Down sizing parallel boundary arrays?

["Paul Jacobson" thebrunswicktwitcher]

Hi all,

I'm wondering if there was any limit to how far the barriers could be
reduced before they ceased to be effective? It seems the forward edge
setback requirement is minimal - around 0.5 to 1.5 inches. The length
of the barrier behind the capsule seems to be designed to function
primarily as a mount for the mic.

  I wonder if this rear offset could be reduced to 1.5 to 2 inches
without effecting the rig performance?

The same question extends to the height of the barrier. Could this
dimension be reduced without negative effect?

cheers
Paul
