Well with two sources a half wl apart, you get +6dB over one on axis only.
Think about a polar plot, the diameter is level vs angle and the area within the polar circle summed is the total acoustic power.
Two sources that far apart produce a figure 8 pattern who's peak value is +6dB on axis but the area enclosed by the polar circle is only 3 dB more than each source individually.
Move those sources to less than 1/4 wl apart and now you have a circle who's diameter is +6dB and the total energy is now 6dB greater than one was.
acoustic power
1+1=2
or
1+1=4
depends on the spacing and location
