In-ceiling subwoofers sit flush within the ceiling, helping preserve the room’s visual design while providing low-frequency reinforcement for distributed speaker systems. Surface-mount subwoofers attach to a wall or other suitable surface, making access and placement more straightforward while adding a visible speaker enclosure to the room.

A 70V subwoofer uses a high-impedance distributed audio system, while an 8-ohm subwoofer connects to a low-impedance amplifier system. Choose the version that matches the amplifier, wiring method, and connected speakers, with 70V often fitting distributed commercial installations and 8-ohm models fitting conventional low-impedance systems.

Subwoofers can connect with full-range speakers through satellite outputs, helping reduce the number of amplifier channels required for the system. A built-in high-pass filter routes lower frequencies to the subwoofer and sends the remaining range to the satellite speakers, supporting smoother crossover and balanced playback.

For compact spaces, consider a 3.5-inch surface-mount subwoofer with SR-Bass technology, or an eight-inch in-ceiling model with a band-pass enclosure when a concealed installation suits the design. For stronger low-frequency output, a 10-inch surface-mount subwoofer with a bass-reflex enclosure provides added bass reinforcement, with options for 70V or 8-ohm systems.
