Klipsch
Klipsch Audio Technologies (also referred to as Klipsch Speakers or Klipsch Group, Inc.) is an American loudspeaker company based in Indianapolis, Indiana. Founded in Hope, Arkansas, in 1946 as 'Klipsch and Associates' by Paul W. Klipsch, the company produces loudspeaker drivers and enclosures, as well as complete loudspeakers for high-end, high-fidelity sound systems, public address applications, and personal computers. On January 6, 2011, Audiovox announced that the company had signed a "term sheet to purchase all the shares of Klipsch Group Inc". The sale was completed March 1, 2011. Horn loading Since its inception, Klipsch has promoted the use of horn-loaded speakers as part of its goal to produce speakers featuring: *High efficiency (more formally called "sensitivity"), meaning that they can be driven by relatively low-powered amplifiers *Low modulation distortion, which Paul Klipsch believed was very important *Wide dynamic range, meaning that they accurately reprod ...

Paul W Klipsch
Paul Wilbur Klipsch (March 9, 1904 – May 5, 2002) was an American engineer and high fidelity audio pioneer, known for developing a high-efficiency folded horn loudspeaker. Unsatisfied with the sound quality of phonographs and early speaker systems, Klipsch used scientific principles to develop a corner horn speaker that sounded more lifelike than its predecessors. The Klipschorn, which today is still manufactured and sold worldwide, proved popular. The resulting acoustics career of Klipsch spanned from 1946, when he founded one of the first U.S. loudspeaker companies, to 2000 when the Journal of the Audio Engineering Society published one of his papers. He died on May 5, 2002 at the age of 98. Fred Klipsch, former Klipsch owner and chairman and cousin to founder Paul Wilbur Klipsch, said, “Paul was a verifiable genius who could have chosen any number of vocations, but the world sounds a lot better because he chose audio.” Early life and education Klipsch's interest in ...

Hope, Arkansas
Hope is a city in Hempstead County in southwestern Arkansas, United States. Hope is the county seat of Hempstead County and the principal city of the Hope Micropolitan Statistical Area, which includes all of Hempstead and Nevada counties. As of the 2010 census the population was 10,095, and in 2019 the population was estimated at 9,599. Hope is the birthplace of two former Arkansas governors: Bill Clinton (who was also President of the United States from 1993 to 2001) and Mike Huckabee (who ran for the Republican presidential nomination in 2008 and 2016). Sarah Huckabee Sanders, daughter of Mike Huckabee, also born in Hope, was voted in as Arkansas's new governor on November 8, 2022, and will become governor in January 2023. History Hope began in 1873, when a railroad was built through the area. The town was named for Hope Loughborough, the daughter of a railroad executive. In the 1902-1903 timeframe, the St. Louis, San Francisco and New Orleans Railroad was built into town; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horn Loudspeaker
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. Another type is a woofer driver mounted in a loudspeaker enclosure which is divided by internal partitions to form a zigzag flaring duct which functions as a horn; this type is called a ''folded horn'' speaker. The horn serves to improve the coupling efficiency between the speaker driver and the air. The horn can be thought of as an "acoustic transformer" that provides impedance matching between the relatively dense diaphragm material and the less-dense air. The result is greater acoustic output power from a given driver. The narrow part of the horn next to the driver is called the "throat" and the large part farthe ...

Loudspeaker Enclosure
A loudspeaker enclosure or loudspeaker cabinet is an enclosure (often rectangular box-shaped) in which speaker drivers (e.g., loudspeakers and tweeters) and associated electronic hardware, such as crossover circuits and, in some cases, power amplifiers, are mounted. Enclosures may range in design from simple, homemade DIY rectangular particleboard boxes to very complex, expensive computer-designed hi-fi cabinets that incorporate composite materials, internal baffles, horns, bass reflex ports and acoustic insulation. Loudspeaker enclosures range in size from small "bookshelf" speaker cabinets with woofers and small tweeters designed for listening to music with a hi-fi system in a private home to huge, heavy subwoofer enclosures with multiple or even speakers in huge enclosures which are designed for use in stadium concert sound reinforcement systems for rock music concerts. The primary role of the enclosure is to prevent sound waves generated by the rearward-facing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woofer
A woofer or bass speaker is a technical term for a loudspeaker driver designed to produce low frequency sounds, typically from 50 Hz up to 1000 Hz. The name is from the onomatopoeic English word for a dog's bark, " woof" (in contrast to the name used for loudspeakers designed to reproduce high-frequency sounds, '' tweeter''). The most common design for a woofer is the electrodynamic driver, which typically uses a stiff paper cone, driven by a voice coil surrounded by a magnetic field. The voice coil is attached by adhesives to the back of the loudspeaker cone. The voice coil and the magnet form a linear electric motor. When current flows through the voice coil, the coil moves in relation to the frame according to Fleming's left hand rule for motors, causing the coil to push or pull on the driver cone in a piston-like way. The resulting motion of the cone creates sound waves, as it moves in and out. At ordinary sound pressure levels (SPL), most humans can hear down to abo ...

Tractrix
In geometry, a tractrix (; plural: tractrices) is the curve along which an object moves, under the influence of friction, when pulled on a horizontal plane by a line segment attached to a pulling point (the ''tractor'') that moves at a right angle to the initial line between the object and the puller at an infinitesimal speed. It is therefore a curve of pursuit. It was first introduced by Claude Perrault in 1670, and later studied by Isaac Newton (1676) and Christiaan Huygens (1693). Mathematical derivation Suppose the object is placed at (or in the example shown at right), and the puller at the origin, so is the length of the pulling thread (4 in the example at right). Then the puller starts to move along the axis in the positive direction. At every moment, the thread will be tangent to the curve described by the object, so that it becomes completely determined by the movement of the puller. Mathematically, if the coordinates of the object are , the of the pull ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acoustic Resonance
Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its ''resonance frequencies''). The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter, acoustic resonance can occur at frequencies outside the range of human hearing. An acoustically resonant object usually has more than one resonance frequency, especially at harmonics of the strongest resonance. It will easily vibrate at those frequencies, and vibrate less strongly at other frequencies. It will "pick out" its resonance frequency from a complex excitation, such as an impulse or a wideband noise excitation. In effect, it is filtering out all frequencies other than its resonance. Acoustic resonance is an important consideration for instrument builders, as most acoustic i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
