What size PA system do I need for 10,000 people?

Sizing a PA for 10,000 people depends on coverage area, SPL requirements, and music style. A general rule of thumb: aim for 100–105 dB SPL average at the listening position with 10–15 dB headroom. For a typical outdoor festival or large arena, this means deploying a large-format line array—often 16 to 24 boxes per side—flown to cover the full audience depth. Subwoofer count ranges from 16 to 24 units, often in cardioid or end-fire configurations to control low-frequency directivity.

Venue shape matters: a wide, shallow space may need more hangs or delays, while a deep, narrow venue can use fewer boxes with higher throw. SSOUNDS engineers use AI-assisted acoustic modeling to predict coverage and SPL distribution before any gear is deployed, ensuring even coverage and intelligibility across the entire audience. For 10,000 people, we typically recommend our large-format line array systems, which deliver the headroom and pattern control needed for both speech and high-energy music.

Don't forget subwoofer placement and delay towers for very large or irregular spaces. A distributed subwoofer approach (e.g., multiple clusters) can improve low-frequency consistency. Always factor in local noise limits and rigging safety. SSOUNDS provides full system design support, including simulation files and on-site tuning, to guarantee your PA meets the event's demands.
