Actual sound reinforcement occasions include many large halls, venues, outdoor open-air stages, etc., and the live environment and audience positions are different. This needs to be applied to the acoustic characteristics of Line Array​s of different shapes. Including straight line sound sources, arc sound sources, J-type sound sources, progressive sound sources, etc.

The line array​ speaker system has been widely developed and applied at home and abroad in recent years, and it appears in large-scale sports games and large-scale performances with its unique advantages. It can almost be said that no speaker manufacturing company does not produce line array speakers.

The development basis of the line array speaker system is the development of theoretical research and the progress of manufacturing technology. The requirements for the sound reinforcement function and the promotion of the market are the driving force for the development of line array speakers.

The sound reinforcement system is a system that amplifies the voice of the performer in real-time and transmits it to the listener. Performers and listeners are usually in the same acoustic environment. Line Array must meet the needs of users during the design process, and design the sound structure so that it can cover the entire venue step by step and clearly.
