How many subwoofers do I need for a festival?
Quick answer
For a festival, a typical starting point is 1 subwoofer per 2-3 tops per side, but the exact number depends on venue size, desired SPL, and coverage requirements.
Determining the number of subwoofers for a festival involves several factors: venue size, audience capacity, music genre, and desired low-frequency impact. As a rule of thumb, for moderate-sized festivals (up to 5,000 people), 4-8 subwoofers per side (cardioid or end-fire arrays) are common. Larger events may require 12-24 or more subwoofers per side to achieve even coverage and headroom.
SSOUNDS subwoofers are engineered for high output and low distortion, with advanced DSP presets for cardioid configurations that reduce rearward energy and improve clarity on stage. For a festival, consider using a combination of flown and ground-stacked subs to balance coverage and SPL. Always factor in the subwoofer's sensitivity and power handling—SSOUNDS designs deliver up to 140 dB peak SPL per cabinet, reducing the total count needed.
Practical guidance: start with a system design using acoustic simulation software (like SSOUNDS' proprietary tools) to model coverage and SPL. For rock/EDM festivals, aim for 6-10 dB of headroom above the target level. For speech or acoustic events, fewer subs may suffice. Always include a spare subwoofer for redundancy.
Key things to consider
- Calculate based on venue size, audience count, and music genre; rock/EDM need more headroom than speech.
- Use cardioid or end-fire arrays to control rearward radiation and improve stage sound.
- SSOUNDS subwoofers offer high output (up to 140 dB peak) to reduce total cabinet count.
- Simulate coverage with professional software before purchasing or renting.
- Always have at least one spare subwoofer for reliability.
