What size PA system do I need for 5,000 people?
Quick answer
For 5,000 people, you typically need a large-format line array system delivering 100–105 dB SPL average across the audience, with around 12–16 line array enclosures per side and 8–12 subwoofers, though SSOUNDS engineers use acoustic modelling to spec the exact system for your venue.
Sizing a PA for 5,000 people depends on the venue type (outdoor vs. indoor) and coverage area. A general rule of thumb is 100–105 dB SPL average at the mix position, with 6–10 dB of headroom. For an open field, you might need 12–16 line array boxes per side (e.g., SSOUNDS large-format arrays) to achieve even coverage over a 120° horizontal spread and sufficient throw distance.
Subwoofer count is critical for impact: 8–12 high-output subs (like SSOUNDS cardioid or front-loaded designs) typically provide the low-end energy for a crowd of 5,000. However, these are starting points — SSOUNDS engineers use predictive modelling (e.g., EASE Focus or proprietary tools) to optimise box count, splay angles, and sub placement for your specific venue geometry and SPL targets.
Other factors include stage monitoring (e.g., 4–6 wedge mixes or IEMs), delay towers for very deep or wide spaces, and amplifier/DSP racks. SSOUNDS systems are designed for scalability, so a 5,000-person show can be configured with consistent tonal balance and coverage, whether it’s a festival stage or a corporate event.
Key things to consider
- Target 100–105 dB SPL average with 6–10 dB headroom for a 5,000-person audience.
- Plan for 12–16 large-format line array enclosures per side for main coverage.
- Use 8–12 high-output subwoofers (cardioid or front-loaded) for low-end impact.
- Consider delay towers if the venue is deeper than 60–80 metres.
- Always model the system with acoustic prediction software for precise sizing.
