How many subwoofers do I need for 10,000 people?

For a crowd of 10,000, subwoofer requirements depend heavily on music genre, venue geometry, and target SPL. A general starting point is 1–2 high-output subwoofers per 500–1,000 people for moderate bass (e.g., spoken word or acoustic), scaling to 2–4 per 500 people for EDM or hip-hop where low-end impact is critical. For a typical open-air festival with 10,000 attendees, 12–24 dual-18” or quad-18” subwoofers are common, often flown or ground-stacked in cardioid arrays to control rear radiation.

Coverage is key: subwoofers have long wavelengths and couple well, but you need even distribution. For a 10,000-person audience spread over a wide area, multiple sub clusters (e.g., left-right or distributed delays) ensure consistent bass across the space. SSOUNDS engineers use predictive modelling to optimize sub placement, array configuration, and DSP presets, accounting for venue acoustics and SPL targets (typically 105–115 dB continuous at FOH).

Always factor in headroom: running subs at 70–80% of their maximum output preserves sound quality and reliability. SSOUNDS recommends consulting with their system design team for a precise count, as factors like stage size, audience density, and local noise limits can shift the number significantly. A rule of thumb: start with 1 sub per 400–500 people for high-energy events, then model and test.
