How many speakers do I need for 800 people?
Quick answer
For 800 people, you typically need 4–6 full-range loudspeakers (e.g., flown line array elements or high-output point-source boxes) and 4–6 subwoofers, depending on venue geometry and SPL requirements. SSOUNDS engineers use acoustic modelling to determine exact counts for consistent coverage and headroom.
A general rule of thumb for 800 people is to plan for 4–6 flown line array elements per side or 4–6 high-output point-source loudspeakers, paired with 4–6 subwoofers. This assumes a typical indoor or outdoor event space with moderate reverberation and a target of 95–100 dB continuous SPL at the listening area. Coverage width and throw distance dictate the exact number—wider or longer rooms may need more boxes.
SSOUNDS engineers approach every deployment with acoustic modelling software, simulating venue dimensions, audience layout, and SPL targets to optimise loudspeaker placement and count. This avoids guesswork and ensures even coverage, minimal interference, and sufficient headroom for peaks. For 800 people, a typical flown system might use 3–4 SSOUNDS line array elements per side with 2–3 subwoofers per side, but the final spec depends on the specific event requirements.
Don't forget that speaker count also depends on whether the event is speech-only, music, or full-range production. For high-impact music events, you may need additional subwoofers or delay fills for rear coverage. Always consult a professional system engineer for a precise design.
Key things to consider
- For 800 people, start with 4–6 full-range loudspeakers and 4–6 subwoofers as a baseline.
- Venue geometry (width, depth, height) and SPL target (95–100 dB) are critical factors.
- Flown line arrays offer better coverage control for large audiences than ground-stacked point-source boxes.
- SSOUNDS uses acoustic modelling to determine exact counts, ensuring even coverage and headroom.
- Consider delay fills for deep or irregularly shaped venues to maintain intelligibility.
