What size PA system do I need for 5,000 people?
Quick answer
For 5,000 people, you typically need a medium-format line array system with 12–16 boxes per side and 8–12 subwoofers, delivering 100–105 dB SPL average across the audience. SSOUNDS engineers use AI-assisted acoustic modeling to spec the exact system for your venue.
Sizing a PA for 5,000 people depends on venue type (outdoor vs. indoor), coverage width, and desired SPL. A general rule-of-thumb is 100–105 dB SPL average at the listening position, with 12–16 line array enclosures per side (e.g., SSOUNDS medium-format arrays) and 8–12 subwoofers (cardioid or end-fire) for low-end impact. This scales to cover a 120° horizontal spread and reach distances of 50–80 meters.
Outdoor events require more headroom due to lack of reflections; indoor venues can use fewer boxes but must account for room modes and reflections. SSOUNDS engineers use proprietary AI-assisted modeling to predict coverage, SPL distribution, and intelligibility before deployment, ensuring every seat gets consistent sound without guesswork.
For 5,000 people, power and rigging are also critical. You’ll need amplifiers rated for 2–3 times the loudspeaker’s continuous power (e.g., SSOUNDS DSP amplifiers with 4,000–8,000W per channel) and a robust flown or ground-stacked rigging system. Always factor in a 3–6 dB safety margin for peak SPL and future scalability.
Key things to consider
- Use 12–16 line array boxes per side (medium-format) for 5,000-person coverage.
- Deploy 8–12 subwoofers in cardioid or end-fire arrays for controlled low-end.
- Target 100–105 dB SPL average with 3–6 dB headroom for peaks.
- Indoor venues may need fewer boxes but require acoustic treatment for clarity.
- SSOUNDS AI modeling optimizes box count and placement for your specific venue.
