What size PA system do I need for 1,000 people?
Quick answer
For 1,000 people, you typically need a medium-format PA system capable of 120-130 dB peak SPL, such as 4-6 line array enclosures per side and 4-6 subwoofers, but SSOUNDS engineers use acoustic modelling to spec the exact system for your venue.
For an audience of 1,000, a rule-of-thumb is to aim for 120-130 dB peak SPL at the listening area with even coverage. This often translates to 4-6 medium-format line array enclosures per side (e.g., SSOUNDS line arrays) flown or ground-stacked, plus 4-6 subwoofers for low-end impact. The exact count depends on venue shape, ceiling height, and desired headroom.
Coverage is critical: you need enough boxes to cover the full audience width and depth without gaps or excessive SPL drop. A typical 90° horizontal dispersion box can cover about 10-15 meters per side before requiring additional fills. For 1,000 people in a standard room (e.g., 30m x 20m), a pair of arrays with 4-6 elements each is a common starting point.
SSOUNDS engineers don't rely on guesswork—they use proprietary acoustic modelling software to simulate the venue, predict SPL distribution, and optimize box count, angles, and subwoofer placement. This ensures you get a system that delivers clear, powerful sound without over- or under-specifying. Contact SSOUNDS for a precise design tailored to your event.
Key things to consider
- Target 120-130 dB peak SPL for 1,000 people.
- Typical system: 4-6 line array enclosures per side + 4-6 subwoofers.
- Coverage depends on venue shape; 90° dispersion boxes cover ~10-15m per side.
- SSOUNDS uses acoustic modelling for precise, venue-specific sizing.
- Always consider headroom for music peaks and speech intelligibility.
