The high strength (BL2\/Re) motor structure features optimised symmetry and excursion controlled by the Inner Flux Demodulating Ring. The robust copper 100mm (4\u201d) voice coil is wound in two different layers both outside and inside the coil support, thereby doubling the coil surface exposed to air cooling and consequently improving the long term thermal capacity of the loudspeaker. The cone is made of very high stiffness glass fiber reinforced paper, featuring also invisible water repellent treatment.The 15mm phenolic birch plywood cabinet is provided with a M20 pole mount socket to allow two-way ED series loudspeakers to be mounted above on standard speaker poles. Recessed handles are provided for easy lifting and handing, and the included polyurethane wheels aid transportation, while stacking feet and matching recesses enable secure ground stacks. Two Neutrik\u00ae speakON&#x2122; NL4 connectors provide input and link connections.KEY FEATURES\u2022 High power compact subwoofer\u2022 18\u201d woofer, 4\u201d voice coil\u2022 Water repellant cone\u2022 Heavy duty wheels\u2022 Pole mount socketAPPLICATIONS\u2022 Corporate and A\/V\u2022 Live music venues\u2022 Nightclubs and bars\u2022 House of Worship"}
