Exploded passive radiator & possibly a blown sub?!?!

1 - 18" tc sounds lms ultra 5400 with psi recone.

2 - 18" psi passive radiators.

Alright, so let me start by saying a few months ago I had got into contact with psi about my passive radiators really reaching their limits in terms of excursion.. they confirmed with me that things were alright and.. hey, they recommended 2 18" PR's would be good enough, so obviously I believed them & continued about my business.. 

Last week-ish,  I heard some distortion with the reconed lms and got into contact again.. thinking it was blown and wanting a fix because i had told them it was going to receive 2400w rms.. they assured me it was able to handle the power and told me I was probably clipping and burnt it that way (I just I installed a new alt) and didnt retune the amp. 

Alrigjt, they offered me a discount of the subwoofer recone & i was gonna upgrade to the high exvursion PR's.. we started an order form and all that jazz.. 

Obviously, since I'm buying a new recone.. I might as well turn this one all the way up.. 10sec into the bass drop one of the PR's explode and rip apart.

Now, these are out of warranty.. But shouldn't my email months back count for something?? When I said they were being stressed too much? 

So, I pull the sub, remove the magnet and find something surprising as well.. theres a bubble or void on the coil thats rubbing the motor. The copper wire isnt discolored or burnt. this doesn't look like a blown coil to me. Please correct me if I'm wrong, but this looks like a manufacturer defect that could be covered under warranty(I hopeeeee)

I'm almost positive it hit bottom when the PR blew.. it more or less went free air at full volume when it ripped. Enclosure is tuned to 28, sounds great.. wanted a sql daily. only way I was getting that low and saving space(4.5cu) was with the PR's. As far as getting free stuff or replacements.. Not really looking for that, just a fair shake. I emailed last week offering to ship everything back for a diagnosis and id pay the difference in price for the PR's from their standard to high excursion and id ship these back. I've also never seen a coil with a bubble like that.. was hoping I didn't blow it, obviously would like to save some money if it were covered

Oh .. ive seen a trillion bubbled coils.. lol,  trillions,.. after someone wangs on their shit way to hard., or does a shit recone job, and it tilts into the wall,... just not "factory defect" .  The bubble, in my view, seems to be oddly close to where, its dented eh?  At the bottom ,...  Causing it to arch.

 

And i mean you. The bubble is there, in my guess, because you deformed it, and it arch'd to , well the closest thing.  But im just spit balling.

 

"Obviously, since I'm buying a new recone.. I might as well turn this one all the way up.. 10sec into the bass drop one of the PR's explode and rip apart."

Fair shake,.. im kinda lost on bro, but good luck.  Id like to hear a PR set up for fun. Let us know how it turns out yo...(but i think your fucked)

Thanks for letting me know, I didn't know a woofer would do that. I've just only ever seen unwound/burnt coils before. Probably just gonna send the order through for the recone, hopefully they'll accept an exchange with the $difference for the beefier PR's.. fingers crossed.

Its a neat idea... You save a lot of space by omitting the port, making for a compact 'ported' setup.  I'd like to toy around with one some time.
