Description

• A passive radiator system uses sound that would otherwise be trapped in the enclosure to excite a resonance that facilitates the speaker system to deeper tones.
• Bass radiator, also known as 'drone cone', to replace the inverted tube or subwoofer with the traditional rear radiator and subwoofer.
• Noise from air turbulence is no longer a problem when air quickly escapes from the pipeline at large volumes and no more high frequencies are reflected in the port.
• Passive radiators work together with the active controller at low frequencies, sharing the acoustic load and reducing the excursion of the controller.
• Working similarly to a vent, the passive radiator will only add so much remain.
