View down the vent pole on my sister's Audiobahn. Sub works fine, but is this normal??

View down vent pole of my sister's Audiobahn...sub works fine, but is this normal?

sure doesnt look like it! is it a dvc? all i can think is thats bits of 1 vc and the other still is working fine.

or its just stray wire that fell down there and is attracted to the magnet

It is a dvc...I'll bet yer right about it being loose conductor (prolly from the install) that the magnet collected. Lol, now I can get some sleep!!

the vc is unwinding,,,,def not a good thing..

most definately voicecoil, pretty soon it will have lost enough coil off the former that it will impede movement of the sub, have seen it on one customers sub.

It looks like one continuous wire, so I would probably assume VC as well. Prognosis is not looking good!

Well damn it then it's a good thing she's not using these one right now (she using 2 RSD's I sold her)...it think she was planning on puttin it in her hubby's car. I'll hafta let her know she's gotta do some shopping then

I have personally never seen an exploded voice coil (speaker), but how would it unwind and come out if it is between the magnet/pole and spider? I have seen a sub about 12 or so inches deep with dual spiders and a partially exposed voice coil, but am VERY interested to see how extensive the damage is to this speaker. If the magnet or pole piece had fallen apart, then that would be a no-brainer. I believe the OP said it works fine...

Can we have some pics of the damage please? Thanks...

the one I pulled apart to investigate it just appeared the voice coil slipped off the bottom of the former, it only takes a small bit to catch and as the speaker is run it will just continue to pull more and more coil off the former until it leaves no gap between the motor and the voice coil

Yeah when I pulled it out of her car a while back, it was working fine (other sub wasn't working though). No other visible damage. I'll get it from her later and you guys tell me what pics of other parts of the sub you wanna see.

Take note, the view you are looking at would be the inside of the former but vc's are wound on the outsides of the former. If it was the/a vc then you would definitely have/hear a scratching noise.

good to know...I'll get it hooked up soon to confirm it's current playing condition.

might be able to get it out with some compressed air and vacuum, or a magnet but not sure if I would try or not.

If its the voicecoil, its fucked anyways. If not, it could damage the sub. I think removing it would be pertinent, as long as you could do so without damaging the woofer otherwise (unless it's already fucked, then who cares?)

yea its a damned if you, damned if you don't as it will end up in a place it shouldn't be sooner then later. Try one of those magnetic screw catcher tools and see how much you can get out before moving to the vacuum.

good ideas guy...i will definately try tot get that out there before running the sub again.

Some of you fellas wanted me to follow up on this sitiuation...so I ripped the thing apart for ya here's what she looked like in there!

Damn!

Hooooooooooly

yeah, quite a bit of that coil had unwound and it looked pretty burnt...Hell, it was still workin, though! well, until I did this to it

ok, well now we can answer your original question of what are you looking at? a POS........

lol, not an audiobahn fan huh

are you after lookin at that? Never seen a sub do that before.

LOL, well the cone didnt do that on it's own..I did that while making my way through the dustcap and spider to check out the extent of the damage to the VC. That speaker actually sounded pretty good for me for a couple of years before I gave it to my sister. I know she ran them to clipping most of the time and wouldn't listen to reason, so I'm not surprised that the VC gave out.
