ABSTRACT:
An acoustic crossover speaker enclosure comprising a multi-sided box having an apertured baffle supporting a horn which in conjunction with the interior of the box defines an air chamber. The horn is supported in an upright position such that the throat of the horn opens at the baffle end of the box where the front end of a driver projects into the horn throat, while the back side of the driver projects into the air chamber of the box. The horn opens at the top end of the box wherein sound waves emitted from the mouth of the horn are laterally reflected by means of a sound deflector panel. The air chamber transmits sound from the rearward side of the driver to a bass reflex port in one wall of the box such that a sound radiated from the rear of the driver may be added to the sound emitted from the front of the driver.
