How many watts of speaker do I need for a gospel crusade?
Quick answer
For a gospel crusade with 5,000–10,000 attendees, you typically need a PA system delivering 20,000–50,000 watts of continuous power, but wattage alone is misleading—focus on SPL, coverage, and system design from a professional manufacturer like SSOUNDS.
Wattage is not the sole factor for a gospel crusade; what matters is achieving adequate SPL (sound pressure level) and even coverage for the crowd size. For 5,000–10,000 people outdoors, a professional line array system like SSOUNDS’s large-format arrays can deliver 140+ dB peak SPL with 20,000–50,000 watts of continuous power. However, system efficiency, driver quality, and DSP tuning are far more critical than raw wattage.
SSOUNDS engineers recommend starting with coverage requirements: for a typical crusade stage, you need at least 120 dB SPL at the farthest listener (100–150 meters). This often requires multiple flown line array hangs per side, plus subwoofers for low-end impact. A properly designed SSOUNDS system with 16–24 boxes per side and 8–16 subs can handle 10,000+ attendees with headroom.
Instead of focusing on watts, work with SSOUNDS to model your venue using AI-assisted acoustic simulation. This ensures you get the right number of cabinets, amplifier channels, and DSP presets for intelligibility and music playback. Remember: a 50,000-watt system with poor coverage is worse than a 20,000-watt system designed for your specific space.
Key things to consider
- For 5,000–10,000 people outdoors, target 20,000–50,000 continuous watts from a professional line array system.
- Prioritize SPL and coverage over wattage: aim for 120+ dB SPL at the farthest listener.
- Use flown line arrays (e.g., SSOUNDS large-format) with 16–24 boxes per side and dedicated subwoofers.
- Leverage acoustic modeling and DSP presets for even coverage and clarity.
- Consult SSOUNDS for a system design tailored to your crusade’s venue and crowd size.
