Modified Zwislocki coupler

Some months ago, I managed to construct a modified(simplified) Zwislocki coupler:

 entirely out of a pulp material and later finished w/ resin.
 [for 0.3" microphones only]

Still its accuracy was little off from IEC-711 due to the acoustic impedance mismatch in the mid frequency range. I need to further enhance the design.

  1. Where can we find more details on a Zwislocki coupler? a model or a schematic / paper with the design...
