Product Description

The S series is a remarkable collection of loudspeaker systems, meticulously engineered by harnessing the latest innovations in loudspeaker computer design simulation technology. These products seamlessly integrate cutting-edge loudspeaker materials and processing techniques. Each speaker unit is optimized for superior performance, featuring high magnetic energy and minimal distortion, ensuring exceptional ventilation and cooling within the magnetic circuit system. The bass units are crafted with specially coated damping cloth edges and a nonlinear thickness long-fiber paper cone paired with a high-power sandwich voice coil. To complement this, our company's state-of-the-art adjustable delay symmetric protection circuit not only guarantees pristine sound quality but also significantly enhances the product's reliability.



 

Introducing the S218, the flagship reflective low-frequency speaker of the S series, showcasing a revolutionary design and advanced surface coating. This powerhouse consists of dual 18-inch low-frequency drivers, masterfully directing airflow through strategically placed side vents. Each bass driver boasts a formidable Φ100mm diameter high-power voice coil, intricately wound with flat copper wire inside and out, reinforcing its structural integrity with TIL material. This ingenious design not only fortifies the voice coil but elevates its power-bearing capabilities. The symmetrical magnetic circuit design dramatically reduces odd harmonic distortion, delivering low-frequency sound quality that meets the most discerning listener's expectations.


 

Constructed from premium 18mm thick imported multi-layer plywood, the S218's robust wooden wedge box design eliminates the need for nails. The polyurethane paint finish ensures outstanding durability against wear. Capable of withstanding a tensile force of 4500N, the speaker's surface mesh is made from Q236, boasting high strength and exceptional salt spray resistance. Undergoing a rigorous powder spraying process, it guarantees up to 96 hours of salt spray resistance (5% sodium hydroxide), ensuring five years of rust-free usage under practical conditions. The iron mesh interior is lined with sound cotton, ingeniously preventing ingress of rain and dust while enhancing acoustic aesthetics.


 

The S218 speaker is equipped with specially designed feet on its base, enabling seamless movement and durability during operation. This thoughtful design minimizes distractions, optimizing sound quality. Incorporating a plethora of innovative materials, the speaker features a high-density cloth edge on the diaphragm, ensuring versatile compatibility with an array of full-frequency speakers, making it suitable for a multitude of applications.
The S218 speakers are versatile marvels, ideal for a wide range of environments, including bars, theaters, multi-purpose halls, churches, educational institutions, and large to medium-sized sports venues, as well as indoor and outdoor performances of considerable scale.
