How many subwoofers do I need for a conference?

The number of subwoofers needed for a conference depends on room volume, audience size, and the type of content. For speech-only events, subwoofers are often used to add warmth and presence to the lower vocal range (around 80–100 Hz). A single 18-inch subwoofer can cover up to 200–300 people in a medium-sized room, but for even coverage and headroom, two subs are recommended. In larger halls (500+ capacity), four or more subs may be needed to avoid dead spots and ensure consistent bass response.

SSOUNDS recommends using subwoofers in a cardioid or end-fire array to reduce low-frequency buildup on stage and improve clarity for the audience. For conference applications, a 2:1 ratio of tops to subs is common—e.g., two tops with two subs. Always consider the subwoofer's power handling and sensitivity; SSOUNDS subwoofers are designed for high output with low distortion, making them ideal for clear, controlled bass in speech and presentation settings.

Room acoustics also play a key role. A reverberant room may require fewer subs, while a dead room might need more to achieve the same perceived level. Use subwoofer placement and DSP to optimize coverage. SSOUNDS provides system design support to help you calculate exact requirements based on your venue.
