J218SUB Low Speaker

Product type: 【Sub-bass Series】
Product Profile:The J218SUB is a dual 18-inch low-frequency speaker, composed of two high-power 18-inch low-frequency drivers. It has an effective working frequency lower limit of 28Hz and a nominal impedance of 4Ω. Under these conditions, it can achieve a maximum peak sound pressure level of 141dB, making it suitable for applications requiring low-frequency reinforcement in high-dynamic, high-sound-pressure sound systems.

Product details

The box is made of custom European-grade multilayer plywood, with a surface coated in PCP (polyurea) chemical 

coating that fully complies with environmental protection standards.

The front of the box features a 2mm thick perforated protective steel mesh, lined with multiple layers of waterproof 

and sound-permeable materials, providing strong resistance to wear, as well as waterproof and moisture-proof 

properties.

The top of the box is designed with a limiting groove, and the bottom is equipped with elongated protruding foot 

pads to prevent displacement when multiple boxes are stacked.
