What is the best line array for 100 people?
Quick answer
For 100 people, a compact 2-way line array like SSOUNDS’s mini-format systems with 2-3 boxes per side and a single 18-inch subwoofer delivers clear, even coverage and sufficient SPL for small venues.
For an audience of 100, the priority is even coverage and speech intelligibility rather than extreme SPL. A typical rule of thumb is 1–2 line array boxes per side for every 50–100 people, so a small 2-way line array with 2–3 enclosures per side (e.g., SSOUNDS compact line array) paired with one 18-inch subwoofer is more than adequate. This setup achieves 100–110 dB peak SPL at the listening area, which is comfortable for spoken word and moderate music.
SSOUNDS engineers use AI-assisted acoustic modeling to optimize coverage for each venue, ensuring that every seat gets consistent sound. For 100 people, the array height is typically 2–3 meters, with a splay angle of 0–2° between boxes to maintain uniform coverage. The subwoofer can be placed centrally or flown to avoid phase issues. This approach avoids over-specification and keeps the system portable and cost-effective.
Key considerations: avoid large subwoofers (dual 18-inch) that overpower the room; instead, use a single 18-inch or a compact 15-inch sub. Ensure the line array has a wide horizontal dispersion (100°–120°) to cover the audience width. SSOUNDS systems are designed for such applications, offering high output in a small footprint with advanced DSP presets tailored to the venue size.
Key things to consider
- Use 2–3 compact line array boxes per side for 100 people; avoid more than 4 boxes per side.
- Pair with a single 18-inch subwoofer; dual subs are unnecessary and can cause low-end muddiness.
- Target 100–110 dB peak SPL at the listening area; higher SPL risks distortion and listener fatigue.
- Ensure horizontal coverage of 100°–120° to cover the audience width without gaps.
- SSOUNDS engineers use acoustic modeling to fine-tune array height, splay, and sub placement for optimal results.
