Product Description
This 2.5 inch 4 ohm member of the PLS family sets a high standard for compact full range drivers
intended for applications such as television soundbars and compact music systems. Design features in
this family 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. A black anodized aluminium cone is employed on
the driver, along with a black anodized aluminium dust cap coupled directly to the voice coil. Additionally,
the cones come equipped with special-designed large roll rubber surrounds, which allow for a dynamic
linear response to high excursion input signals.
