Acoustics


Hej

Anyone who knows how to deal with troublesome bass frequencies? I have two spikes around 45-48Hz and 126-128Hz. Both 6-7 dB with Q-value at 10-15. How do I tame these spikes. Is Helmholtz resonators the way to go, or is it bass traps?

You might consider changing your listening position - too close to a wall for example can really boost the bass. Inches can make a difference. If you haven't already done so, you might check out the Cardas set up - it is at worst a good starting point for system set up.
Hey Simna,

What speakers are you using?

The usual path to do this well is start with bass traps. My current favorites are the GIK Acoustics soffit traps, and then add EQ.

The bass traps help dampen ringing in the room, which makes the EQ a lot more likely to work. Alone the bass traps won't be enough. If you have enough funds, and can do anything in the room, tuned helmholtz resonators would work too.

If you have the ability to bi-amp, or use a sub, that's kind of the best compromise. That way you can add an EQ in series with your bass and leave everything else alone.

Alternatively, Anthem is making VERY nice and affordable pre and integrated with room correction built in. Like I mentioned though, they work best in combination with room treatment.

Best,

@simna, your problem and question is a deep and complicated one. It cannot be answered in a short, concise way here. To get a complete understanding of the issues involved will require many hours of research and reading on the subject of small room acoustics.
