How many subwoofers do I need for 10,000 people?
Quick answer
For 10,000 people, a professional system typically uses 12–24 subwoofers, depending on venue type, SPL targets, and coverage requirements.
The number of subwoofers needed for 10,000 people depends on several factors: venue type (outdoor vs. indoor), desired low-frequency impact, and coverage pattern. As a rule of thumb, outdoor events require more subwoofers than indoor due to lack of boundary loading. For a rock concert targeting 105–110 dB SPL at the mix position, expect 16–24 subwoofers in a cardioid or end-fire array. For speech or moderate music, 12–16 may suffice.
SSOUNDS engineers use acoustic modelling software to predict coverage and SPL distribution. We consider the venue's geometry, audience area, and subwoofer directivity. For example, an outdoor festival with 10,000 people spread over a large area might need 24 subwoofers in a distributed or flown array, while a compact indoor arena could achieve results with 12–16 units.
Subwoofer count also depends on the system's headroom and the genre. Electronic dance music demands more low-end energy, often requiring 20–24 subwoofers. For spoken word or acoustic performances, 8–12 may be adequate. Always consult with a professional system designer to optimize for your specific event.
Key things to consider
- Outdoor events typically need more subwoofers (16–24) than indoor (12–16) for 10,000 people.
- Target SPL: 105–110 dB for rock concerts; lower for speech or acoustic.
- Subwoofer array type (cardioid, end-fire, distributed) affects count and placement.
- Genre matters: EDM needs more subwoofers than spoken word.
- Professional acoustic modelling is essential for precise results.
