Abstract
A folded horn enclosure including a unitary throat and horn pathway which is optimized for ⅛th space placement when operated as a stacked pair. The enclosure uses at least 2 different flare rates and is suitable for standing vertically and horizontally, and further allowing stacking of 2 enclosures to form a full-sized corner horn.
Claims9
In a folded horn loudspeaker for vertical or horizontal placement,
- an enclosure comprising:
- an assembly of baffles defining a back chamber and a unitary horn pathway comprising two directional changes,
- said back chamber adapted and arranged to house at least one driver, said each driver being mounted to face rearwardly, said back chamber adapted with at least one throat opening cooperating with said each driver to transmit sound waves to said pathway,
- said pathway further comprising an outwardly disposed baffle arranged vertically and in a basal angle to cooperate in proximate relation with a corner formed by two walls and a floor or ceiling, said baffle further providing a full channel reflective surface,
- said pathway having at least two different flare rates and begins at the rear of said enclosure and proceeds perpendicular to a central axis of said enclosure,
- said pathway further progressing along a side of said back chamber and exhausts frontwardly on one side of a front baffle.

A folded horn enclosure comprising:
- an assembly of vertically arranged baffles defining a back chamber and a unitary horn pathway, the rearmost said back chamber baffle being adapted with at least one throat opening therein,
- said assembly further defined as having outer side baffles arranged in an oppositely disposed spaced plane parallel to a central axis of said enclosure, said back chamber being further defined by one of said outer side baffles,
- said pathway having a throat section and a terminal section, each said section having at least one different flare rates defined by baffles, and said pathway changing direction in between said sections,
- said pathway is further defined having two full channel reflecting baffles to turn said pathway, said pathway propagating from and along the rear plane of said enclosure around one side of said back chamber,
- said throat section being arranged perpendicular to a central axis of said enclosure and flaring vertically,
- said terminal section being partially defined by a said outer side baffle, and said flaring rate thereof being defined by at least one baffle of said back chamber and thereby flaring horizontally,
- said enclosure frontally being proportioned more wide than tall, with said pathway exhausting at the front of said enclosure, and
- means for completing said enclosure.
