How many speakers do I need for 10,000 people?
Quick answer
For 10,000 people, a professional system typically uses 12–24 line array enclosures per side plus 12–24 subwoofers, depending on venue shape and SPL requirements.
Covering 10,000 people requires a system capable of delivering at least 100–105 dB SPL average across the audience with 6–10 dB of headroom. A typical rule of thumb is 2–4 line array boxes per 1,000 people for the main hangs, so for 10,000 you'd need 20–40 boxes total (e.g., 10–20 per side). Subwoofer count is often 1 sub per 2–4 line array boxes, so 10–20 subs. These numbers vary with venue shape, desired low-end impact, and whether it's indoor or outdoor.
For outdoor events, you need more output to overcome ambient noise and lack of reflections. A single SSOUNDS line array box can cover about 30–40 meters with consistent SPL, so a 10-box-per-side hang can reach 10,000 people in a typical field. Indoor venues may require fewer boxes due to reflections, but careful aiming is needed to avoid feedback and dead spots.
SSOUNDS engineers use acoustic modelling software (e.g., EASE, Soundvision) to precisely calculate coverage, SPL distribution, and subwoofer placement. They consider factors like audience area, seating rake, and frequency response to ensure even coverage and intelligibility. For 10,000 people, a typical design might use 12–16 line array boxes per side and 12–24 subwoofers in cardioid or end-fire arrays.
Key things to consider
- Rule of thumb: 2–4 line array boxes per 1,000 people; for 10,000, that's 20–40 boxes total.
- Subwoofer count: 1 sub per 2–4 line array boxes; 10–20 subs typical.
- Outdoor events need more boxes than indoor due to lack of reflections.
- SPL target: 100–105 dB average with 6–10 dB headroom.
- SSOUNDS uses acoustic modelling for precise system design.
