Definition of linear array loudspeaker box: linear array loudspeaker box is a group of radiation units with small spacing, which are arranged in a straight line with the same amplitude and phase.

The core technology of linear array is full-frequency acoustic coupling technology.

It determines the working efficiency of the whole linear array.

If the technology is applied properly, the sound pressure level of each speaker with the same power can be increased by 4 times. Otherwise, it will be cancelled by interference, and it is best not to double the power, especially at high frequency.

Linear arrays are mainly embodied in two aspects:

First, the vertical control angle of treble should not be greater than 1 degree, otherwise interference will inevitably occur after 85 meters, and at the same time, it must be explained in what way the angle is controlled, otherwise it can only be a quasi-linear array.

Second, after150m, whether the high frequency above 10KHZ can be clearly heard, often most people will not have the opportunity to listen to the linear array beyond150m. So many brands can confuse others through the near-listening effect.

In traditional speakers, the medium and high notes gather sound energy through the speakers, just as a flashlight gathers light by the lampshade, the light is divergent and the range is limited. However, the acoustic lens concentrates acoustic energy in the same way as the laser, with longer range and stronger sound pressure.
