In Reply to: How to lower the resonant frequency of a structure? posted by andyr on May 12, 2022 at 21:39:29:
If you want to lower the resonance frequency of the frame, try adding mass. The higher up you place the mass, the more effect it will have. If you can't shift the resonance such that it's an octave below the x-over, then damp the structure as well.
