Wireless speakers are loudspeakers that receive audio signals using radio frequency (RF) waves rather than over audio cables. The two most popular RF frequencies that support audio transmission to wireless loudspeakers include a variation of WiFi IEEE 802.11 , while others depend on Bluetooth to transmit audio data to the receiving speaker.
Originally, the Model 10 was sold to law enforcement only. The concept of this shotgun was quite interesting to many police agencies who adopted the Model 10 in the late 1960s and early 1970s; however, most of the agencies found many shortcomings, and ultimately ceased using the Model 10. The most common problem was the failure to cycle correctly.
This list of car audio manufacturers and brands comprises brand labels and manufacturers of both original equipment manufacturer (OEM) and after-market products generally related to in-car entertainment that already have articles within Wikipedia.

A woofer or bass speaker is a technical term for a loudspeaker driver designed to produce low frequency sounds, typically from 20 Hz up to a few hundred Hz. The name is from the onomatopoeic English word for a dog's deep bark, "woof" [1] (in contrast to a tweeter, the name used for loudspeakers designed to reproduce high-frequency sounds, deriving from the shrill calls of birds, "tweets").
Originally conceived as a domestic hi-fi speaker, the NS-10 was designed by Akira Nakamura and launched in 1978. [2] [3] While the speaker was poorly received, recording engineers came to rely on the NS-10 as a benchmark. The model was discontinued in 2001. [2] The NS-10 was recognised for its ability to reveal shortcomings in recordings. [4]
The 122RV was the same model, but with an additional reverb amplifier, which fed through to a separate static speaker. [30] A slightly smaller version, the 33-inch (840 mm) 142 was available. [ 31 ] Hammond-Suzuki currently manufacture the 122A, a straight reissue of the 122, and the 122XB, which contains a modern 11-pin adapter, an IECC mains ...
From about 1900 to the 1950s, the "lowest frequency in practical use" in recordings, broadcasting and music playback was 100 Hz. [9] When sound was developed for motion pictures, the basic RCA sound system was a single 8-inch (20 cm) speaker mounted in straight horn, an approach which was deemed unsatisfactory by Hollywood decisionmakers, who hired Western Electric engineers to develop a ...
The Belgian military did not experience difficulties with their Chauchats in 7.65mm Mauser and kept them in service into the early 1930s, as did the Polish Army. Conversely, the Chauchat version in U.S. .30-06 made by "Gladiator" for the A.E.F., the Model 1918, proved to be fundamentally defective and had to be withdrawn from service.
