What size PA system do I need for 500 people?

For 500 people, you generally need a medium-format PA system capable of 120–125 dB peak SPL at the listening area. Coverage depends on the venue shape: a 90° horizontal dispersion line array or point-source cluster works for most rooms, with 2–4 tops per side and 2–4 subwoofers (e.g., dual-18” or cardioid arrays) for balanced low-end. SSOUNDS engineers use AI-assisted acoustic modeling to predict coverage, SPL distribution, and subwoofer coupling, ensuring every seat gets clear, powerful sound.

A practical rule of thumb: for a typical indoor space (e.g., 30m x 20m), a system with 2–3 line array enclosures per side plus 2–4 subwoofers will cover 500 people with headroom. Outdoors, you may need 4–6 enclosures per side and more subs to overcome ambient noise. SSOUNDS designs systems that scale predictably, so you can start with a core rig and expand as needed.

Don’t forget processing and amplification: SSOUNDS DSP presets optimize system performance for each configuration, and our amplifiers deliver clean power with built-in protection. For 500 people, a total system power of 4,000–8,000 watts (continuous) is typical, but the exact spec depends on your SPL target and music genre.
