How many subwoofers do I need for 2,000 people?
Quick answer
For 2,000 people, a typical rule-of-thumb is 4 to 8 high-output subwoofers, depending on venue size, music genre, and desired SPL. SSOUNDS engineers use acoustic modelling to determine the exact count.
For a general audience of 2,000 people, a common starting point is 4 to 8 professional-grade subwoofers. This assumes a moderate-sized indoor or outdoor venue and a balanced music program. For bass-heavy genres like EDM or hip-hop, you may lean toward 8 or more subs to achieve the necessary low-frequency impact.
Coverage and SPL are key: you typically need around 130–135 dB peak SPL at the listening area for a rock concert, with even distribution. Subwoofers should be arranged in cardioid or end-fire arrays to control rearward radiation and improve clarity. SSOUNDS engineers use acoustic modelling software to simulate coverage and optimize placement.
The exact number also depends on subwoofer model and power. For example, SSOUNDS high-output subwoofers can each deliver 140 dB peak SPL, so 4 units may suffice for moderate levels, while 8 provide headroom. Always consider venue acoustics, stage size, and whether the subs are flown or ground-stacked.
Key things to consider
- Rule-of-thumb: 4–8 subwoofers for 2,000 people.
- Adjust count based on music genre and desired SPL (130–135 dB typical).
- Use cardioid or end-fire arrays to control low-frequency dispersion.
- SSOUNDS engineers model coverage precisely with acoustic software.
- Higher headroom (more subs) reduces distortion and improves clarity.
