Abstract: A Multiple Aperture Device (MAD) for directing sound from a low-frequency transducer. The MAD includes a front face, a rim, a bulb, and a plurality of walls. The front face has a plurality of apertures. The rim has a circumference which matches a circumference of a perimeter of the low-frequency transducer. The bulb covers a center of a diaphragm of the low-frequency transducer. The plurality of walls define cavities between the diaphragm of the low-frequency transducer and the plurality of apertures. The plurality of walls and the plurality of apertures define a spatial response in both horizontal and vertical planes for desired radiation patterns of sound produced by the low-frequency transducer.

Abstract: This invention relates to a line-array loudspeaker that is configurable to meet the acoustic requirements of a venue. In one embodiment, the line-array includes a combination of far-field and near-field loudspeaker modules which are selectively fixedly connected to each other. Each module includes a first loudspeaker element and a second loudspeaker element. Each of the first and second elements includes a high-frequency transducer assembly and a low-frequency transducer assembly. The far-field modules and the near-field modules are fixedly connected using a rigging system to provide a smooth and continuous transition from a first splay angle to a second splay.

Abstract: A transformer saturation compensation circuit for loudspeakers in embodiments of the invention may include one or more of the following features: (a) a transformer with a primary winding and a secondary winding electrically coupled to an output, (b) a high pass filter, (c) a current dependent resistive load electrically coupled in parallel with the capacitor and electrically coupled to an input, (d) a switch located at the primary winding electrically coupled to the capacitor and the resistive load, the switch being rotatable to each of the taps, where the current dependent resistive load provides saturation compensation for different loudspeaker configurations without requiring changes to a highpass filter cutoff frequency, and (e) a resistive load electrically coupled in parallel with the current dependent resistive load and the capacitor.

Abstract: Offset baffles are provided in a speaker for acoustic signal arrival synchronization. The speaker includes an enclosure. The enclosure includes a first side positioned at an angle with respect to a horizontal axis or plane. The first side includes an upper portion and a lower portion. The upper portion and the lower portion are offset from one another by a first offset in a first direction and a second offset in a second direction. The first offset in the first direction and the second offset in the second direction define a vent extending across a width of the first side. The vent is positioned above a low-frequency transducer and below a high-frequency transducer. The low-frequency transducer is mounted to the lower portion and generates a first acoustic signal within a first frequency range. The high-frequency transducer is mounted to the upper portion and generates a second acoustic signal within a second frequency range.
