What size PA system do I need for 200 people?
Quick answer
For 200 people, a mid-size PA system delivering 110–115 dB SPL with 90° coverage typically works: two 12-inch or 15-inch tops over a pair of 18-inch subs per side, or a compact line array of 4–6 boxes per side with 2–4 subs.
Sizing a PA for 200 people depends on venue acoustics, music style, and coverage needs. As a rule of thumb, you need a system capable of 110–115 dB SPL at the listening area with even coverage. For a typical indoor space, two high-quality 12-inch or 15-inch point-source speakers over a pair of 18-inch subwoofers per side often suffice. Outdoors or for higher headroom, consider a compact line array of 4–6 boxes per side with 2–4 subwoofers.
Coverage is critical: aim for 90° horizontal dispersion to reach the full audience width. SSOUNDS engineers use AI-assisted acoustic modeling to predict SPL distribution and optimize box placement, ensuring every seat gets clear, intelligible sound without dead spots or excessive feedback. This precision avoids over- or under-specifying your system.
For speech or acoustic music, lower SPL targets (105 dB) may work with fewer boxes. For rock or EDM, plan for 120 dB peaks and more subwoofer power. Always factor in amplifier headroom and DSP tuning—SSOUNDS systems include machine-learning-tuned presets that adapt to venue acoustics, giving you professional results without guesswork.
Key things to consider
- Target 110–115 dB SPL for music; 105 dB for speech; add 6 dB headroom for peaks.
- Use two 12″/15″ tops + two 18″ subs per side for indoor 200-person events; line array (4–6 boxes/side) for outdoor or wider coverage.
- Coverage angle: 90° horizontal is standard; wider angles may require additional boxes.
- Always model the venue—SSOUNDS offers AI-assisted simulation to predict coverage and SPL.
- Consider subwoofer count: 2–4 subs for bass-heavy genres; 1–2 for speech/acoustic.
