Planot technology is the solution.

The shape of things to come...

Previous attempts to create full-range speakers utilized the traditional driver modeled after the human eardrum; but the eardrum is a receiver, not a producer, of sound. The traditional driver moves back and forth like a piston in a car engine (pistonic movement). Planot breaks with that tradition. Planot approaches sound production from a purely mechanical perspective, not from a notion of mirroring natural design.

The old cone-shaped diaphragm is stretched, metaphorically, into a tall vertical shape and joined together along its long edge. The diaphragm pivots about its long axis. The tensile forces that cause old-style speakers to flex and distort are bypassed. The torsional forces that act on the Planot diaphragm are dissipated along its length and volume.

As far as air is concerned, the Planot driver is a one-sided surface. There is no back side to the Planot driver. There is no phase cancellation from the back-wave because there is no back-wave as in a traditional pistonic driver. There is no need for a box for the containment of a back-wave.

The Planot driver's long faces' width is tailored to the highest frequency it is to reproduce. As with a full-range driver this may be 3/4" wide to accommodate a 18,000 Hz sound. A triangular cross section provides the best balance of several important parameters; it has a high angle of attack; a large part of its mass is concentrated near the axis of rotation; a triangle is the most rigid structure constructed of planes.

A typical Planot driver would be triangular in cross section and 48 inches long, with each face 3/4 inches across the short dimension. This means that surface area of each face is equivalent to that of a six-inch cone driver, and the total surface area of three sides is approximately that of a 10-inch cone.

The Planot has no box, no crossover, no diaphragm flexing and no surround or spider. The traditional compromises of loudspeaker design have been eliminated. Just the basics are left. The Planot speaker is the most minimum of machines between the sound and your experience.
