FiiO FA19 New Flagship 10 Knowles BA Driver IEMs
Custom Knowles · enhanced bass BA drivers FiiOs goal was to create a truly monumental multi-BA driver IEM. They aimed to shake up the current market of flagship multi-BA driver IEMs and spent three years on refining it to do so. For the ten balanced armature drivers FA19, they collaborated deeply with Knowles. Together they built a custom enhanced bass balanced armature driver specifically for the FA19 to provide the listener with a deep low-frequency experience uncommon in multi-BA driver IEMs. Additionally, FiiO also worked closely with Knowles to optimize the mid and high-frequency drivers so tht they not only sound highly detailed but also pleasantly smooth. With the FA19 we carefully tuned all parts of the frequency response curve for a truly coherent and resolving sound. Welcome to a new world for multi-BA IEMs, and the FiiO FA19 will be your guide. 10 Knowles BA Design The FiiO FA19 was designed based on both science and actual listening tests. FiiO settled for using 4 custom Knowles bass BA drivers, 2 Knowles ED mid-BA drivers and 4 Knowles SWFK treble BA drivers per ear monitor. Having more drivers in an IEM does provide certain advantages. It significantly increases the energy density within a given frequency range, resulting in more detail reproduced. This is especially apparent during dynamic audio passages, where more drivers are better able to handle the nuances present, ensuring that the resulting sound is not compromised. Thus, the IEM is better able to faithfully reproduce the original sound. When tuning IEMs, it is important that there are ample energy reserves from the drivers so that the engineers have enough to work with to achieve their sound goals. This may simply not be possible with fewer drivers. Thus the FA19 employs the outstanding BA drivers. And the physical + electronic three-way crossover accurately segments different drivers working on different frequency ranges, resulting in a clear, reference monitor-like sound quality. The FA19 is an IEM that reaches the height of sound quality with a thunderous impact, being able to faithfully reproduce every last single audio detail. Negative feedback bass enhancement system With four custom-enhanced bass-balanced armature drivers per channel developed by FIIO in collaboration with Knowles, the FA19 boasts ample bass. Engineers creatively made use of the precise DLP 3D printing technology to create a shell that helps to guide this low-frequency energy into the earphone’s rear cavity, effectively lowering the resonant frequency there – essentially a negative feedback bass enhancement system. The result is a bass that reaches extremely deep, uncommon among IEMs of its class. Mid-frequency notch filter A smooth mid-frequency curve not only stems from the core unit’s quality but also results from meticulous tuning by professional acousticians. The FA19 employs two classic Knowles ED mid-BA drivers, known for their high resolution and favoured by demanding...
