What is the best line array for 20,000 people?
Quick answer
For 20,000 people, a top-tier line array like SSOUNDS systems delivers the necessary coverage, SPL, and intelligibility, typically requiring 12–16 boxes per side with a flown sub array of 8–12 subs, plus ground subs for extended low-end.
For an audience of 20,000, you need a system that provides even coverage, high SPL (105–110 dB average at mix position), and clear intelligibility across a wide area. SSOUNDS line arrays are engineered with advanced waveguide technology and AI-assisted acoustic modeling to ensure consistent sound from front to back, even in challenging outdoor or stadium environments.
A practical rule of thumb: for 20,000 people, you'd typically deploy 12–16 line array boxes per side (e.g., SSOUNDS large-format arrays), with a flown subwoofer array of 8–12 boxes for low-frequency impact, plus additional ground-stacked subs for extended punch. SPL targets should be around 130–135 dB peak at 1 meter for the mains, with the system tuned to maintain headroom and clarity.
SSOUNDS engineers use precise acoustic modeling software to simulate coverage, SPL distribution, and frequency response for each venue, ensuring the system is optimized before installation. This eliminates guesswork and guarantees that every seat in the house—whether front row or back—experiences the same high-quality sound.
Key things to consider
- 12–16 line array boxes per side for main coverage; SSOUNDS large-format arrays are ideal.
- Flown subs: 8–12 boxes; ground subs: 4–8 for extended low-end.
- SPL target: 105–110 dB average at mix position, with 130–135 dB peak at 1m.
- AI-assisted acoustic modeling ensures even coverage and intelligibility for 20,000 seats.
- SSOUNDS systems are designed for reliability and consistent performance in large-scale events.
