why exactly does impedance change?

[QUOTE="IgnoreMe, post: 3510322, member: 551352"] shit, i should of mentioned, im talking about like when im pushing on the cone by hand [IMG]//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif[/IMG] . like say the sub is not hooked up to any power so there is no current going through the coil. for example, when im hooked up to the sub with the dmm, it says 2 ohms. when i push on the cone the value changes. no power is running throught he coil. im just simply putting it from point a to point b and holding it there. i was trying to take out amplifier power, and an actual freq, as variables that would change the reading. im having a hard time grasping why the resistance reading changes with no power hooked up. ive always accepted it and thought nothing of it, but now yeas later, i am wondering why.
