Ouch, you are confusing speaker damping with amplifier damping. What you have stated is all related to the Q of the speaker. what i am talking about is damping factor (called damping in short) of amps.
Simply put damping factor tells you how good an amplifier is at controlling a speaker system, in electrical terms it is the ratio between the nominal load impedance (8 ohms for home audio, 4 ohms for car audio) and the source impedance of the amplifier.
Amplifiers with higher damping factor can provide varying amounts of current without changing the applied voltage to the speaker system hence with the better ther amp the more accurately the speaker will reproduce what the amplifier is trying to tell it to do.
