It is suitable for either direct radiating or horn loaded applications as part of a 3 or 4-way auditorium, touring, or outdoor festival sound system. It is the result of an intensive development program which aimed to produce the best 10-in ferrite midrange driver available.The smooth curvilinear paper cone has a special high strength wood pulp composition & has been designed to achieve the best possible linearity within the middle frequency range & to control bell-mode resonances around the cone circumference. The cone is carried by a double half-roll suspension composed of a material which is more resistant to aging & fatigue than traditional materials, providing the correct damping & excursion control.
