Soundtube SM400I-BK 4 Inch Coaxial Surface Mount Speaker

Product Description

The SOUNDTUBE SM400I-BK is a 4-inch coaxial surface mount speaker finished in black. Coaxial drivers combine the woofer and tweeter in a single point-source assembly, delivering full-range audio from a compact footprint. Surface mount construction means the enclosure mounts directly to a wall or ceiling surface without requiring in-wall or in-ceiling cutouts. This speaker is suited for commercial and light commercial audio distribution installations where recessed mounting is not practical or permitted. Installation is typically handled by licensed low-voltage or audio-video contractors.

The SM400I-BK is intended for distributed audio systems in commercial environments such as retail spaces, restaurants, offices, lobbies, and similar venues. Its surface mount form factor makes it a practical choice for concrete, masonry, or finished surfaces where cutting is not an option. The black finish allows the unit to blend with darker ceiling and wall finishes common in commercial interiors.

Installation Notes

Installation should be performed by a qualified low-voltage or audio-video technician in accordance with applicable local codes and NEC guidelines for low-voltage wiring. Disconnect and de-energize the audio amplifier or distribution system before making any speaker wiring connections. Verify that the amplifier impedance and wattage rating are compatible with the speaker before applying signal. Secure the enclosure to a structurally sound surface using appropriate hardware for the substrate material.
