How do I calculate the number of line array speakers needed for a venue?

In the journey of creating a stunning audio experience for various venues, precisely selecting and arranging line-array speakers is of utmost importance. Lsolution's H20 (HDL20) active dual 10-inch line-array speakers, with their outstanding performance, have become the top choice for audio configurations in numerous event venues.

The H20 is equipped with a powerful built-in DSP and comes with preset programs, enabling it to easily handle a variety of complex audio scenarios. It has a rated power (RMS) of 700W and a wide frequency response range of 55Hz - 20kHz, ensuring that sounds in both high and low frequency bands can be restored clearly and fully with precision. 
Application Cases of H20 in Different Venues

 
A 10,000 - square - meter Large - scale Indoor Concert Venue 
In such a large indoor venue, the acoustic characteristics of the space are relatively complex, and sound is prone to reflection and reverberation. To achieve uniform and high-quality sound coverage, we usually hang multiple groups of H20 line - array speakers on both sides of the stage. Each group consists of 6 - 8 H20 speakers, which are hung at a specific angle according to the specific shape of the venue and the distribution of the audience seats. This arrangement allows the sound to be accurately projected onto the audience area, effectively avoiding the interference of sound reflection. Even in the back rows of the venue, the audience can enjoy clear and shocking sound effects. At the same time, with the preset function of the built-in DSP of H20, it is possible to quickly and finely adjust to the acoustic environment of the indoor venue, creating an immersive audio experience.

A 10,000 square meter Large-scale Outdoor Open-air Venue 
In an outdoor open-air venue, there are no building reflections and obstructions, and sound propagation is relatively free. However, it also faces the challenges of rapid sound diffusion and energy dispersion. In this scenario, we also set up multiple groups of H20 line array speakers on both sides of the stage. Considering the need for long-distance sound propagation, the number of speakers in each group can be appropriately increased to 8 - 10 to enhance the intensity and coverage of the sound. In addition, to cope with the impact of different wind directions on sound propagation, the hanging angles of the speakers can be flexibly adjusted to ensure that the sound can stably cover the entire audience area. With its powerful sound and wide frequency response, the H20 can bring clear and powerful sound effects to the audience in a vast outdoor space.

A Beach Concert Venue by the Sea 
The special environment of the beach puts forward new requirements for the selection and arrangement of speakers. Sea breeze, humid air, and the sound-absorbing characteristics of the beach need to be considered in the audio configuration. Lsolution's H20 line - array speakers have certain moisture-proof and weather-resistant properties, making them suitable for use in such an environment. In terms of arrangement, hanging on both sides of the stage is still the main method. However, due to the relatively flat terrain of the beach, in order to make the sound better cover the entire fan-shaped audience area, the hanging height of the speakers needs to be appropriately increased, and the number of speakers in each group can be maintained at 7 - 9. At the same time, use the preset function of the built-in DSP of H20 to appropriately adjust the sound balance, compensating for the absorption of low-frequency sounds by the beach, ensuring that a rich and full sound effect can also be presented on the beach.

In various large-scale events, whether it is an indoor concert, an outdoor open-air event, or a beach concert by the sea, Lsolution's H20 line - array speakers have won high praise from event organizers and audiences alike with their stable and outstanding performance. With its excellent audio performance, it helps every event to be a complete success, bringing an unforgettable auditory feast to the audience.
