This 10 inch 8 ohm speaker features a FEA optimized ferrite magnet motor, a 2 inch high-temperature voice coil, a vented yoke for motor cooling, and a high strength stamped steel frame. It also features a Kevlar loaded non-pressed paper cone to help dampen and control cone resonance. The multi-roll surround and spider have been optimized to reduce distortion over the excursion range of this transducer.
