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]
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.
The left and right surround speakers in the bottom line create the surround sound effect. 5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres. [1] It uses five full-bandwidth channels and one low-frequency effects channel (the "point one"). [2]
All speaker drivers have a means of electrically inducing back-and-forth motion. Typically there is a tightly wound coil of insulated wire (known as a voice coil) attached to the neck of the driver's cone. In a ribbon speaker, the voice coil may be printed or bonded onto a sheet of very thin paper, aluminum, fiberglass or plastic.
Hi-fi speakers are a key component of quality audio reproduction.. High fidelity (often shortened to hi-fi or, rarely, HiFi) is the high-quality reproduction of sound. [1] It is popular with audiophiles and home audio enthusiasts.
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]
Meyer Sound Laboratories is an American company based in Berkeley, California that manufactures self-powered loudspeakers, multichannel audio show control systems, electroacoustic architecture, and audio analysis tools for the professional sound reinforcement, fixed installation, and sound recording industries.
