Its main specifications include an Impedance of 8ohm, a Sound Pressure Level (sensitivity) of 96dB/W (1m), and a rated power handling of 9W,

To provide reference values for enclosure design, the Lowest Resonance Frequency (fs, f0) is 54Hz, and the Reproduction Frequency Response range is ensured from fs to 18k Hz. Designed as a component for back-loaded horn enclosures, an Mms (m0) of 14.01g, and a Vas of 37.81L. The manufacturer-recommended enclosure type is a Back-loaded Horn.

The frame is made of Steel frame, the required baffle hole diameter is Φ185mm, it requires 4 mounting holes, the magnet weight is 1160g/unit, the total net weight is 4080g, the overall diameter of the unit is 208mm,

The FOSTEX FE-Σ-RE series is a modern revival of the original FE203Σ, blending its classic technologies with cutting-edge innovations. Designed specifically for back-loaded horn applications, this special limited-production unit maximizes the unique characteristics of back-loaded horn designs. It features a two-layer ultra-refined NUKP diaphragm, made with unbleached softwood kraft pulp. The core layer combines long and short fibers for optimal rigidity and internal loss, while the surface layer of short fibers enhances propagation speed. This achieves a rich and resonant tone with sharp transient response in the mid-to-high range and deep, full-bodied low frequencies, staying true to the legacy of the FE203Σ.
