How many subwoofers do I need for 300 people?
Quick answer
For 300 people at a typical event, 2 to 4 high-quality subwoofers (e.g., dual-18″ or single-18″) are usually sufficient, depending on venue size, music genre, and desired SPL.
The number of subwoofers needed for 300 people depends on several factors: venue size and acoustics, music style, and target SPL. As a rule of thumb, a pair of dual-18″ subwoofers can provide solid low-end for 200–400 people in a medium-sized room or outdoor space. For bass-heavy genres like EDM or hip-hop, or for larger open areas, four single-18″ subs may be preferable to ensure even coverage and headroom.
SSOUNDS engineers use advanced acoustic modeling and AI-assisted prediction to precisely calculate subwoofer requirements for each event. This ensures optimal coverage, minimal cancellation, and consistent low-frequency response across the audience area. For a 300-person event, a typical configuration might be two SSOUNDS dual-18″ subwoofers flown or ground-stacked, or four single-18″ subs arranged in an end-fire or cardioid array to control rear spill.
Always consider the subwoofer-to-mains crossover point and the physical placement. For even coverage, distribute subs symmetrically or use a subwoofer array design. If you’re unsure, a good starting point is 1–2 subs per 100 people for moderate SPL, scaling up for higher output or larger venues.
Key things to consider
- For 300 people, 2 dual-18″ or 4 single-18″ subwoofers are typical.
- Adjust based on music genre: more subs for bass-heavy content.
- Place subs symmetrically or use cardioid arrays for even coverage.
- SSOUNDS offers precise modeling to match subs to your specific venue.
- Always allow headroom: better to have slightly more than too little.
