It's no dubstep gun, but this DIY "bass cannon" combines some speaker guts and an Airzooka for a portable party that rides on your shoulders -- or at your hip, ready to fire some crazy beats any time the need arises.
To call it a "bass" cannon is kind of unfair. The Airzooka specifically accentuates bass -- bass is omnidirectional -- but the Airzooka body does channel all of the sound in one specific direction, meaning that even if the music is playing, it's playing much louder for anyone in the line of fire from the front opening. We should also note that for all the dubstep jokes here, this works just as well for any other type of music you love (or hate), so it can be just as effective a toy (or weapon) to blast the jams to your friends in the backyard, or give those noisy neighbours a taste of their own medicine.
