[QUOTE="Vladimir Kuzmin Sr., post: 215682, member: 15095"] I hope you've read the article here [URL]https://soundforums.net/articles/loudspeakers/damping-factor-soggy-at-best-190493/[/URL] where stated that "Scientifically speaking, Damping Factor is the ratio of the resistance component of the loudspeaker’s impedence to the resistance component of the amplifier’s output impedence.

I can add that this back-EMF is really big in LF drivers with their heavy voice coils and diffusors and they "flop around" just at their resonance frequency (when DF is extremely low). [/QUOTE]
