It consisted of 72 EMIT tweeters, 24 EMIM midrange drivers, and twelve 12-inch polypropylene woofers in four towers. Nudell left to form Genesis Technologies, a high-end loudspeaker company, founded in Seattle in 1991. [2] Genesis' original flagship system, the 1.2, retailed for US$235,000, [3] and is basically an updated Infinity IRS system. [4]
Eminence, an American speaker company who was also participating in the discussions, designed a custom 12-inch driver to meet the requirements: the LAB12. The LAB Sub, also called the LAB horn, was a heavy subwoofer optimized for operation as four enclosures strapped together in a 2×2 "cube" configuration, to increase the effective mouth size ...
The former Jensen Radio Manufacturing Company was founded in 1927 by Peter Laurits Jensen, the co-inventor of the first loudspeaker, in Chicago, Illinois.The company gained popularity in its early years, rising to its peak in the mid 1940s when Jensen speakers were selected to be used in the first production of a guitar amplifier by Fender Musical Instruments Corporation.
Fitz Special. John Henry Fitzgerald, an employee of Colt Firearms from 1918 to 1944, first came up with the Fitz Special snubnosed revolver concept around the mid-1920s, when he modified a .38 Special Colt Police Positive Special revolver, [5] by shortening the barrel to two inches (5.1 cm), shortening the ejector rod, bobbing the hammer spur, rounding the butt, and removing the front half of ...
Three versions of this breech-loading rifled naval gun were produced, the 6-inch/47 Mark 16 Mod 0, the 6-inch/47 Mark 16 Mod 1, and 6-inch/47 Mark 17. "6-inch /47" refers to a bore diameter (caliber) of 6 inches (152 mm) and a bore length of 47 calibers (ie 47 × 6 inch; 23 feet 6 inches (7.16 metres). "Mark 16" indicates it is the 16th design ...
Constant-voltage speaker systems are also commonly referred to as 25-, 70-, 70.7-, 100 or 210-volt speaker systems; distributed speaker systems; or high-impedance speaker systems. In Canada and the US, they are most commonly referred to as 70-volt speakers. In Europe, the 100 V system is the most widespread, with amplifier and speaker products ...
In some instances, the powder may not have even been fully burned in guns with short barrels. So, the muzzle velocity of a 2-inch (51 mm) barrel is less than that of a 4-inch (100 mm) barrel, which is less than that of a 6-inch (150 mm) barrel. Large naval guns will have high length-to-diameter ratios, ranging between 38:1 to 50:1. This length ...
A gauge theory of elementary particles is a very attractive potential framework for constructing the Grand Unified Theory of physics. Such a theory has the very desirable property of being potentially renormalizable—shorthand for saying that all calculational infinities encountered can be consistently absorbed into a few parameters of the theory.
