Horn-loaded compression drivers can achieve very high efficiencies, around 10 times the efficiency of direct-radiating cone loudspeakers. They are used as midrange and tweeter drivers in high power sound reinforcement loudspeakers , and in reflex or folded-horn loudspeakers in megaphones and public address systems .
Western Electric Co., Inc. was an American electrical engineering and manufacturing company that operated from 1869 to 1996. A subsidiary of the AT&T Corporation for most of its lifespan, Western Electric was the primary manufacturer, supplier, and purchasing agent for all telephone equipment for the Bell System from 1881 until 1984, when the Bell System was dismantled.
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.
A horn tweeter is any of the above tweeters coupled to a flared or horn structure. Horns are used for two purposes — to control dispersion, and to couple the tweeter diaphragm to the air for higher efficiency. The tweeter in either case is usually termed a compression driver and is quite different from more common types of tweeters (see above).
Lansing Manufacturing was the only firm selling them as Shearer Horns. In 1936, the Shearer Horn received the Academy Scientific and Technical Award from the Academy of Motion Picture Arts and Sciences. Lansing Iconic JBL TI 5000, a 3-way system with a 30 cm bass driver and a titanium membrane tweeter, built from about 1992 to 1999. With a ...
The voice switching fabric plan was similar to that of the earlier 5XB switch in being bidirectional and in using the call-back principle. [clarification needed] [citation needed] The largest full-access matrix switches (the 12A line grids had partial access) in the system, however, were 8x8 rather than 10x10 or 20x16.
High-frequency drivers were likely made by Western Electric. [12] Altec Lansing introduced the 604, which became their most famous coaxial Duplex driver, in 1943. It incorporated a high-frequency horn that sent sound through a hole in the pole piece of a 15-inch woofer for near-point-source performance. [13]
The cylindrical driver unit under the horn contained the diaphragm, which the voice coil vibrated to produce sound through a flaring horn. It produced far more volume from a given amplifier than a cone speaker. Horns were used in virtually all early PA systems, and are still used in most systems, at least for the high-range tweeters.
