Phoenix Gold Phorum

i just got a sub on trade and didn't try it. I got it last night just put the sub box in my car and can to work today. i tried to move the sub up and down to see if i could hear the voice coil rubbing. to my suprise the sub is suck in the down position and its almost like it was glued in this place i can't get it to move at all. I was told it was working but look like i got burnt . I went to my car to try it to see if some power will move it but the sub is 100% dead it doesn't move no sound almost like i have not conected the sub to power
its a focal 10" in a prefab box but what are your thoughs.
It doesn't smell burnt and look new?

Is it a DVC? Is one of the coils wired backwards?

sorry tom single vc
the sub doesn't make any sound it like it is glued in the down postion
I try with my fingers to move it back up but im afaid to damage it more
maybe 4 hands can add the presure to make it move back up but it is very very stuck right now?

If it sucks in that almost sounds like your amp is broken...

Does it come back out when you turn the amp off or is the sub stuck in the down position always? If it's stuck, it sounds like it's totally blown...

the amp is 100% fine it the sub
I took the sub out of the box so its sitting on the counter. it will not move up and down at all. the amp works great on my jl 12w6v2 never had a problem. I know what your saying but it will not move at all with out power just sitting there its almost like its glued in the down position. even when i apply presure i can't get it to move up or down. its about as soild as a peice of wood zero movement what so ever
I think i seen something like this on you tube were a guy fried the sub by plugging it intot the wall and the voice coil welded its self to the magnet

sounds like the coil might have got hot and expanded a little?

Sounds like a "dropped coil". This is where the coil get so hot the glue holding it in a coil shape fails and the coil unravels then binds up the speaker.

If it does not smell at all, and is indeed a dropped coil, I would stay well away from that model of speaker in the future. No good speaker would ever drop the coil without a smell remaining. It is a sign of very cheap glue being used.

sounds like its fucked.. Im a little mad

What would cause a sub to stop moving...............plug it into a wall socket..... It'll stop real qwik like...... And fill yer house with magic smoke smell.....

That happened to me once, got me mad as hell too! Sorry to hear that...

Some subs do ok on 120v ac. I suspect the free air application helps with cooling.

Did you buy it from someone on the phorum?

you may could find a speaker repair shop in your area that can fix that sub maybe ever put a voice coil in thats more geared to your setup.

I have seen it happen to a buddy's sub(rf funny enough eric) after he took it out of his car and left it in his garage overnight. I think the change in temp hurt it as it was cold as hell that winter. He did end up having it repaired though, not sure if you can do that
