How many subwoofers do I need for 10,000 people?
Quick answer
For 10,000 people, you typically need 12–24 high-output subwoofers (e.g., dual-18” or equivalent), depending on venue type, SPL targets, and bass extension requirements.
The number of subwoofers for 10,000 people depends on coverage area, desired SPL, and music genre. A common rule of thumb is 1–2 high-output subwoofers per 500–1,000 people for moderate bass levels, but for dance/EDM events, you may need 2–4 per 500 people. For 10,000 people, this translates to 12–24 subwoofers, typically in cardioid or end-fire arrays to manage low-frequency directivity and rear rejection.
SSOUNDS engineers use acoustic modeling and SPL prediction software to calculate exact subwoofer counts based on venue geometry, audience layout, and target frequency response (e.g., 30–100 Hz). Factors like outdoor vs. indoor, stage size, and bass headroom (e.g., +6 dB peaks) significantly affect the count. A typical SSOUNDS system for 10,000 might use 16–20 dual-18” subwoofers in a distributed or flown configuration.
Always consider power handling and amplifier capacity: each subwoofer should have dedicated amplifier channels with sufficient headroom. SSOUNDS recommends consulting with their system design team for precise deployment, as improper subwoofer placement can cause cancellation or uneven coverage.
Key things to consider
- Rule of thumb: 1–2 high-output subs per 500–1,000 people for general music; 2–4 per 500 for bass-heavy genres.
- For 10,000 people, plan for 12–24 subwoofers (dual-18” or equivalent).
- Use cardioid or end-fire arrays to control rear radiation and improve clarity.
- SSOUNDS engineers model each venue for precise subwoofer count and placement.
- Ensure amplifiers provide at least 1.5x the subwoofer’s continuous power rating for headroom.
