Abstract: A low frequency exponential folded horn enclosure employing a bifurcated horn terminal pathway and a single driver with a bifurcated throat channel, with driver access from the top or bottom of the enclosure. The horizontal “butterfly” throat is located at the rear of the enclosure and expands vertically, and the vertically arranged bifurcated horn terminus exhausts in a mostly forward direction on opposite sides of the back chamber which is reflex-ported; said ports arranged to each exhaust into the channel folds at each respective corner of the terminal horn channel.

Abstract: A middle to high frequency straight pathway horn with wide horizontal dispersion characteristics having extended terminus side walls which approach a perpendicular angle compared to the horn axis which are further extended by a rearwardly divergent angled or curved surface from the terminus frontal plane to reduce the deleterious effects of horn mouth, edge, and baffle diffraction, allowing for traditional front baffle mounting or free-standing use. Modular baffle elements allow the invention to be configured for the further reduction of diffraction effects in a variety of applications.

Abstract: A folded horn enclosure including a unitary throat and horn pathway which is optimized for ?th 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.

Abstract: A low frequency exponential bass horn enclosure suitable for use in a front-loaded or rear-loaded configuration, intended for corner placement, with driver access from the back. The unitary horn pathway exhausts upward along the dihedral axis formed by the vertical walls of the corner and the ungular form of the triangle-based enclosure.

Abstract: A low frequency folded horn enclosure intended for use in proximity with at least one planar surface with access to the horn throat from the top of the enclosure. The horn is bifurcated at the throat and folds horizontally around a central trapezoid-shaped columnar back chamber which includes a phase-inverting means. The throat channel expands vertically to the single fold and expands vertically and horizontally to the horn mouth, maximizing back chamber volume within the constraints imposed by footprint size, frequency response, and driver characteristics.

Abstract: A low frequency exponential bass horn enclosure employing a bifurcated horn pathway and twin throats, convertible to a variety of front-loaded or rear-loaded configurations without modifications by the use of interchangeable parts, with driver access typically from the front. Optimized for corner placement but fully enclosed horn channel allows for floor or wall use. The horizontal “butterfly” throat is located at the rear of the enclosure and expands vertically, and the vertically arranged horn terminus exhausts in forward-canted splay angles around a partially rectangular back chamber.

Abstract: A low frequency exponential bass horn enclosure employing a large area unitary throat pathway, bifurcated at a substantially parabolic rearward channel wall, convertible to a front-loaded or rear-loaded configuration by the use of interchangeable parts, with driver access from the front. Intended for corner placement, however, fully enclosed horn channel allows for floor use. The axially-centered throat expands vertically, exhausts rearward, and is bifurcated at the back of the enclosure with two hard reflection points, comprising a single fold, in which the vertically arranged horn terminus exhausts with a forward-canted splay angle around a partially rectangular back chamber.

Abstract: A low frequency exponential/hyperbolic hybrid folded horn enclosure intended for use in proximity with at least one planar surface, such as a floor, ceiling, or wall, with access to the horn throat from the top of the enclosure. The horn is bifurcated at the throat and folds horizontally around a central trapezoid-shaped vertical back chamber which is reflex ported for enhanced low frequency response below the frequency cutoff of the horn. The back chamber outer sides define part of the horn channel, resulting in a relatively simple structure with a small footprint and no void internal space. The throat exponential expansion cross-sectional area is consistently maintained while the proportions of the throat channels are elongated to the height of the enclosure.

Abstract: A low frequency exponential horn enclosure intended for corner use with access to the horn throat and entire volume of the back chamber from the top of the enclosure, allowing operation as either a front or back loaded horn. The horn is bifurcated at the throat and folds horizontally around a central triangle-shaped columnar back chamber, the sides of which form part of the horn channel, forming a simple structure with little void space.
