What size PA system do I need for 2,000 people?
Quick answer
For 2,000 people, you typically need a medium-format PA system capable of 100–105 dB continuous SPL at the listening area, with 4–6 line array enclosures per side and 4–8 subwoofers, depending on venue acoustics and music genre.
Sizing a PA for 2,000 people depends on coverage area and SPL requirements. As a rule of thumb, aim for 100–105 dB continuous SPL at the farthest listener, with 6–10 dB headroom. For a typical indoor venue (e.g., 30m deep, 40m wide), a medium-format line array like SSOUNDS’ systems with 4–6 boxes per side can deliver even coverage and intelligibility. Outdoors or for high-energy music, you may need 8–12 boxes per side and additional subwoofers.
Subwoofer count is driven by bass impact: 4–8 single-18” or double-18” subs per side are common for 2,000 people, with cardioid configurations to control rear spill. SSOUNDS engineers use acoustic modeling software to predict coverage, SPL distribution, and low-frequency response, ensuring the system meets the specific venue and event type—whether speech, acoustic music, or rock concerts.
Always consider factors like ceiling height, audience layout, and ambient noise. A distributed system (multiple smaller speakers) may be better for wide, shallow spaces, while a line array suits deep, narrow venues. SSOUNDS provides free system design support to calculate exact box counts and rigging for your event.
Key things to consider
- Target 100–105 dB continuous SPL at the listening area with 6–10 dB headroom.
- For indoor venues: 4–6 line array boxes per side; outdoor/high-energy: 8–12 per side.
- Subwoofers: 4–8 single-18” or double-18” per side, cardioid for directional control.
- Use acoustic modeling for precise coverage and SPL prediction—SSOUNDS offers this service.
- Adjust for venue acoustics, audience density, and music genre (speech vs. rock).
