Product Description

The D series emerges as a remarkable lineup of loudspeaker systems crafted with a fusion of cutting-edge loudspeaker computer design simulation technology, the latest in speaker application materials, and advanced processing innovations. These illustrious speaker units are impeccably optimized for high magnetic energy and minimized distortion, coupled with excellent ventilation and magnetic circuit cooling systems. The bass unit shines with a specialized damping coated cloth edge, a uniquely nonlinear thickness long-fiber paper basin, and a robust high-power sandwich voice coil. Furthermore, the integration of our latest adjustable delay symmetric protection circuit not only ensures unparalleled sound quality but also significantly enhances the reliability and durability of the product, making it a true masterpiece in audio technology.

The D-18P loudspeaker, a distinguished member of the D series, features a reflective low-frequency design with a strikingly new shape and surface treatment process. It houses a powerful 12-inch low-frequency driver and incorporates a sophisticated airflow management system originating from the box sides. The bass unit is equipped with a robust high-power Φ75mm voice coil, ingeniously wound with flat copper wire both inside and out. The voice coil's skeleton, crafted from high-strength TIL material, not only fortifies the coil's integrity but also amplifies its power handling capacity. The symmetrical magnetic circuit design effectively minimizes odd harmonic distortion in low-frequency units, delivering a supreme auditory experience that satisfies the human ear's craving for rich low-frequency sound quality.

Constructed with precision, the speaker box boasts 18mm thick imported multi-layer plywood and a unique wooden wedge structure, achieving a flawless assembly without nails. Its surface is enveloped in resilient polyurethane paint, offering formidable resistance to wear. The box's tensile strength reaches an impressive 4500N. The speaker's surface mesh, made from Q236, is enhanced by a state-of-the-art powder spraying process, ensuring not only high strength but also excellent salt spray resistance. The mesh withstands exposure to 5% sodium hydroxide for up to 96 hours, ensuring rust-free use for 5 years under adverse conditions. Internally, the iron mesh is lined with sound-absorbing cotton, effectively shielding against rain and dust while achieving aesthetically pleasing acoustics.

This versatile sound equipment finds its place in a myriad of settings: bars, theaters, multifunction halls, churches, educational institutions, and both large and medium-sized sports venues, as well as indoor and outdoor events, delivering unmatched sound experiences effortlessly.
