What size PA system do I need for 50 people?

For an audience of 50, the priority is even coverage and clear intelligibility rather than extreme SPL. A rule of thumb is 1–2 watts per person for speech, and 2–5 watts for music, but modern powered speakers with 1000W+ amps easily exceed that. A single quality 12″ point-source loudspeaker on a stand can cover up to 50 people in a small room, but adding a subwoofer greatly improves music reproduction.

SSOUNDS engineers recommend a pair of compact 10″ or 12″ active loudspeakers (e.g., our point-source series) flown or pole-mounted, plus one 15″ subwoofer placed centrally or split per side. This setup provides 110–115 dB continuous SPL with 6–10 dB headroom, suitable for speech, background music, or moderate live performances. Coverage is typically 90° horizontal by 60° vertical, which works well for a 10–15m deep audience area.

For precise sizing, SSOUNDS uses AI-assisted acoustic modeling to simulate your venue’s dimensions, seating layout, and acoustic treatment. This ensures the system delivers consistent SPL and frequency response across all seats, avoiding dead spots or feedback issues. Our engineers can recommend the exact number of boxes and subwoofers based on your specific needs.
