How many subwoofers do I need for a restaurant?

The number of subwoofers needed for a restaurant depends on the room's square footage, ceiling height, layout, and the type of music or ambiance you want. For a small to medium restaurant (up to 1,500 sq ft), a single 12-inch or 15-inch powered subwoofer placed near the main listening area often provides balanced low-end coverage. For larger spaces (1,500–3,000 sq ft) or if you want more even bass distribution, two subwoofers—ideally positioned in opposite corners or along the same wall—can reduce dead spots and improve consistency.

SSOUNDS recommends starting with one high-quality subwoofer and evaluating coverage. If you notice uneven bass or need more impact for background music or events, add a second unit. Avoid over-subscribing, as excessive bass can disturb conversations and diners. For restaurants with live music or DJ sets, consider a pair of 15-inch or 18-inch subwoofers for headroom. Always match subwoofer power and frequency response to your main speakers (e.g., SSOUNDS point-source or line array systems) for seamless integration.

Placement is critical: keep subwoofers away from walls and corners to avoid boomy, uncontrolled bass, or use boundary loading intentionally for more output. Use a DSP or system processor (like SSOUNDS amplifiers with built-in DSP) to set crossover points (typically 80–120 Hz) and apply EQ to tame room modes. For restaurants with multiple zones, a single subwoofer per zone may suffice, but a distributed design with multiple small subs often yields better results than one large unit.
