I would think you would need to put at least a few watts into the speaker to even begin to get reflected stuff inside the cab with enough energy by the time it got back to affect the speaker's movement and create resonances and dips in the curve, but I haven't measured one, so take however big a grain of salt you need with my supposition....Will driving the speaker cabinet from the headphone output really work for this? We are trying to measure resonance in the cab, I would guess that the acoustic energy from the headphone out will be insufficient to excite any resonance? Are these resonances even linear in nature, or do they depend in loudness? @FractalAudio, any thoughts on that?
