The carbon-based diaphragm results in a highly-responsive and detailed driver that can easily handle quick transients with minimal distortion thanks to minimal breakup during driver movement. Full of energy, always ready to go Asymmetrical internal and external magnetic circuits The new FD11 employs second-generation asymmetric internal and external magnetic circuit systems. Through the use of finite element simulation, the FD11’s dual magnetic circuit design has been optimized to generate a stronger magnetic field compared to a typical dynamic driver’s single internal or single external magnetic circuit system. This results in a higher magnetic field density, allowing the diaphragm to be more powerfully driven for a more “robust” sound with better transient response. Experience robust, quick bass! Dual cavity dynamic driver The rear of the FD11’s dynamic driver features a unique dual-layer cavity, allowing the development team to install damping control systems in both the inner and outer chambers to precisely control air flow – resulting in reducing distortion and allowing the diaphragm to move more freely without breakup. This results in both more detailed treble and especially more robust and more resolving bass, with the driver faithfully reproducing low-frequency details with astonishing speed. Classy craftsmanship on display Liquid die-cast zinc alloy construction Affordable price, high-end craftsmanship – this is what you get with the FD11. FiiO took the “conch” as its inspiration for the FD11 design. Zinc alloy is the material of choice for constructing the FD11 in order to give it a unique flowing appearance. This zinc alloy is die-cast into its shape, and then polished and electroplated to give it a high-end look and feel rarely seen in its class. A C-shaped talent C-shaped acoustic flute In addition to the new conch-like shape of the FH11, the C-shaped acoustic flute within the FD11 also serves to notably enhance sound quality – this feature specifically focuses on the bass. When air moves through the internals of the FD11, the C-shaped acoustic flute helps to increase the viscosity of that air and reduces the resonance frequency, which helps to improve both mid-bass and sub-bass quality. What this means is now you can clearly feel the cohesiveness and power behind the sound of drums beating. Tailor-made, for pure brilliance Fine-tuned frequency response The development team has placed special care in making sure the dynamic driver produces a smooth, easy-to-listen sound thanks to continuous, science-driven efforts. Even though the FD11 features a single dynamic driver, that dynamic driver’s light carbon-based diaphragm not only allows it to handle bass frequencies with aplomb, the driver also is capable of producing sound with specially optimised emphases at certain points like 14kHz and 18kHz that allow it to clearly reproduce the details in your music. * Measuring equipment: B&K HATS (Head & Torso Simulators), APX555 audio analyser 0.78mm dual-pin detachable cable The FD11 uses a 0.78mm dual-pin cable, allowing you to easily upgrade your listening experience later. The elbow-shaped headphone connector is also specially curved to make it both easier to use and more comfortable to wear. Hi-Res Audio certified The FD11 is Hi-Res Audio certified, as established by the Japan Audio Society (JAS) and Consumer Electronics Association (CEA). It is a testament to the FD11’s ability to accurately reproduce audio the way it was meant to be heard.
