Abstract: An audio speaker for projecting sound into a listening space having an on-axis includes a frame supporting at least two drivers radially arrayed in a plane substantially perpendicular to the on-axis. The at least two drivers may be electrically connected to operate in common acoustic phase, substantially the same size, mid-range drivers, and/or may include at least one rearward facing driver. The audio speaker may also include an on-axis driver, or an inner driver positioned substantially at a point where a first line drawn perpendicularly through a face of a first driver of the at least two drivers and a second line drawn perpendicularly through a face of a second driver of the at least two drivers converge. The inner driver may be a high frequency driver, for example, a tweeter, and a face of the inner driver may be substantially perpendicular to the on-axis.

Abstract: An audio speaker for projecting sound into a listening space along an on-axis and off-axis includes a frame supporting drivers arrayed in a plane for projecting sound off-axis, and a waveguide attached to the frame and supporting an inner driver for projecting sound on-axis. The waveguide at least partially defines a chamber for loading the at least two drivers and the plane is substantially perpendicular to the on-axis. Another audio speaker for projecting sound into a listening space along an on-axis and off-axis includes a three-dimensionally printed unibody supporting at least two drivers arrayed in a plane for projecting sound off-axis. Still another audio speaker includes a frame supporting one group of drivers arrayed in a plane for projecting sound off-axis and a waveguide supported by the frame such that the waveguide extends in an on-axis direction and includes a front portion having an uninterrupted exterior surface.

Abstract: An audio speaker includes a frame or manifold supporting a plurality of drivers electrically connected to operate in common acoustic phase. The plurality of drivers includes an inner group of drivers and an outer group of drivers at least partially surrounding the inner group of drivers and the outer group of drivers includes at least two drivers with at least one the two drivers being a rearward facing driver.

Abstract: An audio speaker includes an enclosure having a coupling chamber and a loading chamber, at least m radiating drivers, and at least one and no more than m?1 loading driver(s) in communication with the coupling chamber, wherein m is at least two and each radiating driver operates in common acoustic phase. The coupling chamber acts to couple the at least m radiating drivers and the at least m?1 loading driver(s), for example, and the loading chamber acts to load the loading driver(s). The at least one and no more than m?1 loading driver(s) may have a higher sensitivity than the at least m radiating drivers and the at least m radiating drivers may be arranged within the enclosure to minimize a volume of the coupling chamber. In other embodiments, the at least one and no more than m?1 loading driver(s) may be other types of inducers (e.g., an undriven loading driver(s), a drone cone, a port, or combinations thereof).

Abstract: An audio speaker includes a frame or manifold supporting a plurality of drivers electrically connected to operate in common acoustic phase. The plurality of drivers includes an inner group of drivers and an outer group of drivers at least partially surrounding the inner group of drivers. An electrical input of the outer group of drivers may be delayed relative an electrical input of the inner group of drivers depending on several factors including the selected frame on which the plurality of drivers is mounted.
