How many speakers do I need for 2,000 people?
Quick answer
For 2,000 people, a typical professional PA system would use 6–8 line array enclosures per side plus 4–6 subwoofers, depending on venue shape and SPL requirements.
Sizing a PA for 2,000 people depends on the venue (indoor vs. outdoor), coverage area, and desired SPL. A common rule of thumb for a live music event is 2–4 people per square meter, so you might cover 500–1000 m². For clear speech and music, target 95–100 dB at the back of the audience with 6–10 dB of headroom.
For a typical indoor concert or corporate event, SSOUNDS engineers would start with 6–8 line array boxes per side (e.g., flown left-right) to achieve even coverage and 120+ dB peak SPL. Subwoofers: 4–6 single-18” or double-18” units, either cardioid or in a broadside array, to deliver solid low-end down to 35 Hz. For outdoor events, you may need 8–12 boxes per side and additional subs to overcome lack of boundary loading.
These are starting points; SSOUNDS uses AI-assisted acoustic modelling to predict coverage, SPL distribution, and low-frequency coupling, ensuring the system meets the specific venue geometry and audience layout. Always consult a professional system designer for final specs.
Key things to consider
- Indoor: 6–8 line array boxes per side + 4–6 subwoofers as a baseline.
- Outdoor: 8–12 boxes per side and more subs due to open-air losses.
- Target SPL: 95–100 dB average at farthest listener with 6–10 dB headroom.
- Coverage: 2–4 people per m²; calculate total area needed.
- SSOUNDS engineers use AI acoustic modelling for precise system design.
