JackHammer is the most enormous, mind-blowing subwoofer ever created. You will literally not believe it until you see it. Standing in at 23” tall, 320 pounds, and with 12,000 watt peak music power handling, you will be hard-pressed to find something that will get in the ring with this heavyweight.
Carbon fiber and glass fiber dust cap with aluminum honeycomb center
Expanded polypropylene cone with mica filler for reduced mass and increased stiffness
FEA designed progressive roll spider with 10 AWG integrated tinsel leads woven in to allow for 2.5” of linear cone movement one way
900 ounce strontium ferrite magnet with extended magnetic field gap technology and aluminum shorting ring
6.5” voice coil with a flat wound, long-excursion design incorporating 2.5” of x-max and 17 AWG high temperature aluminum wire
Aluminum heatsink to maintain the optimum voice-coil temperature
I used to be into car audio back when it was cool. but anymore kids don’t have the money to spend on performance parts or car audio. All their money goes to more important things like drugs.
that being said I still like having a decent stereo in my vehicle but factory radios are getting better so it isn’t nearly as crucial as it used to be. I don’t listen to rap and I don’t compete in stereo competitions so 1 decent 12" sub is plenty for me
and on a side note, that thing has to sound like absolute shit. a 15" sub has trouble hitting anything but the lowest notes… and ive heard a couple setups back in the day that had 18" subs… you couldnt even hear it so much as you could feel it. Fuck all that. Sound quality > noise.

That subwoofer (the large one with the man standing next to it) was built by Richard Clark. It was run using something like 10,000 watts of rms power. It is in a bread truck and used the cargo area for the enclosure. this was done at least 5-7 years ago. The cone was 60" or 5 five feet!
For spl competitions, competitors use test tones to “burp” the systems. Basically the car is designed to amplify a specific frequency. The “burp” usually lasts about 3-5 seconds. Forget about low distortion here, the amplifiers get fully clipped to drive the subs.
Dynamic low frequency peaks require huge amounts of power for them to be heard at a linear level with the rest of the source material. That is why we see biggger and bigger amplifiers on bigger and bigger woofers.
