Line Array Series consists of LA–208 compact full range system, LA–315 full size full range system, LA–215B dual 15–inch subwoofer, LA–218B dual 18–inch subwoofer and LA–121B single 21–inch subwoofer, any full range systems can be configured with any subwoofers to form a four-way system.
A line array is theoretically a continuum of small line segments distributed along a line. As compared to conventional loudspeaker array, the advantages of a line array are:
In near and mid field, the attenuation of sound pressure level due to increase of distance is smaller. (See Figure 4 and Figure 5) as the wavefront produced is planar rather than spherical. Within a certain distance, the sound pressure is more evenly distributed. It is not too loud close to the source and is not too weak at mid field.
The rated horizontal dispersion angle of the element (loudspeaker) is very wide and the vertical dispersion angle is very narrow. This superb control of directivity make it easier to concentrate the sound energy within the audience area and reduce the interference of reverbration field.
