, one hand being it ofcourse it stinks to see you have more work to do then you planned but its great to atleast know the issue and have the ability to try to change things. Tomorrow I am going to get back to measuring and will have help to move things around so I hope to trim that enough that I can insert Behringer into my bass amp and electronically raise the dip. Having a bi-amp system is perfect for this.

bass traps cannot fix a suck out, but you should still treat your room to achieve other benefits.

you can equalize a bit by overlapping your main speakers with a subwoofer, then adjust the phase control and sub level until you reach a desired result. you may not be able to completely solve the issue, but this has worked for me in the past. also, you can try active room correction too.

Hi Holeneck, you said "bass traps cannot fix a suck out, but you should still treat your room to achieve other benefits."

That is a completly false statement. Bass traps do indeed flatten peaks and raise nulls IE: fix suck outs. They also narrow the width of the peaks and nulls among other benefits.

Bass traps cannot fill in bass nulls.
