卓苧’s new flagship hybrid IEMs, the FH9, is the result of two years’ worth of intense research on how to fully take advantage of the strengths of hybrid IEMs and push the boundaries of what they can sound like. This 1 dynamic 6 BA driver design (7 in total) features a 2nd generation 13.6mm DLC diaphragm dynamic bass driver fully capable of extending to the lowest frequencies with ample punch. Mid and high frequencies are handled by a custom 6 Knowles BA setup that accurately reproduces every last musical detail. Together, these drivers provide a rich and detailed musical soundscape fully befitting a flagship.
"The advantage of multi-unit products is that they can extract the advantages of different units and combine them. FH9 not only uses large-size moving coil units, but also uses Lou's ultra-high frequency moving iron units. The frequency response coverage is very wide and the energy density is large. This is very important for the playback of small energy information; for example, the ultra-high frequency energy is small, but it is extremely important, there is no sense of space, so better resolution requires sufficient sound density. If the density is enough to hear the string, it will feel sticky, the wind will be thick and full, and the percussion instrument will feel air vibration when it is knocked. The instrument and the human voice will sound more stable, more solid, and more like real sounds."
