If sound the sound waves from 2 pairs constructively interfere the amplitude should double which means a 6dB increase.

What distance does hella say they measure them at?
its actually a little less than that. a doubling of source = 3db increase.

10 * log10 (2) = 3.01 dB, where 2 is the double in power (volume).

agreed on the distance though, as that perceived volume will change.
