When you're trying to picture how loud this 180.5db subwoofer that set the world record for the loudest sound for a single sub is, you can't picture jet planes or chainsaws or firecrackers. No, you need to go a bit higher—into the realm of atomic bombs and nuclear disasters. So yes, this Digital Designs 9918Z 18-inch subwoofer that's powered from four Stetsom KD amps at 26,000 watts is a rolling nuclear explosion when it crunks down your street. That'll show the kids (and the old man with the heart condition) who's boss. [Audio Junkies]
DISCUSSION
At first I was skeptical. Then open-minded. Then impressed. Then I read all the conditions and stipulations. Now I think I am not as impressed, but I definitely think it can be done...but it wouldn't be "that" loud probably outside the car, a reasonable distance away. A single, smaller subwoofer might really be the way to go.
Hey, even the pistol shrimp makes a 200+ dB sonic boom, and bubbles that reach the surface temp of the sun! (But it only kills something a few inches away.)
