How many speakers do I need for 5,000 people?
Quick answer
For 5,000 people, a professional system typically uses 8–12 line array enclosures per side plus 8–16 subwoofers, depending on venue shape and SPL requirements.
Coverage is the primary factor: a standard line array element covers about 120° horizontal and 10–15° vertical. For a typical audience width of 40–60 meters, you need at least 8–12 boxes per side to achieve even coverage from front to back. SSOUNDS engineers use acoustic modelling software to calculate exact box counts based on throw distance and desired SPL.
SPL targets for 5,000 people range from 100–105 dB average with 10–15 dB headroom. A single SSOUNDS line array element can produce up to 140 dB peak, so 12 boxes per side easily achieve 110 dB+ at 50 meters. Subwoofer count depends on bass impact: for rock/EDM, 12–16 single-18” subs (cardioid or end-fire) are typical; for speech, 4–8 may suffice.
Practical rule-of-thumb: for outdoor festivals, 8–12 boxes per side + 8–16 subs; for indoor arenas, 6–10 per side + 6–12 subs. Always add delays for long, narrow venues. SSOUNDS provides free system design support to optimize box count and rigging for any venue.
Key things to consider
- 8–12 line array enclosures per side for even coverage
- 8–16 subwoofers depending on music genre
- Target 100–105 dB average with 10–15 dB headroom
- Use acoustic modelling for precise deployment
- Consider venue shape: delays may reduce main hangs
