What is the best line array for 100 people?
Quick answer
For 100 people, a compact 2-way line array like SSOUNDS’ small-format systems with 2-3 enclosures per side and a pair of 15-inch or 18-inch subwoofers typically delivers clear, even coverage and sufficient SPL for speech and music.
When sizing a PA for 100 people, the key is matching coverage and SPL to the venue. A small-format line array (e.g., a 2-way passive design with 6.5–8-inch LF drivers) can provide consistent horizontal coverage of 100–120° and vertical pattern control with just 2–3 boxes per side. This keeps the system compact while avoiding the uneven coverage of point-source speakers in wider rooms.
SPL targets for 100 people are modest: 95–100 dB continuous at the listening area is ample for speech and background music, with 105–110 dB peaks for live bands. A pair of 15-inch or 18-inch subwoofers (cardioid or standard) will handle low-end extension down to 40 Hz. SSOUNDS engineers use acoustic modelling to optimise box count, splay angles, and subwoofer placement for each specific room, ensuring even coverage without hot spots or dead zones.
For portable applications, a system with 2–3 line array elements per side plus a single sub per side can be flown or ground-stacked. SSOUNDS’ compact line arrays are designed for fast deployment and precise DSP tuning, making them ideal for small clubs, corporate events, or outdoor gatherings of 100 people.
Key things to consider
- Use 2–3 small-format line array enclosures per side for even coverage and pattern control.
- Pair with 1–2 subwoofers (15-inch or 18-inch) for full-range sound down to 40 Hz.
- Target 95–100 dB continuous SPL at listening area; 105–110 dB peaks for live music.
- SSOUNDS engineers perform acoustic modelling to optimise box count, splay, and sub placement.
- Compact line arrays are easier to transport and set up than larger point-source systems for this scale.
