Is there any forward gain in a pr of spaced drivers due to the "doublet effect" over a single point source?
Or, is the acoustic energy from the nulls just lost in many unwanted lines?  

In other words... if I took two drivers spaced horizontally would I see forward( and rear) gain at a certian freq then loose the gain to an omni pattern as the freq drops where the two begin to act as one source?

Hmm... I may have to set up two boxes outside and play around.

Good idea.

Forward gain would be related to the frequency, spacing, and listening angle to the two sources.
