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.
Early speaker from Vega Labs. Cerwin-Vega was founded as Vega Associates [4] (with later name changes to Vega Laboratories and then Cerwin-Vega) by aerospace engineer Eugene J. "Gene" Czerwinski (1927–2010) in 1954, [4] and became noted for producing an 18" speaker capable of producing 130 dB in SPL at 30 Hz, an astonishing level during its time.
Sensurround involved the installation of large, low frequency, horn-loaded speakers which contained specially designed 18-inch Cerwin-Vega Model 189 ES drivers in custom black wood cabinets. Three horn configurations were available, Model-C (Corner), Model-W (Folded Bass Bin) and Model-M (Modular).
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 ...
An example of a subwoofer that uses a bass horn is the Bassmaxx B-Two, which loads an 18-inch (45 cm) driver onto an 11-foot (3.4 m) long folded horn. [51] Folded horn-type subwoofers can typically produce a deeper range with greater efficiency than the same driver in an enclosure that lacks a horn. [51]
Loudspeaker enclosures range in size from small "bookshelf" speaker cabinets with 4-inch (10 cm) 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 18-inch (46 cm) or even 21-inch (53 cm) speakers in huge enclosures which are designed for use in ...
He "spearheaded" the effort which in February 2002 resulted in Danley posting the design of a 45 in × 45 in × 22.5 in (114 cm × 114 cm × 57.1 cm) snail-shell folded-horn subwoofer using two 12-inch drivers at the horn throat.
The birth of the modern transmission line speaker design came about in 1965 with the publication of A.R. Bailey's article in Wireless World, “A Non-resonant Loudspeaker Enclosure Design”, [16] detailing a working Transmission Line. Bailey followed up his first article with a second one in 1972. [18]
