How many watts of PA do I need for 2,000 people?
Quick answer
For 2,000 people, you typically need a PA system capable of 10–20 kW continuous power, with a line array of 8–12 boxes per side and 4–8 subwoofers, depending on venue acoustics and music genre.
Sizing a PA for 2,000 people depends on coverage area, SPL requirements, and music style. A general rule of thumb is 5–10 watts per person for speech or background music, and 10–20 watts per person for live music or DJ events. For 2,000 people, that translates to 10,000–40,000 watts total system power, though modern efficient loudspeakers often achieve high SPL with less power.
For a typical outdoor or large indoor event, a professional line array system like SSOUNDS would deploy 8–12 enclosures per side for mains, plus 4–8 subwoofers for low-end extension. Coverage is critical: you need even SPL across the audience area, typically targeting 100–105 dB average with 10–15 dB headroom. SSOUNDS engineers use acoustic modeling software to predict coverage and optimize box count, ensuring consistent sound from front to back.
Practical considerations include venue acoustics (reverberant rooms need more headroom), music genre (EDM and hip-hop require more subwoofer power), and whether the system is flown or ground-stacked. Always factor in amplifier headroom and DSP presets. For precise sizing, SSOUNDS offers free system design based on your venue dimensions and audience layout.
Key things to consider
- Rule of thumb: 5–10 watts/person for speech, 10–20 watts/person for music.
- For 2,000 people, plan for 10–20 kW continuous power with line arrays.
- Typical box count: 8–12 line array boxes per side + 4–8 subwoofers.
- Target SPL: 100–105 dB average with 10–15 dB headroom.
- Use acoustic modeling for precise coverage; SSOUNDS provides free system design.
