RIP 15" btl

[IgnoreMe 5,000+ posts]

so my btl stopped working today when i was listening to it on volume 35/70 on the highway. i thought maybe my wires came loose. get home, pull out the woofer and this is what i see

at first glance i thought i clipped it. i take a look at the coil...its fine. never smelled anything either and everything is in the same condition as when i recieved the sub. and the other tinsels dont look burned to me at all. i am the third owner of the sub. it does look a bit burned but the coil looks perfect so who knows.

upon closer inspection it looks like that single tinsel was a good bit shorter than the other 3 which seem to have enough play to move freely. this leads me to believe that the tinsel slap issue i thought i was having was that tinsel being tugged on.

the sub does not bottom out in the enclosure, and i have my subsonic filter set. it was in a box that was roughly 4.3 or so cubes at 31-32 hz (after recalculating and seeing an error i made in the original calculation. and was being run off a kx2500 pretty conservativly.

well, ill talk to FI and see if there is a way to fix this issue without having to do a complete recone. RIP BTL, after like only 1 week of owning the sub //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

same thing happened to my BTL. Coil looks brand new, no smell ever, but the tinsel popped. All you need is some new tinsel wire and you're good to go.

i have seen 3 or 4 others with the same issue.

the sub didnt even bottom out so it wasnt over excursion, i just think it was too short of a tinsel i would bet. definatly looks burnt in my opinion, but i never clipped it especialy with somewhat conservitive gain settings.

the ones that popped on mines were the ones that were slamming against the spider btw.

so its chill to just solder a new piece in there?

solder ends up being kinda hard once its in the wire, did this cause any exagerated tinsel slap with the solder hitting the pad and spiders, versus a regular unadulterated soft tinsel wire?

well im the third owner, and ive barley had the sub but all 4 tinsels have left marks in the spides and felt pads.

what you need to do is cut the wire off very close to the cone. So that it doesn't affect the tinsels flexibility. I'll link you to the thread where it shows you how to do it. 1 sec

Those look burnt? Or am i blind... Upgrade tinsels ftw?

like i said, they definatly look burnt a bit. however they seemed fine when i recieved the sub. same basic condition as when i got the sub. i know i didnt clip the sub. the coil is fine and the rest of the tinsels look fine too. but for some reason that one looks burnt. the camera definatly makes them look a different color than they are.

by the way, there is no upgraded tinsels for btl's. the tinsels that come stock with the sub are the upgraded tinsels.

apocolyseboy: thanks man i appreciate it.

I had this happen on a Type-E long ago. I looked at it, and it seemed shorter and had a black tint/burn on the end of it. Turns out, the tinsel had popped on the previous owner. He clipped the end of the tinsel off and soldered it back on himself and the black tint/burn marks on the tinsel were from the solder iron. Maybe this is your case as well?

I still dont understand why RE always insisted on running their leads this way and now Scott just does the same with FI..

Makes more sense to me to "direct connect terminate" them like DD, Audioque do or to weave them like so many others do.

Then you are not familiar with the other school of thought on the subject. Imagine what that spider does... it flexes. Now imagine weaving a wire into this apparatus, that you want to flex... to flex linear and predicatably. Im sure you can see the complications this adds.
