How many watts of speaker do I need for a conference?
Quick answer
For a conference, you typically need 500–2000 watts total (RMS) for rooms up to 200 people, but wattage alone isn't the key factor—coverage, clarity, and system design matter more.
Wattage is often misunderstood in PA selection. For a conference, speech intelligibility and even coverage are far more important than raw power. A well-designed system with 500–1000 watts RMS can easily cover a room of 100–200 people if the speakers are positioned correctly and have good dispersion. For larger rooms or higher ambient noise, 1500–2000 watts RMS may be needed.
SSOUNDS recommends focusing on speaker type and configuration rather than just wattage. A pair of high-quality, 8-inch or 10-inch two-way speakers (e.g., SSOUNDS point-source systems) with 300–500 watts RMS each can handle most mid-sized conference rooms. For larger halls, a small line array or distributed system with multiple speakers ensures consistent volume and clarity from front to back.
Always consider amplifier headroom: choose an amplifier that provides 1.5–2 times the speaker's continuous power rating to avoid clipping. Also, use a DSP for EQ and limiting to protect speakers and maintain clear speech. SSOUNDS systems include integrated DSP presets optimized for speech, making setup straightforward.
Key things to consider
- For up to 100 people: 300–500 watts RMS total (e.g., two 150–250W speakers).
- For 100–200 people: 500–1000 watts RMS total with good coverage.
- For 200+ people or high noise: 1000–2000 watts RMS, possibly with subwoofers for fullness.
- Prioritize speaker dispersion (90° x 60° or wider) and speech-optimized DSP.
- Always use an amplifier with at least 1.5x the speaker's RMS rating for clean headroom.
