Product Description:
This 2 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 stiff steel basket with
venting under the spider to aid cooling of the motor, a ferrite 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
roll rubber surrounds, which allow for a dynamic linear response to high excursion
input signals.
