Manufacture Description
80.6mm ultra-long sound tube Specially-designed acoustic filter
In order to achieve the purest sound performance and to ensure the multiple drivers do not interfere with each other, the FA9 employs a specially-designed, ultra-long sound tube 80.6mm in length. The sound tube acts as a low-pass filter that effectively filters out unneeded extra mids and highs from the drivers to ensure a seamless frequency response. The sound tube also ensures the mid bass is smooth and clean while enhances bass texture in general.
Four-way crossover Igniting a fire within your heart
The four-way crossover design has been applied so that each driver works perfectly in harmony with each other for seamlessly coherent low, middle, high, and ultra-high frequencies. With dynamic bass, crystal clear yet lush vocals, and extremely detailed yet pleasant treble, the FA9 will get you excited about your music again.
