Newsflash, an earthquake has been detected in __________ XD.
ThyDntWntMusic, post a video up on youtube when you get it up and running!!

here's one video someone made at the car show on Saturday, and there's another video on the way soon apparently.
YouTube - Loud Laser
I'm in Adelaide btw.
it ended up doing 146.7dB on music (at 52Hz) and does nearly 142dB at 20Hz.

It's probably not a good idea to be IN the car when playing it back at that level 🙂.
Thats some excellent work, very unique!
But 145db (even at peaks) for 1 minute plus, you will badly damage your hearing, tinnitus is really crap! 🙁

Dayum, thats insane!! Looks awesome too!
Im in Perth so will probably never see that monster.. 🙁

so apparently this isn't a transmission line? not according to me, according to others.
apparently it doesn't have enough port area to be a transmission line, and its a very high tuned box instead :/

I wouldn't've said it's a standard TL either. Not sure what it is, though - there's that many drivers that ones of each distance from the mouth will see a different tuning, so it would probably be difficult to simulate what's happening.
If it was me, I'd try blocking the port: below whatever tuning it is, the drivers will unload completely, giving lots of excursion, but relatively little output.
If you could get an impedance curve of the subwoofer as a whole, we might be able to see what's going on.
