Phoenix Gold ZXT8PR 8 Inch Passive Radiator For Extra Bass To Your Enclosure. The ZXT8PR passive radiator is formed from the main components of a subwoofer minus the motor structure and voice coil, this component is used to enhance the output of a bass enclosure in both volume and low bass dynamics. Passivate radiators are often seen in home audio setups to add the lower bass rumble without compromising additional space, they are fitted alongside a powered subwoofer, and the internal pressure of the bass enclosure which is sealed moves the passive radiator to generate sound and air pressure. Stamped low resonance steel basket. Inverted PP dust cap for additional cone area. Tuned weight for Excursion control. Rubberized gasket for an airtight seal.
