What is the best line array for 100 people?
Quick answer
For 100 people, a compact line array like SSOUNDS’s small-format system (2-3 boxes per side, 1-2 subs) delivers clear, even coverage at moderate SPL, ideal for indoor events up to 500 sq. ft.
For an audience of 100, you don’t need a large-scale rig. A compact line array—such as SSOUNDS’s small-format system—with 2-3 enclosures per side and 1-2 subwoofers provides ample headroom and consistent coverage. Target 95-100 dB SPL at the listening position, with 6-10 dB of headroom for peaks.
SSOUNDS engineers use acoustic modelling to optimise box count, splay angles, and sub placement for your specific venue. A rule of thumb: one line array element per 30-50 people for speech, or per 20-30 for music. For 100 people, a single flown array per side or a ground-stacked pair works well.
Subwoofer count depends on bass content: one 18-inch sub per side (or a cardioid array) for general music, two per side for electronic or hip-hop. Always measure and tune with system software to ensure phase alignment and even coverage across the audience area.
Key things to consider
- Use 2-3 small-format line array boxes per side for 100 people.
- Target 95-100 dB SPL with 10 dB headroom for clean, intelligible sound.
- Add 1-2 subwoofers (18-inch) depending on bass requirements.
- Model the system with software (e.g., SSOUNDS prediction tools) for precise coverage.
- Keep arrays low (6-10 ft) for intimate venues; fly or stack as needed.
