This 2 inch 4 ohm full-range driver is intended for applications such as television soundbars and compact music systems. Design features include a damped plastic basket with venting under the spider to aid cooling of the motor, a neodymium magnet motor with copper cap to lower coil inductance, providing low distortion at low frequencies and extended high frequency response. An aluminium cone is employed on the driver, along with an aluminium dust cap coupled directly to the voice coil. Additionally, the cones come equipped with large roll rubber surrounds, which allow for a dynamic linear response under high excursion.
