Cuboid 15 is a full range, two-way, passive, 15” loudspeaker designed to perform. For any applications requiring big output, it effortlessly delivers rich and detailed sound with extra punch and precision. With its steel grille and optional mounting hardware the professionally presented Cuboid 15 can be fixed in either portrait or landscape mode for a flexible, simple installation.
