i wanna see pix of the sub parts before i pass judgement.
Fi's fail most the time for ripped spiders or the leads damaged from being between the spiders.

I'm right. I'm always right. Even when I'm wrong, I'm right.
pics are on a thumbdrive at work. i will post them once i get them off the drive.
Fi and I went back and forth. They agreed to pay for the recone if I pay for shipping back to myself. I agreed. Out $120 but better than nothing.
To explain why the coils measure 1 ohm and 2 ohm:
I am satisfied with the offer.Yes, the coil is a quad 2 layer with pairs of coils wound in parallel. This boils down to 4 1.4 DCR coils with pairs wired in parallel at the coil winders to yield the proper packing factor for our needs and a dual .7 Ohm (1 Ohm nominal coil). One of the coils came apart when it unwound and broke. This opened up half of the coil. Each is tested before leaving to ensure proper function of the speaker as well as DCR.
If the coil left here with a 1.4 and .7 coil, there still is no way of wiring it that would draw more power or be more harmful to the coil than a correct D.7. I have seen the swelling and coil delamination before and can reproduce it. It stems from a coil that is wired out of phase and provides little to no movement and all heat build up.
The terminals are placed correctly (with respect to color and phase) and it is impossible to wind the coil out of phase at the factory. Leads were not crossed under the cap (which would be very difficult for a builder to do).
We can not find any specific inherent factory problem with the build of the sub that would allow this to occur.
I will recone the sub free of charge if you agree to pay for the return shipping.
To the following, i replied explaining that the sub only saw music for 30-40 minutes and 30 second sweeps of sine waves. I don't expect an hour of use to cause the sub to look completely different:
It hasn't been addressed how "out of phase" coils could still have significant output, because it wouldn't. In the end, they blame me but agree to fix the sub. I know the coils were in phase, but settling for paying shipping both ways.The tech log book on your speaker indicated that the suspension and spiders were as stiff as a new speaker and if it did move it was very little. The log book also states that the coils were wired out of phase of each other which swelled the wire off of the former causing the coil to unwind and fall off in the gap. If it were wired properly the suspension would have shown wear and it would be broken in some as well as the tinsels would have been moved a bit from their factory location, but according to the notes is very close to the same suspension compliance as a brand new sub and the tinsel leads show no signs of any significant movement.
We are on week 4.

So they are saying the coils where out of phase but still making you come out of pocket after waiting 4 weeks? You're going to be pretty loud where the coils are in phase. That's good news

I still don't understand if they are saying it was fualty from the start why would you have to come out of pocket for anything? In phase or not they said it was out. That's a defective coil is it not? That's a manufacturer defect. That's a full warranty.

No, what they are doing is avoiding any blame. They're saying HE wired it out of phase. However, as anyone that's done this will know, wiring a sub out of phase produces little to no output. However, Richard experienced impressive output for the short while it lasted, which proves right off the bat that it was not wired out of phase. I don't know why it is SO hard for Fi to imagine that of ALLLLL the subwoofers they put out, just one might have had a defective coil? That doesn't mean Fi did anything wrong, maybe it was bad coming straight from Precision.

I am taking what I can get. I feel it should be a full warranty claim but they won't. I either throw away $460 or spend another $60 and have something to show for it.
In the future I will not buy subs from online retailers. My local shop would have exchanged over the counter.

A local shop wouldnt do it for everybody though, at least the ones I know of. If they know you and you've spent money with them they tend to not give a hard time. So many shops take advantage of people though. I got tired of sending ups across the US I'll stick with my shop but I do know the owner and he does take care of me. not everybody has that.

looks like they went back to floating leads too many failures with the leads woven in the spiders.
dont think that bout all online places i take care of my customers even if i gotta reach in my own pocket and call it a loss.
if the coil isnt burnt it should be under warrenty...
online dealers need to realize they will live and die by word of mouth and they have now lost keep_hope_alive as a customer over such a small issue, and many others reading this will also think twice before ordering anything from fi, i personally never bought anything from them only because i seen way to many post on how hard it was to get in contact with them and now i see how they deal with customers with problems
There is absolutely no way in hell they're reconeing a speaker for 10$ If you know a way to do that you will get rich quickly selling recones for 50$ and undercutting everyone else by half.
If you buy 100 coils the price of a 4 layer 3" is close to 30$ , I can't imagine them dropping down to 10$ even if you bought 10,000 at a whack. Really I doubt you could get garbage quality Chinese coils for 10$
I have twice (and I break a lot of woofers), both 18" woofers, 5KW and up pushing hard, and they stunk bad before they let go.
If this is manufacturer defect it is in the coil and nothing Fi did or did not do. Anything over 1200W continuous power will make a 3" 4 layer coil fail, Once you cross that threshold of where it can't dissipate heat fast enough they will overheat and fail quickly, exponentially faster as you increase power or decrease cone movement (cooling)
Calling bullshit on this without some sort of proof.
I've only ever had coils go slinky from gross abuse. I've had some subs break within a short time after building them, but that's mechanical from either me being abusive or trying to skimp on glue. Of course you would know if it was a glue issue.
My thoughts exactly, and a worthy topic. One of the reasons I don't like 18" woofers, really. Side by side a smaller cone will move more and cool better. I find smaller drivers hold thermal power noticeably better than larger (assuming same motor, coils, and suspension).
Coil does not need to look black to have failed from heat, though almost always you'll get some smell before they fail from over-heating. Consider smaller drivers move more on the same power and cool better.
This is the most accurate explanation of cost of coils and most likely explanation for cause of failure. I wouldn't rule out that Precision made a dud coil, but this seems most likely.

I guess Jacob doesn't buy enough of them to know what the real price is right? Please tell me how I can get my coils for 3-4$.
