How many line array boxes do I need?
Quick answer
The number of line array boxes you need depends on venue size, desired SPL, and coverage requirements, but a typical small-to-medium system starts with 6–12 boxes per side.
Determining the right number of line array boxes involves calculating coverage, SPL, and throw distance. For a typical small venue (up to 500 seats), 6–8 boxes per side often suffice. Medium venues (500–2,000 seats) may require 8–12 per side, while large outdoor events can need 16–24 or more per side. The key is to achieve even coverage with minimal overlap and sufficient headroom.
SSOUNDS line array systems are designed for scalability and consistent performance. Our engineering team recommends starting with a coverage prediction using EASE or similar software. Factors like venue shape, ceiling height, and audience area all influence box count. A rule of thumb: each box covers roughly 10–15 meters of throw, but this varies with model and configuration.
For precise sizing, consider the required SPL at the farthest listener. A typical line array box delivers 130–140 dB peak SPL. Subtract distance losses (6 dB per doubling of distance) and add headroom (6–10 dB). Then divide by the box's output to estimate quantity. Always consult with a professional system designer or use manufacturer prediction tools for accurate results.
Key things to consider
- Small venues (up to 500 seats): 6–8 boxes per side
- Medium venues (500–2,000 seats): 8–12 boxes per side
- Large outdoor events: 16–24+ boxes per side
- Use prediction software for accurate coverage and SPL
- Factor in venue shape, ceiling height, and audience area
