The W-218B is a manifolded, vented-box subwoofer designed for use with wave series enclosures.The loudspeaker complement consists of two custom-designed 4" voice coil, double suspension 18" drivers, The two woofers face each other in a manifold chamber at the center of the enclosure, resulting in increased low frequency efficiency (at slightly above boxtuning) and reduced distortion compared to conventional direct-radiating designs. High driving strength is provided by a massive, precision crafted magnetic assembly. Four steel handles are provided for easy lifting and carrying and four rubber feet are fitted to the bottom of the cabinet.The enclosure is constructed from 3/4" (18mm) birch plywood, screwed and glued together for maximum strength and rigidity, and includes a reticulated foam and steel mesh grille. It is finished in black semi-matt textured environmental freindly paint. A rear panel connector plate carries two Neutrik Speakon NL4MP for loop in and loop out connections to additional enclosures.
