This 2 inch 4 ohm member of the new TA family sets a high standard for compact full range drivers. Intended for applications such as television soundbars and other compact applications in mind. Design features in this family include a stiff steel basket with venting under the spider to aid cooling of the motor, a NdFeB magnet motor with copper cap to lower coil inductance, providing low distortion at low frequencies and extended high frequency response. A black anodized aluminium cone and a black anodized aluminium dust cap are employed on the driver, coupled directly to the voice coil.
