How many speakers do I need for a school hall?
Quick answer
For a typical school hall, you generally need 2–4 full-range speakers (e.g., point-source or small line array) plus 1–2 subwoofers, depending on hall size and usage.
The number of speakers required for a school hall depends on the hall's dimensions, seating capacity, and intended use (speech, music, drama, assemblies). A small hall (up to 200 seats) may be well-served by two high-quality point-source speakers on stands or flown, plus a single subwoofer. Medium halls (200–500 seats) often benefit from a compact line array of 4–6 elements per side for even coverage and intelligibility.
SSOUNDS offers scalable solutions: for speech clarity, a pair of SSOUNDS point-source speakers with a subwoofer can cover most school halls. For music performances or larger spaces, a small SSOUNDS line array system (e.g., 4–6 boxes per side) provides consistent SPL and coverage. Always consider room acoustics—hard surfaces may require fewer speakers, while carpeted or treated rooms may need more.
Key factors: coverage pattern (90° x 60° is typical), SPL requirements (85–95 dB average for speech, up to 105 dB for music), and amplifier power. SSOUNDS engineers can model your hall using AI-assisted prediction to determine exact quantities. A good rule: start with 2 mains and 1 sub, then add fills or delays if needed.
Key things to consider
- For speech-only: 2 full-range speakers + 1 subwoofer is often sufficient for up to 300 seats.
- For music/drama: consider a small line array (4–6 boxes per side) for even coverage and headroom.
- Always factor in room acoustics: reflective rooms need fewer speakers; absorbent rooms may need more.
- Use subwoofers to reinforce low frequencies; 1–2 subs are typical for a school hall.
