Once I was experimenting with 12" solo-barics.. And when fast to face, about 18" apart, I was able to kill sound.. Like less than 1/10 of the bass was coming out.. And the subs were working at full travel (with roughly 600w rms on each sub).. Freaky huh?!

The reason the sound was killed is because the sound waves simply canceled each other out. Since they were the same brand/size subs, they were probably emmiting a near exact sound wave. If two soundwaves with the same frequencies/wavelengths hit each other head on (each moving in an opposite direction from the other), they will cancel each other out. If both waves were moving in the same direction and interesected, then the sound would be amplified.

(sorry for the long explanation, we just learned this in my highschool physics class, so it's fresh on my mind)
