A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded ...

L-Acoustics later introduced other products, including the ARCS Constant Curvature Array (1995), dV-DOSC modular line source (1999), Kudo with K-Louver variable directivity (2005), P Series self-powered coaxials (2006), SB28 subwoofer with laminar vents and LA4 and LA8 amplified controllers (2007). The company also introduced their Soundvision ...
1969 – JBL components deliver sound at Woodstock and many other rock festivals; 1973 – 4300 Series launched, including the first 4-way speaker; 1975 – 4682 Model Line Array Strongbox; 1979 – Technology diamond surround for control of high frequency resonances in; 1979 – Development of Symmetrical Field Geometry (SFG)
Sound from an array spreads less than sound from a point source, by the Huygens–Fresnel principle applied to diffraction.. While a large loudspeaker is naturally more directional because of its large size, a source with equivalent directivity can be made by utilizing an array of traditional small loudspeakers, all driven together in-phase.
Commercially, this type of loudspeaker arrangement is known as a line array. This technique has been around for many years but since the emergence of modern digital signal processing (DSP) technology there are now many commercially available products on the market. Beam steering and directivity Control using DSP was pioneered in the early 1990s ...
Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts.The electrical power delivered to the loudspeaker, together with its efficiency, determines the sound power generated (with the rest of the electrical power being converted to heat).
The DUBV 43C towed array sonar of La Motte-Picquet.. A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. [1] Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting ...
