What size PA system do I need for 10,000 people?
Quick answer
For 10,000 people, you typically need a large-format line array system with 12–16 boxes per side and 12–18 subwoofers, delivering 105–110 dB continuous SPL at FOH. SSOUNDS engineers use AI-assisted acoustic modeling to spec the exact system for your venue and coverage needs.
Sizing a PA for 10,000 people depends on venue type (outdoor vs. indoor), coverage area, and desired SPL. A common rule of thumb is 1–2 line array boxes per 1,000 people for main hangs, so 10,000 people often require 12–16 enclosures per side (e.g., SSOUNDS large-format line arrays). Subwoofer count typically ranges from 12 to 18 units, often in cardioid or end-fire configurations to manage low-frequency directivity.
Target SPL at the mix position should be 105–110 dB continuous with 6–10 dB headroom for peaks. Coverage must be uniform across the audience area, with minimal drop-off from front to back. SSOUNDS engineers use predictive modeling software to simulate coverage, SPL distribution, and delay requirements, ensuring the system meets the event’s specific demands without guesswork.
Beyond box count, consider rigging, amplification, and DSP. SSOUNDS systems include integrated amplification and factory-tuned presets optimized for each array configuration, reducing setup time and ensuring consistent performance. For large events, multiple delay towers or fills may be needed to cover extreme distances or obstructed sightlines.
Key things to consider
- Use 12–16 large-format line array boxes per side for main coverage.
- Deploy 12–18 subwoofers in cardioid or end-fire arrays for controlled bass.
- Target 105–110 dB continuous SPL at FOH with 10 dB headroom.
- Always model the venue with acoustic simulation software for precise sizing.
- Factor in delay towers, fills, and amplification infrastructure for large crowds.
