Yeah, yeah, give us cabinet vibration tests old man.Here is what I mean about this stuff taking a long time and it being damn near impossible to do these lengthy tests
Joking of course. But can that data be extrapolated from any currently done measurement (extreme would result in visible resonances)? Because if the speaker isn’t well damped and the cabinet vibrates like heck during bass notes, that is of course not ideal. Wouldn’t cabinet vibrations mean a loss in acoustic transfer and thus SPL is lower?
If not, a “I put my hand around the cabinet while playing bass and it felt inert” would work if you can fit that in during your subjective listening; if not, of course that’s totally fine.
Also, circling back to your video with the guy from Klippel when you talked about phase: I was wondering why impedance/phase plots show resonances, and while I’m not too sure on impedance, one explanation I found online is that phase is related to the derivative of the FR, and thus when the FR suddenly spikes the phase will too (and also that group delay is a derivative of phase shifts that aren’t minimum phase).
