This 10 inch, 8 ohm speaker features a FEA optimized ferrite magnet motor, a 1.5 inch high-temperature voice coil, and a high strength stamped steel frame. 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.
