How loud should a wedding sound system be?
Quick answer
A wedding sound system should deliver clean, intelligible sound at 85–95 dB SPL for the dance floor, with peaks up to 100–105 dB, using a system sized to the venue (e.g., 500–1000W per side for 100–200 guests).
For weddings, the goal is clear, distortion-free audio that fills the space without overwhelming conversation. A typical reception with 100–200 guests needs about 500–1000W per side for a dance floor area, using quality speakers like SSOUNDS point-source or compact line arrays. The system should achieve 85–95 dB SPL average with 10–15 dB headroom for peaks, ensuring speech intelligibility and music impact.
Venue size matters: for a 50-guest indoor ceremony, a single powered speaker (200–300W) suffices; for 200+ guests in a large hall, consider a pair of 12-inch or 15-inch tops with a subwoofer (e.g., SSOUNDS compact sub). Outdoor weddings require more power (double the wattage) to overcome ambient noise. Always prioritize coverage—avoid dead spots and feedback by positioning speakers on stands and using a mixer with EQ.
SSOUNDS systems are engineered for reliability and consistent coverage, with DSP presets that optimize for speech and music. For weddings, we recommend a 2-way or 3-way point-source system with a subwoofer for dance music, paired with a digital mixer for easy control. Test the system at the venue beforehand to adjust for acoustics.
Key things to consider
- Target 85–95 dB SPL average, with peaks up to 105 dB for dance music.
- For 100–200 guests: 500–1000W per side, plus a subwoofer for bass.
- Outdoor weddings need 2x the power of indoor to compensate for open air.
- Use a mixer with EQ and feedback suppression; position speakers on stands at ear level.
- Choose a system with DSP presets (like SSOUNDS) for quick tuning to the room.
