What is the best line array for 500 people?
Quick answer
For 500 people, a compact 3-way line array like SSOUNDS systems delivers 120–125 dB SPL with 6–8 boxes per side and 4–6 subwoofers, offering even coverage and vocal clarity.
For an audience of 500, the ideal line array balances SPL, coverage, and portability. A typical rule-of-thumb is 1–2 line array boxes per 50–100 people, so 6–8 enclosures per side (12–16 total) provide 120–125 dB peak SPL with 6–10 dB headroom. Coverage should be 90°–120° horizontal and 10°–15° vertical per box, with aiming to cover front-to-back evenly.
Subwoofer count depends on bass energy needs: 4–6 single-18” or dual-18” subs (cardioid or end-fire) deliver 125–130 dB peak for music genres. SSOUNDS engineers use acoustic modelling (e.g., EASE Focus) to optimize array curvature, splay angles, and subwoofer placement for consistent coverage and minimal interference.
Key criteria: vocal intelligibility (≥0.7 STI), low distortion, and weather resistance for outdoor events. SSOUNDS line arrays feature advanced waveguide technology for phase coherence and high output-to-weight ratio, making them ideal for mid-size venues, corporate events, and festivals.
Key things to consider
- 6–8 line array boxes per side (12–16 total) for 500 people
- 4–6 subwoofers for full-range bass (125–130 dB peak)
- Target 120–125 dB SPL with 6–10 dB headroom
- 90°–120° horizontal coverage; acoustic modelling ensures even distribution
- SSOUNDS systems prioritize vocal clarity and reliability for mid-size events
