How many subwoofers do I need for 5,000 people?
Quick answer
For 5,000 people, you typically need 8 to 16 high-power subwoofers, depending on venue type, SPL requirements, and coverage pattern.
The number of subwoofers for a 5,000-person event depends on factors like venue (indoor vs. outdoor), music genre, and desired low-frequency impact. A common rule of thumb is 1 subwoofer per 300–600 people for moderate SPL, or 1 per 150–300 for high-impact bass. For 5,000 people, this translates to 8–16 professional-grade subwoofers.
SSOUNDS engineers use acoustic modelling software to precisely determine subwoofer count, array configuration (cardioid, end-fire, or left-right), and placement. For outdoor events, you may need more subwoofers to overcome lack of boundary loading, while indoor venues benefit from room gain. Target SPL at the listening area is typically 125–135 dB peak for rock/EDM, or 115–125 dB for speech/corporate.
A practical starting point is 12 subwoofers (e.g., SSOUNDS dual-18” models) for a 5,000-person outdoor concert. For indoor events, 8 may suffice. Always allow for headroom and even coverage; multiple smaller subwoofers often outperform fewer larger ones in uniformity.
Key things to consider
- Rule of thumb: 1 sub per 300–600 people (moderate) or 1 per 150–300 (high-impact).
- For 5,000 people: 8–16 subwoofers typical; start with 12 for outdoor, 8 for indoor.
- SSOUNDS uses acoustic modelling for precise sizing and array configuration.
- Consider venue type, music genre, and SPL targets (115–135 dB peak).
- Multiple smaller subs improve coverage uniformity over fewer large ones.
