A soundbar, sound bar or media bar is a kind of loudspeaker that projects audio tracks from a broad enclosure. It really is much wider than it really is tall, partly for acoustic reasons, and partly so that it could be mounted above or below a display device, e.g., above a computer monitor or under a home entertainment or television set screen. Basically, in a soundbar multiple speakers are located within a cabinet, which really helps to create surround sound and/or stereo effect. Another subwoofer is typically incorporated with, or enable you to supplement, a soundbar.
Early passive versions simply integrated left, centre and right speakers into one enclosure, sometimes named an “LCR soundbar”.
Altec Lansing introduced a multichannel soundbar in 1998 called the Voice Of The Digital Theatre or the ADA106. It had been a powered speakers that offered stereo, Dolby Pro-Logic and AC3 surround sound from the soundbar and another subwoofer. The soundbar housed four 3″ full range drivers and two 1″ tweeters as the subwoofer housed one 8″ dual voice coil driver. It used Altec Lansing’s side-firing technology and algorithms to supply surround sound from the sides, rear and front. This configuration eliminated the wiring of separate speakers and the area they might require.
Advantages and disadvantages
Soundbars are relatively small and will be easily positioned under a display, are simple to set up, and are generally less costly than other stereo sound systems. However, as a result of their smaller size and insufficient overall flexibility in positioning, soundbars usually do not fill an area with sound and separate-speaker stereo systems do.
To take advantages both from soundbar and stereo set system, some manufacturers produce soundbar hybrids where the soundbar represents left, center, and right speakers plus (wireless) subwoofer and rear-left and rear-right speakers. Sometimes producers make soundbars with left, center, and right speakers plus detachable charge rear-left and rear-right speakers.
Soundbars were mainly made to generate strong sound with good bass response. Soundbar consumption has increased steadily as the world has moved to flat-screen displays. Earlier television set sets and display units were generally CRT-based; hence the box was bigger, facilitating larger speakers with good response. But with flat-screen televisions the depth of the screen is reduced dramatically, leaving little room for speakers. Therefore, the built-in speakers lack bass response. Soundbars help bridge this gap. Manufacturers such as for example Bose, Pioneer, Polk, and Yamaha are leaders in the high-performance soundbar segment. Soundbars also eradicate the problem of inherent music loss, when sound emitted from the trunk of a TV or monitor immediately reflects off the beaten track behind the unit.
A soundbase is comparable to a soundbar but suitable for a TV to stand on. Because of the larger size, soundbases routinely have better bass sound than soundbars, unless the latter includes a separate subwoofer
