J18S

Product type: 【Sub-bass Series】
Product Profile:The J18S is a single 18-inch low-frequency speaker composed of one high-power, high-sensitivity low-frequency driver. The cabinet structure consists of a rear chamber and a front chamber, which improves output sensitivity through secondary compression in the front chamber. Under standard conditions of 1 watt/1 meter, the sensitivity can reach 103 dB, with an effective working frequency lower limit of 30 Hz and a maximum peak sound pressure level of 138 dB. It is used as low-frequency compensation for the J12CBT line array speaker and as a low-frequency compensating speaker in high dynamic range sound reinforcement systems.

Product details

The speaker cabinet 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 cabinet features a 2mm thick perforated protective steel mesh, 

and it is lined with multilayer waterproof sound-permeable material, offering strong resistance to wear, water, and moisture. 

Four metal connecting rods are installed on both sides of the speaker, allowing for aerial suspension. 

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