Hi-fi + Home cinema speakers

A loudspeaker (or "speaker") is an electroacoustic transducer that produces sound in response to an electrical audio signal input. Non-electrical loudspeakers were developed as accessories to telephone systems, but electronic amplification by vacuum tube made loudspeakers more generally useful. The most common form of loudspeaker uses a paper cone supporting a voice coil electromagnet acting on a permanent magnet, but many other types exist. Where high fidelity reproduction of sound is required, multiple loudspeakers may be used, each reproducing a part of the audible frequency range. Miniature loudspeakers are found in devices such as radio and TV receivers, and many forms of music players. Larger loudspeaker systems are used for music, sound reinforcement in theatres and concerts, and in public address systems.

Center speaker

Der Name des Center-Lautsprechers verrät schon, dass er das Zentrum der Mehrkanal-Anlage bildet. Das bedeutet für den Schallwandler nicht nur generelle Höchstleistung, sondern auch, dass ihm gesonderte Aufgaben übertragen werden, dessen spezifische Anforderungen er bravourös zu meistern hat. Einer der wichtigsten Eigenschaften, die ein Center mitbringen muss, ist eine exzellente Wiedergabe von Sprachen und Stimme. Sowohl die Dialoge im Film als auch die Vokalstimmen beim Musikkonzert konzentrieren sich bei Mehrkanal-Tonspuren im Center-Lautsprecher.

Bass reflex

A Bass reflex system (also known as a ported, vented box or reflex port) is a type of loudspeaker enclosure that uses the sound from the rear side of the diaphragm to increase the efficiency of the system at low frequencies as compared to a typical closed box loudspeaker or an infinite baffle mounting.

Nominal power

Die Nennbelastbarkeit des Lautsprechers, gemessen in W (Watt), gibt an, welche elektrische Leistung der Lautsprecher im Dauerbetrieb aufnehmen kann. Sie wird mit einem definierten Rauschsignal ermittelt. Dieses Rauschsignal soll ein typisches Musikprogramm simulieren. Es ist dadurch gekennzeichnet, daß die hohen Frequenzen viel schwächer vertreten sind als die tiefen.
