blown sub?

[Matador 10+ year member]

if u apply some voltage into the coils, and it moves fowards n backwards, does it mean it's not blown? or wat does it actually mean if anythin?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

what would make you think it's blown in the first place.....if it moves freely than no it should be fine...

simple test-------touch a 1.5V battery to it's terminals----------- does the sub move

play a test signal through it --------does it play it clean?

if the sub passes both tests it is most likely fine

i guess by blown i m saying that it used to play fine, but then all of a sudden just stops working. it doesn't play anymore at least in my car. and before they stopped working i didn't hear any pop or anything. i was just playing w a "blown" sub i have and i put a 9v battery actually (instead of 1.5V sorr) and it moves. how can i play a test signal thru it w/o using my HU? like w a cd player or something like that just hooked to the sub or to te amp n the sub.

so if it moves it means it's fine? sorry guys, just trying to absorb ur guys knowledge

9V is ok------- it moved well least we know the coil still conducts electricity and it no so deformed that it's stuck

take it in [your/someones] house and connect it to the stereo---------you need to see if it makes a [buzzing/scratching] sound when playing----------if not turn up the knob-----see if noise appears

if you sub passes this test------i'd say it's not damaged

though some resistance tests would be nice too

You could take the sub and clip the leads and make a passive radiator if it is blown. Would be really kewl to see. What sub is it anyways??

there's no way to fix them if they blown? like if the VCs are blown or something, can i replace them? from where?
