 THE SERIES

 

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:

1.

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.

2.

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.

PHASE SERIES

 THE SERIES

Phase Series consists of PH-108, PH-110, PH-112 and PH-115 full range speakers plus PH-118B subwoofer, altogether 5 models. The goals of applications of this series are:

  • A sound reinforcement system needs only two full range speakers plus two subwoofers for smaller activities or even only two full range speakers would be suffice for some occasionsThe entire sound reinforcement system requires minimum number of power amplifiersOther than used as the main speakers of a small sound reinforcement system it may also be used as the auxiliary or supplement speaker for large systems such as stage front fill, delay fill and near field fill, etc. Since only small amount of speakers to make up a system, each individual speaker must have sufficient bandwidth, smooth phase and frequency response. All speaker units were designed and developed toward this goal
  • Good performance to price ratio
