Bass traps? (to solve a suck out)

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.

Hi Onhwy61, if this is so, do tell me what works.

A bass trap is a passive device that can only dissipate acoustic energy from a room. As such it can never eliminate a null in room response since it cannot add energy into the room. However, if you have two bass peaks it's possible that room traps can eliminate the peaks to generate smooth bass response. But in that case you didn't really have a bass null, but two bass peaks.

If you measure room response in narrow enough bands you'll typically find any number of very deep and very narrow nulls. As a practical matter they cannot be eliminated. Fortunately, they usually aren't a noticeable problem. Broad band nulls are a major problem. Repositioning the speaker and/or listener is the best way to address that type of problem.
