The sound tube also ensures the mid-bass is smooth and clean while enhances bass texture in general. Four-way crossoverThe 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.4th generation DLP 3D printingNow in its 4th generation, the printing accuracy, efficiency, and curing uniformity have been significantly improved from the past iterations of DLP 3D printing. This allows the FA9 to have an extremely precise and robust structure that is fully optimized for audio that is difficult to achieve with traditional manufacturing methods.
