I can not tell from the latest picture, it is too blurry to make out. Are the holes visible threaded or not?

Ask your doctor if DIY is right for you. Side effects of DIY may include anxiety, elevated blood pressure, lightheadedness, rapid heartbeat, skeletal muscle flaccidity, euphoria, psychological dependence, insomnia, confusion, blurred vision, implusivity, uncontrolled or repeated movements.

The bolts are too short, not too long. They're meant to thread into the motor.

Looks like neither of the bolts got threaded into the motor with one being comically short.

And the top plate of the motor is still on the basket, at least half of it.

Right, they didn't thread into the rest of it, though they should have.

Could probably scrape off the adhesive and save the sub with some fresh adhesive and/or tacks, but who knows how long it'd last for.

It is not clear from the picture of the top of the detached motor if the holes are threaded. They would have had to be threaded at the same time in order for the bolts to pass through both pieces that are threaded.

Looked threaded, but you're correct. It may or may not be aligned. I'd imagine it should be.

That said, the different length bolts are a bit odd.

Are there pieces of the threaded screws still remaining in the bottom plate? I can't imagine that the screws sheared off.

So if WAF wont allow for subs in the living room, but you have a basement packed with subs why not put a TV down there?

I think putting a tv down there would cut into the space for his TBGS (that's tactile below-grade subs for those who don't know).

Agreed. After @michael hurd wrote some of his posts, I realized my original assesment was wrong.

Sorry about that. They are threaded. Yes, it looks like the fasteners are too short.

Not a bad idea. But two reasons why not.
1.Stereo receiver and all the other speakers are upstairs.
2.Basement is unfinished and there is not furniture to speak of.

Final Update (I hope!!!)

Props to Scott, Brian, and Ficar Audio in general! Replacement speaker arrived today as promised (with a pre-printed shipping label to send the old one back.) Installed and tested with ALL my bass woofer test tracks. Had a couple tracks clipping the inuke 6k into the red. But speakers survived. Movies should be no problem. The original UM18s survived multiple movies but bass tracks killed 'em pretty quick. Remember, this was after running a dedicated 20 amp circuit and bass torture test trecks (like Bass I Love You, DJ Magic Mike, etc.) The subs got hot, and they have the electronic smell that electronics like amps get when hot so playing for long extended time with these tracks is not smart. But they survived all my test tracks. (Hear that @BassThatHertz ? I need some more tracks to test!)

Lessons? I don't know. Maybe that an inuke 6k kills subs rated for 1000 watts when a 20amp circuit is supplied to the amp, but a sub rated 1750 watts is OK, even when pushed. A Mach 5 Audio FTW-21 rated at 1200 watts RMS will probably not survive either. Two had the leads seperate from the coil when connected to my inuke 3k bridged. (The 6k is two bridged 3k's from what I understand.) When up close to the Ficar's in the ported cabs, my eyeballs even felt a little like @eng-399 's GTG when he cranked up the John Wick 2 underground scene. I was feeling as much as seeing. Hopefully these subs last a while.

I,ve had 2 UM18 connected to an 6000dsp without any issues. Clipping an amp is never healthy for the amp or the subs.

I did not have any issues until I played the bass tracks that torture subs. Music an movies were OK at first and I never tripped my 15amp breaker, either. Once I tried to play the bass torture test tracks, I was tripping my breaker in a couple seconds. I ran a dedicated 20 amp breaker. Then, I stopped tripping breakers but started frying subs.

clipping is bad no matter how you slice it. If proper limiters were set, I seriously doubt you would have burned those UM18s

Quite possibly. I did NOT have a mini DSP at the time and did not set the amp limiters. But, sealed so figured it was OK. With the Ficar SSD neo subs, I have three 6 inch vents. So I now use a mini DSP, set from modeling to limit xmax at lower frequencies. MiniDSP set as high pass 4th order Butterworth at 22Hz now.

Movies and music were fine with the UM 18s. It is the woofer torture tests that initially tripped the breaker. With a dedicated circuit that did not trip, the UM 18 subs burned up. With the replacement Ficars all is good (so far).

A clipped signal will eventually burn up a 24. Just saying.
