10dB resonant peak at 40Hz


Hi all, room is 13' x 15' and am getting a 10dB room resonance at 40Hz

How to eliminate? Can't move the speakers and room treatment would need to be minimally invasive.

Second, I have not had good success with DSP as it changes the FR but also degrades the sound quality.  Third reducing sound at 40Hz does not address the problem. Sure the hump is gone but I think I would loose bass quality as what is left is still a resonance and not music.

What did you use for DSP?

Your concern about hearing resonance rather than music can be addressed by a combination of HP filter and sub. By reducing the energy below 60hz in your mains and REPLACING it with a sub with DSP that you can move around, you would have some control over the low end. The SVS subs have great DSP software that can tailor the FR precisely in the low end without affecting the overall SQ of your mains.
