Wave field synthesis array plans

Plans are coming along for construction of the ALMWFSLA (pronounced "almwfslah"), or Absurdly Large Modular Wave Field Synthesis Loudspeaker Array. The modules will be 18" x 4.5" with an open-back enclosure. This will allow for a 4'-6" x 3' plane array, a full surround line array 11 feet in diameter, and many more fascinating configurations.

UPDATE: The modules are 20" x 5" with a sealed enclosure. Open-back was a bad idea; the primary function of the enclosure is to mitigate cancellation from the backward wave, and make the speaker behave more like a true point source.

Here's a teaser:
