The loudspeaker has excellent directivity and powerful power output, and can easily cope with large indoor environments with long reverberation time, such as airport waiting room, railway station and meeting place. In addition, it can also be used for outdoor applications, such as railway stations or gyms. It has a complete frequency range, making it ideal for speech and music playback. System overview LBC 3210/00 is designed to be installed in a way that saves time and effort. The speaker is accompanied by a diagram showing the cover area of the speaker and the corresponding ideal mounting height. After determining the corresponding height of a specific area, the speaker can be installed at the Angle indicated on the mounting bracket. This process is simpler and more accurate than the traditional installation method of trial assembly and rectification. L32bc 10/00 can be mounted on the wall or mounted directly on the LBC 1259/01 landing bracket using M10 threaded bolts without any other accessories. The mounting bracket attached to the loudspeaker is marked with mounting Angle.

The advanced filtering and positioning function of loudspeaker actuator has improved the audio directivity of loudspeaker significantly. Each speaker actuator generates a specific frequency range. Compared with the traditional pillar loudspeaker, the linear array loudspeaker has the following significant advantages. The sound is evenly distributed throughout the listening area: the area near the speaker is not too loud, and the area far away from the speaker is not too low. All related frequencies are located in any corner of the listening area. This allows for greater coverage so that more listeners can hear the voice and music clearly. All of these important features provide an extremely natural and high-quality hearing experience for listeners in the listening area. Easy to install, simple and advanced filtering capabilities enable high frequencies to generate larger vertical open angles, thereby reducing the high tone "narrow beam." Compared with the traditional sound column, the line array loudspeaker has a more constant opening Angle to the related frequencies. In 4 kHz, for example, the vertical opening Angle is still 18 °. A more stable vertical opening Angle makes installation easier because the wide coverage area of the speaker reduces the importance of positioning the speaker. 4 kHz frequency level open Angle is 90 °, which means that a single speaker only can in the vast listen to the voice of the area to provide natural effect.
