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 ...
Speaker wire is a passive electrical component described by its electrical impedance, Z. The impedance can be broken up into three properties which determine its performance: the real part of the impedance, or the resistance, and the imaginary component of the impedance: capacitance or inductance. The ideal speaker wire has no resistance ...
A speaker grille (or speaker grill) is usually found in front of many consumer and industrial loudspeakers, and consists of either a hard or soft screen / grille mounted directly over the face of the speaker driver. Its main purpose is to protect the driver element and speaker internals (and possibly other audio components) from foreign objects ...
Loudspeaker. The hole below the lowest woofer is a port for a bass reflex system. A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer [1] : 597 that converts an electrical audio signal into a corresponding sound. [2] A speaker system, also often simply referred to as a speaker or loudspeaker ...
The electroacoustic mechanism most widely used in speakers to convert the electric current to sound waves is the dynamic or electrodynamic driver, invented in 1925 by Edward W. Kellogg and Chester W. Rice, which creates sound with a coil of wire called a voice coil suspended between the poles of a magnet. There are others which are far less ...
A speaker terminal is a type of electrical connector often used for interconnecting speakers and audio power amplifiers . The terminals are used in pairs with each of the speaker cable 's two wires being connected to one terminal in the pair. Since speaker connections are polarized, the terminals are typically color-coded so that the positive ...
Horn loudspeaker. A midrange horn driver used in a home speaker system from Klipsch. The width of the front opening is roughly 46 cm. How a horn loudspeaker works. (A) compression driver (B) horn. A horn loudspeaker is a loudspeaker or loudspeaker element which uses an acoustic horn to increase the overall efficiency of the driving element (s).
Below the bottom woofer is a bass reflex port. 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.
