What size PA system do I need for 2,000 people?
Quick answer
For 2,000 people, you typically need a medium-format line array system capable of 105–110 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, SPL requirements, and content type. A general rule of thumb: for speech or light music, aim for 100–105 dB continuous at the mix position; for rock or EDM, 110–115 dB. Coverage should extend evenly across the audience, typically requiring a line array with 4–6 boxes per side for a 30–40m throw, plus 4–8 subwoofers for low-end impact.
SSOUNDS engineers use AI-assisted acoustic modeling to calculate exact box counts, splay angles, and subwoofer placement for each venue. For a 2,000-capacity indoor space, a typical SSOUNDS system might include 6 x L-Series line array per side, 4 x S-Series subwoofers flown or ground-stacked, and 2–4 front-fills for nearfield coverage. This ensures consistent SPL and intelligibility without over-specifying.
Outdoor events require more headroom: add 3–6 dB to SPL targets and increase subwoofer count by 50%. Always factor in amplifier power and DSP presets—SSOUNDS systems include machine-learning-tuned presets that optimize performance for the specific rigging configuration.

Key things to consider
- Target SPL: 105–110 dB continuous for music, 100 dB for speech at the listening area.
- Line array: 4–6 boxes per side for a 30–40m throw; more for outdoor or high-SPL events.
- Subwoofers: 4–8 units, cardioid or end-fire arrays to control low-frequency coverage.
- Use acoustic modeling software (e.g., SSOUNDS’ AI tools) to optimize box count and splay angles.
- Always include 3–6 dB of headroom for peaks and environmental factors.
