What size PA system do I need for 200 people?
Quick answer
For 200 people, a medium-format PA system with 2–4 loudspeakers and 2 subwoofers typically suffices, delivering 90–100 dB SPL with clear coverage. SSOUNDS engineers use acoustic modelling to spec the exact system for your venue.
A 200-person audience is a common mid-size event (e.g., corporate, wedding, small concert). Rule of thumb: you need a system capable of 90–100 dB SPL at the listening area with even coverage. For indoor venues, 2–4 full-range loudspeakers (e.g., SSOUNDS point-source or compact line array) plus 2 subwoofers for low-end punch are typical. Outdoors, add more subs and increase SPL headroom by 3–6 dB.
Coverage is key: aim for 90°–120° horizontal dispersion per box, with vertical coverage tailored to room height. SSOUNDS engineers use predictive software (e.g., EASE, Soundvision) to model coverage, SPL distribution, and intelligibility, ensuring no dead spots or feedback zones. For 200 people, a single flown line array of 4–6 elements per side or a pair of high-output point-source boxes often works.
Subwoofer count depends on bass demand: for speech, 1–2 subs; for music, 2–4 subs in cardioid or end-fire arrays to control low-frequency buildup. Amplification must match loudspeaker RMS ratings—SSOUNDS DSP amplifiers provide 2–4 kW per channel with system tuning presets. Always factor in venue acoustics (reverberation, absorption) and local noise limits.
Key things to consider
- Target SPL: 90–100 dB at listening area; add 6 dB headroom for peaks.
- Loudspeaker count: 2–4 full-range boxes (point-source or compact line array).
- Subwoofers: 2–4 units, depending on music vs. speech content.
- Coverage: 90°–120° horizontal; vertical coverage matched to room height.
- SSOUNDS engineers use acoustic modelling to optimize system design for any venue.
