TANCHJIM KASIER

The acoustic system features a 10mm DMT 5 dual-cavity dynamic driver purpose-built for bass, paired with four TANCHJIM-developed PURE Series balanced armature drivers (2 mid + 2 high). The dynamic driver uses a narrow magnetic gap, high-flux magnetic circuit, and a long-excursion diaphragm to deliver deep-reaching bass with solid weight and clearly defined layers. For the BA drivers, strict control over armature positioning and coil winding minimizes variations in electroacoustic performance, reducing nonlinear distortion and improving transduction performance. KASIER uses a high-precision three-way crossover that combines acoustic tubing with an analog filter network. Frequency division is defined not only by the electrical circuit, but also by the acoustic path of each driver. Driver response, tube acoustics, and the crossover network are tuned together as one system. Using finite element analysis (FEA), TANCHJIM modeled and refined sound-tube angles, acoustic paths, and acoustic impedance to preserve the intended acoustic filtering, reduce transmission loss, and align each acoustic path precisely with its assigned frequency range. KASIER continues KARA's design language with a clear shell, a silver-toned faceplate, and a subtle blue accent. The transparent window reveals the internal layout, making the wiring and crossover board part of the visual design. Its high-precision DLP-printed medical-grade resin shell is engineered to balance resilience and rigidity. Precisely defined PCBA mounting points and component positions keep the internal routing consistent, improving assembly consistency and ensuring the internal layout is reproduced accurately throughout production.
