I would like to destroy a subwoofer. 400 watt rms, 3 inch dual 2 ohm voice coil. I need to keep the woofer intact with no visible damage. I just want to destroy one or more of the voice coils. My plan is to connect the voice coil (s) to 110 volt ac. Easy. Just listen to the 60 hz tone until it fails. My other option is to connect the coils up to a 12 voit deep cycle battery with 800 CCA's. What do you think?
Get youself an arc welder and connect the ground to the negitive and the stick clamp to the positive.
WHAT FUN!!!!!

DC wouldn't be as likely to cause damage to the spider.
People do this to try to get woofers exchanged under warranty but many manufacturers won't warranty woofers with open coils.

I didn' note that yours was 2 ohm...
Better send me the driver and I will destroy it for you
(Ganted... 😀 )
tape a couple of heavy lead fishing weights underneath the cone, to one side and play a low tone... the weights should cause the coil to rub on one side and eventually fail....do it out of the box.
The jerk rep will not take back a sub if it is not 150% bad. I returned 2 dual voice coil subs to my supplier that were smoked. Voice coils did not check ok. But they did not read 2 ohms. Voice coils did not rub, movement smooth. Sound was weak. Subs smelled so bad they left an odor in my vehicle. New subs were connected to a customer's bad RF 1500 watt BD amp. I just want to make sure they do not work 151%. I would rather not mention the brand name. It might get back to my supplier.
Hi
Best way? Nuclear bomb, you won't even have to clean after it + there will be a lot to see
But in any case I would do that, not intentionally

why...put it between phases, 400v where phase is 230v, you will get a bit more, and blow more things up

If you want to go that way we can still go better as our phase to phase is 415v which is 86112w.......
Fraud is a criminal offense in most countries. Oh, and what makes you think they won't check? Every damaged driver that I see gets taken apart either for QA purposes, sheer curiosity, or both.
do they perform as advertised and/or specified?
That becomes your complaint.
Work within that.
Have you tried measuring the T/S parameters?

Andrew, you must be confused, this is the car audio forum.
In car audio you just put the driver in a randomly sized box and run kW of P.M.P.O. with heavy clipping through it until it dies an undignified death. Then you return it under warranty and try again.

ROFL!!!
Reminds me of the first shop manager I had to work under.
A kid comes in and wants to put 4 8" woofers into his compact station wagon. I help him choose 8" Pyle Drivers based on his budget. I designed the box based on T/S parameters and start cutting the wood...
'Redneck of the Century' says "That box ain't big enough for 4 8's." (I can talk bad about Rednecks because I'm one, too. See my profile if you don't believe me.)
Me: "Actually it's exactly what they need. I calculated the size based on the speaker's T/S parameters, and they tell you what that particular speaker needs."
Him: "NO. That box is too small. You need a DEEP box for DEEP bass."
How silly of me.
So, I walked away and hand the job over to Mr. Brilliance who built the box 3 times as large as needed.
When done, he fires it up and the Pyles sound like garbage. He replaces them with M&M's at about twice the price, which coincidentally need a larger box and they sound much better.
Him: "See, I keep telling ya'll those Pyles ain't worth nuthin. I don't know why you keep sellin' 'em."
So that day I learned that you need a deep box for deep bass and M&M's were better than Pyles. And here I was taking physics classes to learn about this stuff.
Which inspired me to coin the phrase "Redneck Logic" for his thought process.

Now why would you want to do something properly. Just guess and if it doesn't work the way it should blame the equipment....
