2Pcs 3" 70mm Bass Speaker Passive Radiator Auxiliary Rubber Vibration Plate Subwoofer DIY Repair

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 aKEY_TAB vent, the passive radiator will only add as much as they subtract.
