Audio Systems speakers

An audio system speaker typically consists of a number of components. These include one or more source components, one or more amplification components, and (for stereo), two or more loudspeakers. In addition, different signal cables (analog audio, speaker, digital audio etc.) can be used to link these components. There are also a variety of accessories. These include specialized equipment racks, power conditioners, devices to reduce or control vibration, peripheral devices such as record cleaners, anti-static devices, and phonograph needle cleaners, and reverberation reducing devices such as speaker pads and stands, sound absorbent foam and soundproofing.

The interaction between the Audio loudspeakers and the room plays an important part in sound quality. Sound vibrations are reflected from walls, floor and ceiling, and are affected by the contents of the room. Room dimensions can create standing waves. There are devices for room treatment that affect sound quality. Soft materials, such as draperies and carpets, can absorb higher frequencies, whereas hard walls and floors can cause excess reverberation.
