A commenter from our previous humongous woofer post points out another contender for biggest-sub-ever - Enter(literally) the Matterhorn -
The most powerful sub ever created. It was born out of a
military request and is housed in a 20' x 8' x 8' shipping container.
40 drivers, 40 kwatts of self powered and built in generator to boot.

I've seen a much larger rig used for vibration testing of military aircraft - the amplifier was the size of several filing cabinets, and had rows and rows of water cooled power transisters. I'm not sure you can still call it a subwoofer when the "speaker" is a concrete floor large enough to bolt an aircraft to though.
I imagine this is used for something similar on a smaller scale.
(first page of conference paper linked) which is capable of frequencies as low as 4 Hz, 130 dB SPL @ 2 m. I'm not sure of the current state of repair--several years ago while I was a co-op there, I removed a bird skeleton from one of the "speakers", and the paddles used to generate the lowest frequencies were sticking after several years in the Georgia heat and humidity, but it was still pretty impressive. I'm not having any luck finding pictures though. May be some in the paper, but my AIAA member number is at home so I can't check.

I hope those opposing speakers are phased correctly, because otherwise it'll be the most powerful and also the quietest subwoofer.
If the speakers fired downward, then maybe they could have been testing (more) ways to clear mine fields.

Military "testing" on the psychological effect of blasting annoying songs at barricaded-in "soft-targets", ala Waco.
Blast music loud and strong enough to deprive the enemy of sleep, making them sleepy, slow to react, and not think straight.

Just to note, the proper conjugation in this context is "EVAR??", in caps, as opposed to "evars!?"
Just saying :)

The Georgia Tech Research Institute has a sonic boom simulator:

Here's some more info from its designer:
