Product details
The loudspeaker utilizes a direct-radiating design, and its compact air-spring enclosure ensures rapid low-frequency response.
When paired with a sound reinforcement system composed of small to medium-sized speakers, it perfectly achieves fast transient response, solid sound, and a clean, powerful output.
For greater sound reinforcement versatility, we also developed a matching active subwoofer, the "S400A," in the same size.
The enclosure is constructed from premium multi-layer birch plywood and coated with a waterproof polyurea finish, allowing for all-weather outdoor use.
