Product details:
SB-218 consists of a coil diameter of 4 inches (100mm) of 1200 watts in dual 18-inch woofers composed subwoofer, with relatively small volume of the box for easy installation and display a variety of environments. Case selection of high-quality high-density 18mm birch plywood production, to minimize large dynamic state resonance box; in order to obtain a lower nonlinear distortion and low-frequency limit, better low frequency flexibility and higher output, and unit cabinet design into a new concept and technology, environmentally friendly water surface with black multilayer waterproof fire-retardant paint, wiring board after two parallel Neutrik NL4MP socket, hexagonal steel mesh hole with a special sound-permeable mesh, to ensure the sound under the effective transmission, it provides better protection unit.
