How many subwoofers do I need for a festival?
Quick answer
For a festival, the number of subwoofers depends on venue size, desired SPL, and coverage—typically 4 to 8 per main stage for medium events, scaling up for larger crowds.
Subwoofer quantity is determined by the area and audience capacity. For a small festival (up to 5,000 people), 4 to 6 high-output subwoofers per side may suffice. For medium festivals (5,000–20,000), 8 to 12 per side are common. Large festivals (20,000+) often require 16 or more per side, often in cardioid arrays to control low-frequency spill.
SSOUNDS subwoofers are engineered for high SPL and low distortion, allowing fewer cabinets to achieve desired output. Consider using a combination of front-loaded and cardioid subwoofers to maximize efficiency and reduce rearward energy. Always account for factors like stage size, bass-heavy music genres, and local noise restrictions.
A practical approach: calculate required SPL at the furthest listening point, then model coverage with subwoofer array design software. SSOUNDS provides system design support to optimize sub count and placement for your specific festival layout.
Key things to consider
- Small festival (up to 5,000): 4–6 subwoofers per side
- Medium festival (5,000–20,000): 8–12 per side
- Large festival (20,000+): 16+ per side, often cardioid arrays
- Use high-output subs to reduce cabinet count; SSOUNDS subs deliver high SPL per box
- Always model coverage and SPL with design software for accuracy
