FiiO FA7S Six Balanced Armature IEM Review
January 31, 2023 Comments Off on FiiO FA7S Six Balanced Armature IEM Review
Rather than relying on a single driver to manage the entire frequency range, the FA7s divides it between six distinct balanced-armature drivers. This is intended to permit a quicker, more precise, and more detailed performance. From my understanding, The low- and high-frequency drivers are off the shelf from Knowles, while the mid-frequency one is a custom model designed solely for FiiO.
Dividing the frequency range between six drivers is not a simple task. If not done correctly, it may lead to an unnatural overlap of certain frequencies, as the drivers usually produce higher and lower frequencies than their assigned range.
