The F-BOX Series is a premium line of high-performance surface-mount box speakers designed to elevate your audio experience. Featuring our proprietary speaker units, these speakers deliver exceptional sound quality, sleek aesthetics, and effortless installation. With a variety of options, including 3.5-inch full-range speakers, 5-inch and 8-inch two-way speakers, and 8-inch subwoofers, the F-BOX Series is the perfect choice for any commercial or professional audio application.

The F-BOX series features a minimalist and flat design based on TOA's "Basic Shape" concept. By minimizing protrusions and unnecessary embellishments, it eliminates unintended shadows and reflections that create visual noise, allowing it to seamlessly blend into any environment.

From the initial planning stages, the F-BOX Series has been designed with a consistent aesthetic, considering the included fittings as part of the main body. Just like the main unit, the fittings feature a unified design, creating a simple and beautiful space that remains free from visual noise, regardless of the viewing angle.

The innovative design allows the speaker to be temporarily secured to wall-mounted brackets during setup. This smart feature frees up both hands for wiring and precise angle adjustments, eliminating the need to support the speaker's weight. The result? A dramatically safer and more efficient installation process that significantly reduces the risk of accidents or equipment damage.

Every model in the series, including the subwoofer, is designed to be compatible with both high and low impedance sound systems. This flexibility enables you to choose the optimal configuration based on the installation location, application, and wiring conditions, ensuring seamless integration into a variety of system designs. Whether you're working with high or low impedance setups, our products offer the adaptability you need to achieve superior sound quality in any environment.

The line-up features an 8-inch subwoofer that delivers a rich and powerful low-frequency experience, especially when paired with the F-03 and F-05 models. This combination creates an exceptional sound environment. Moreover, the subwoofer is designed to support both high and low impedance, making it an ideal choice for sound installations in various settings, such as retail stores and gyms. This dual compatibility ensures versatility and ease of integration into different audio systems.
