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 capable of 100-105 dB continuous SPL at the listening area, with at least 12-16 enclosures per side and 8-12 subwoofers, though SSOUNDS engineers use acoustic modelling to spec exactly for your venue.
Sizing a PA for 5,000 people depends on venue type (outdoor vs. indoor), coverage area, and content. A general rule of thumb: aim for 100-105 dB average SPL at the furthest listener, with 6-10 dB headroom. For a typical outdoor festival stage, this often means 12-16 large-format line array enclosures per side (e.g., SSOUNDS flagship arrays) and 8-12 high-output subwoofers in cardioid or end-fire configurations.
Coverage is critical: a single line array cluster per side can cover 120° horizontal and 90° vertical with proper splay angles. For deeper venues, add delay towers. SSOUNDS systems are designed for consistent coverage across the audience plane, minimizing off-axis coloration. Always factor in crowd absorption and ambient noise (e.g., 85 dB for a loud crowd).
SSOUNDS engineers use proprietary acoustic modelling software to simulate coverage, SPL distribution, and phase coherence before deployment. This ensures you get the exact number of boxes and subs for your specific venue, avoiding over- or under-specification. For a 5,000-person event, we typically recommend a flown main array, ground-stacked subs, and front-fills for the first rows.
Key things to consider
- Target 100-105 dB average SPL at listening area with 6-10 dB headroom.
- Typical rig: 12-16 large-format line array enclosures per side + 8-12 subwoofers.
- Coverage depends on venue shape; use delay towers for deep spaces.
- SSOUNDS uses acoustic modelling for precise, venue-specific sizing.
- Always account for crowd noise and ambient conditions.
