Treating a bump around 65 Hz

In an already treated room (so no problems at other frequencies), what's the best (scientifically proven) technology/materials available today to deal with it in your opinion ?
Thank you in advance

Of course I am seated
My question was about which could be the best way to attenuate this problem, now what is causing it, but thank you for your suggestion

Do you see that bump on your mdat as a room mode? (long decay).


Try to move your mic on Length Axial Mode and Height Axial Mode.
It will help you determine where the problem(s) come(s) from.

Yes the bump seems to show a relatively long decay (I am attaching the .mdat files).
Moving the mic on the L and W does not show particular areas where the bump is significantly louder or quieter. Still have to try on the H.
Measurements are made with a calibrated Dayton EMM-6 microphone.
