Design

The driver will be a push-pull mid/tweeter planar. Overall, the magnet system is the same as is used by Patten (2), Gold Ribbon Concepts (4) and Carver in their ALS. Unlike the Patten or GRS (but like numerous others) the driver will be slightly corrugated horizontally to increase longitudinal stiffness and impede the generation of standing waves. Also unlike both of these, multiple conductors will be in each gap. Where Patten uses thin wire and packing tape, here ~0.3 mil Al foil will be used and bonded to the diaphram film (Kapton). The basic system will look from the top something like:

The diaphram is be held together by an adjustable frame so that the horizontal tension can be adjusted. The frame can be made of MDF (or particleboard) or maybe hardwood.
