Product Description

18 Sound 18ID200 2-Ohm iPal 18 inch Neodymium Subwoofer 3600 Watts

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 (tm*) amplifier able to deliver 3600 Watt 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 a ultra high SPL, with the lowest possible power compression figure.

The 18iD200 design features include a large displacement suspension system specifically designed for matching the composite fiber reinforced, straight ribbed cone.

Thanks to the 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. This, together with the exceptional high excursion behavior, ±18mm linear Xmax - makes the 18iD200 an extremely low distortion, highly dynamic transducer.

The 18iD200 features a state-of-the-art 5,3" inside outside ISV copper voice coil enabling the 18iD to deliver extraordinary transient results. The 18iD200 has been developed after intense FEA and fluidodynamics 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.
