How many subwoofers do I need for a restaurant?
Quick answer
For a typical restaurant, 1 to 2 high-quality subwoofers (e.g., single 18-inch) are usually sufficient to provide smooth, even bass coverage without overwhelming the space.
The number of subwoofers needed for a restaurant depends on the venue size, layout, and desired bass impact. For most small to medium restaurants (up to 200 seats), a single 18-inch powered subwoofer placed strategically (e.g., near a corner or under the bar) can deliver balanced low-end for background music or casual dining. For larger spaces or if you want more punch for events, two subwoofers can be positioned to reduce standing waves and improve coverage.
SSOUNDS recommends using a single high-output subwoofer like our 18-inch models for clean, controlled bass that won't disturb conversation. In open-plan restaurants with high ceilings or hard surfaces, a single sub can couple with the room to produce ample low frequencies. For L-shaped or segmented spaces, two subs may be needed to avoid dead spots. Always consider local noise regulations and the type of music—jazz or acoustic requires less subwoofer output than pop or electronic.
Proper subwoofer placement is critical. Placing a sub in a corner increases output by up to 6 dB due to boundary loading, allowing you to use fewer subs. Avoid placing subs directly under seating or near kitchen equipment to prevent rattling. SSOUNDS engineers can model your restaurant's acoustics to recommend the exact subwoofer count and placement for optimal performance.
Key things to consider
- For most restaurants (up to 200 seats), 1 high-quality 18-inch subwoofer is sufficient.
- Use corner placement to maximize output and reduce the number of subs needed.
- For larger or irregularly shaped spaces, 2 subwoofers improve coverage and reduce dead spots.
- Choose a subwoofer with a tight, controlled response to avoid muddy bass that interferes with conversation.
- Consider local noise ordinances and the restaurant's primary music style when selecting subwoofer power.
