The unique driver configuration and enclosure geometry are meticulously engineered by acoustic experts to minimize phase interference and standing waves. By optimizing the spatial distance between high-frequency and low-frequency drivers and their acoustic radiation angles, the system ensures that the clarity of high frequencies and the power of low frequencies coexist harmoniously. This design delivers exceptional vocal intelligibility and instrument separation, even in acoustically challenging environments (e.g., meeting rooms with reflective surfaces), eliminating sonic muddiness and distortion.
A set suitable for approximately 30-60 square meters, which can be customized according to actual conditions.

Material introduction
The cabinet is meticulously constructed from high-density medium-density fiberboard (MDF), a material valued for its uniform internal structure and exceptional damping properties. These characteristics effectively absorb cabinet resonance and reduce sound coloration, ensuring pure and unadulterated audio reproduction. Joints are treated with multiple layers of imported automotive-grade putty for sealing, and undergo a precision pressing process to guarantee airtightness within the cavity. This meticulous craftsmanship prevents low-frequency looseness caused by air leakage, maintaining the tightness and power of bass notes. The surface coating process is particularly sophisticated: first, the cabinet is finely sanded to create a smooth texture, followed by the even application of **5 layers of eco-friendly water-based paint**. This not only forms a wear-resistant and scratch-proof protective layer but also imparts a warm and elegant visual texture to the cabinet, balancing practicality with aesthetic appeal.
