Danley was an early adopter of the Crown Tecron TEF (time-energy-frequency) audio analysis system, introduced in 1983, and he used a TEF-10 portable test rig to measure his audio experiments. At the request of the same documentary producer, in the 1990s Danley used a TEF-12 analyzer to assess the acoustics inside the Great Pyramid of Giza .
A line of studio monitor speakers was created in 1991. [15] In 1996, Yorkville introduced the "TX" line of concert touring loudspeakers. [14] In 2001, Yorkville contracted with designer Tom Danley to create the "Unity" line of loudspeakers which was introduced in 2003. The Unity design was licensed from Danley's company Sound Physics Labs. [17]
Hughes' third patent, his second with Altec, was a patent for a dipole and monopole surround sound speaker system which used indirectly aimed drivers added to the top of the usual front left and front right loudspeakers. [12] Altec brought the technology to market as the GT 5051R—a 3.1 system which included a center speaker and a subwoofer.
A horn loudspeaker is a loudspeaker or loudspeaker element which uses an acoustic horn to increase the overall efficiency of the driving element(s). A common form (right) consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air.
User's guide for a Dulcitone keyboard. A user guide, also commonly known as a user manual, is intended to assist users in using a particular product, service or application. It is usually written by a technician, product developer, or a company's customer service staff. Most user guides contain both a written guide and associated images.
Monsoon logo. Monsoon is a brand of loudspeakers, originally automotive speaker systems and later computer speakers.Monsoon was originally associated with OEM-sourced automotive audio speaker systems, notably supplied on a number of General Motors products and then later expanded onto other manufacturers such as Volkswagen.
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
By "very close" is meant in the predominantly direct, rather than reflected, sound field. A near-field speaker is a compact studio monitor designed for listening at close distances (3 to 5 feet (0.9 to 1.5 m)), so, in theory, the effects of poor room acoustics are greatly reduced.)
