Features

• Bass radiator. also known as a drone cone. for replacing the inverted tube or subwoofer with the radiator and the traditional back subwoofer.
• A passive radiator system uses the sound otherwise trapped in the enclosure to excite a resonance that makes it easier for the speaker system to create the deepest pitches
• Air turbulence noise is no longer an issue. when air rapidly escapes the pipe at high volumes.No more high frequencies reflected out the port.
• Passive radiators operate in conjunction with the active driver at low frequencies. sharing the acoustic load and reduce the excursion of the driver.
• Working similarly to a vent. the passive radiator will only add as much as they subtract.
