Descripción
The FR-400S is a 6-inch speaker with a nominal impedance of 4 ohms, designed to deliver outstanding performance across a wide frequency range, from mid-bass to highs, in sound systems. The precise selection of its components ensures a broad frequency response.
One of this model's key features is the replacement of the traditional dust cap with a phase plug at the pole center, providing cleaner and more defined high-frequency reproduction. Additionally, it reduces harmonic distortion and enhances voice coil ventilation, allowing it to operate at lower temperatures, which contributes to greater durability and superior performance.
