SPECIFICATIONS :

• The 18iD200 is an 18-inch neodymium ultra high-performance subwoofer.
• The transducer has been optimized for any subwoofer cabinet designs, even the most compact and is recommended for being driven by a Class D or iPal amplifier able to deliver 3600 watts program power without clipping on 2ohms loads.
• 18 Sound engineers have obtained the best possible results with today's available materials in terms of clean and undistorted LF reproduction at an ultra-high SPL.
• The 18iD200 design features include a large displacement suspension system specifically designed for matching the composite fibre reinforced, straight ribbed cone.
• Double silicon spider DSS technology, the 18iD200 is able to control the moving mass with high linearity, showing an exceptional stability of mechanical parameter values in the long term.
• Bl force factor, as well as all other electro-dynamic parameters, are linear within the working range.
• The 18iD200 has been developed after intense FEA and fluid dynamics simulation and testing, focusing on dissipating the heat generated by the powerful voice coil.
• Special attention was given to the optimization of air flow into the gap without introducing audible noise.
• A low-density material air diffractor placed into the heatsink acts as a cooling system, increasing the power handling capability and lowering the power compression figure.
• Overall Diameter: 462 mm 18.19 in.
• Bolt Circle Diameter: 440 mm 17.32 in.
• Baffle Cutout Diameter: 417.0 mm 16.42 in.
• Depth: 238 mm 9.37 in.
• Flange and Gasket Thickness: 24 mm 0.94 in.
• Net Weight: 16.0 kg 35.27 lb.
• Shipping Weight: 16.6 kg 36.6 lb.
