It has been designed for midrange & midbass frequency reproduction in horn-loaded, as well as bass-reflex compact enclosures. The transducer's extremely powerful neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange. The levels of force factor & power handling result in the best power to weight ratio on the market today.12ND610 curvilinear paper cone has been designed by 18 Sound engineers with a special high-strength wood pulp to achieve the best possible linearity within its intended frequency range & to control bell-mode resonances around the cone circumference. Its cone is capable of carrying significant loadings thanks to a dedicated reinforcing treatment. The cone is carried by a multiroll suspension built from a linen-like material which is more resistant to aging & fatigue than traditional materials.
