How loud should a sound system be for 200 people?

The key metric is achieving even coverage at ear level across the audience area. For 200 people in a typical room (e.g., 20m x 15m), aim for 95–100 dB SPL continuous program level with 6–10 dB of headroom for peaks. This ensures clarity for speech and punch for music without distortion.

A practical rule-of-thumb: use 2–4 high-output point-source or compact line array boxes per side, each capable of 125–130 dB SPL peak. For subwoofers, 1–2 units (e.g., dual 18-inch) provide sufficient low-end for music; for speech-only, subs may be optional. SSOUNDS engineers always verify with acoustic modelling to account for room acoustics and coverage patterns.

Coverage angle is critical: 90° x 60° horns or adjustable line array elements ensure the front rows aren't blasted while rear rows get adequate level. For 200 people, a single stereo pair of 12-inch or 15-inch two-way speakers on stands often suffices, but flown arrays or distributed delays may be needed for wide or deep rooms.

Headroom is non-negotiable: a system running at its limit sounds harsh and risks damage. SSOUNDS designs systems with ample amplifier power and DSP limiting to protect drivers while maintaining clean output. Always spec for the loudest expected content, not just average speech levels.
