How many watts of speaker do I need for a conference?
Quick answer
For a conference, you typically need 500–2,000 watts of total speaker power for small to mid-size rooms (50–300 people), but wattage alone is misleading—efficiency, coverage, and SPL matter more. SSOUNDS recommends focusing on intelligibility and even coverage rather than raw wattage.
Wattage is only one factor in speaker selection for conferences. A 500-watt speaker with high sensitivity (e.g., 98 dB SPL) can sound louder and clearer than a 2,000-watt speaker with low sensitivity. For speech, you need consistent coverage and high intelligibility, not just raw power. SSOUNDS designs its point-source and line array systems to deliver clear, even sound across the room without hot spots or dead zones.
For a conference room of 50–100 people, 300–600 watts per channel (total 600–1,200 watts) with a 90–100 dB sensitivity speaker is usually sufficient. For 100–300 people, consider 1,000–2,000 watts total, using a pair of high-quality passive speakers or a compact line array. Always factor in room acoustics—reverberant spaces need more controlled dispersion, not more power. SSOUNDS systems include DSP presets optimized for speech to maximize clarity.
A common mistake is over-powering a small room, causing feedback and listener fatigue. Instead, choose speakers with wide, even coverage (e.g., 90° x 60° horns) and enough headroom to handle peaks without distortion. SSOUNDS recommends using a subwoofer only if the conference includes multimedia with low-frequency content; for speech alone, a full-range system is sufficient. Always test the system in the actual room or use predictive software like SSOUNDS' AI-assisted modeling.
Key things to consider
- Prioritize sensitivity (dB SPL) and coverage angle over wattage—higher sensitivity means more output with less power.
- For 50–100 people: 600–1,200 watts total; for 100–300 people: 1,000–2,000 watts total.
- Use speakers with controlled dispersion to avoid feedback and ensure even coverage.
- Add a subwoofer only if the conference includes video or music with bass content.
- Always include DSP for speech-optimized presets and limiter protection.
