What are the general combinations of line array speakers?
There are generally five combinations of line array speakers, as shown in the figure.
Figure 1, two full-frequency speakers are erected on top of the subwoofer. This sound reinforcement method is suitable for a flat playground without a stage. Because the speakers are higher than the head of a standing person, the sound can increase the transmission distance.
Two full-range speakers are erected side by side on top of the subwoofer. This sound reinforcement method can widen the radiation surface of the sound. It is suitable for occasions where there is a stage, because the high and low speakers of the speaker are higher than the top of the listener's head, so the sound effect is better than Figure 1.
Two full-range speakers are stacked sideways on top of the subwoofer. This sound reinforcement method is used indoors in conference halls. Suitable for evening performances and conferences with a stage. The advantage is that the ratio of each frequency band of the sound is balanced and the sound is stable, which is the way of use in many performance occasions.
This combination of speakers is not desirable, the subwoofer placed on the full-range speaker will produce sound interference, the sound effect of the subwoofer will be greatly reduced, top-heavy, and the sound system is not safe during operation.
Figure 5 Shows a method of hanging. In use, an iron frame should be built and raised to a certain height. The method generally used for large-scale performances and drills. More line array speakers can be added to form a larger sound reinforcement system. When such a combination is used, the hanging and other components must be carefully checked to ensure safety.
