Product Description
The Audio SW-318B is a compact 18" subwoofer that delivers powerful ultra-low frequency response. The woofer and wooden cabinet design provide tight and precise bass response, making it an ideal match for the LY-15. The unit features a long-throw design with a high magnetic force to achieve extreme magnetic flux, enhancing efficiency. It is equipped with a 4" voice coil (38mm height), ensuring a stroke under continuous magnetic drive of 26mm/PP. The specially treated pulp fiber cone maximizes the rigidity and inertial displacement of the unit. Additionally, the triple heat-resistant copper flat wire reduces power compression caused by voice coil heating, comprehensively improving sound quality and performance.
