<p>A frequency response compensation system for use with a planar diaphragm speaker mounted in an architectural wall, ceiling or sealed enclosure having a depth dimension limited by the interior depth of the ceiling, wall or enclosure. The compensation system combines signals derived from a modified high-pass filter stage, an unmodified signal path, and a gyrator stage so as to phase-interact with one another and provide a complex transfer function. An underdamped high-pass filter stage further enhances low bass performance. The frequency compensation system includes a main circuit board and a series of daughter boards that are adapted to be releasably connected to the main board. Each of the daughter boards contains a set of passive components having different component values that determine the specific response parameters of the various stages and circuits of the compensation system and is optimized for a specific planar speaker and enclosure combination. A multi-section switch for selecting between different sets of component values may be substituted for the daughter boards. <IMAGE></p> |
