JWT has more than 10+ years experience in customizing Bass Radiator for any application with satisfied quality The silicone part includes pure silicone solid parts, liquid silicone parts, LSR, HTV silicone, and so on.
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
Bass radiator, also known as a "drone cone", for replacing the inverted tube or subwoofer with the radiator and the traditional back subwoofer.
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.
Passive radiators can be used to reduce the size of the speaker cabinet, as they do not require the same amount of internal volume as a traditional bass driver.
Passive radiators can be designed to match the frequency response of the active driver in the speaker system, providing a more seamless transition between the two drivers.
Passive radiators can be tuned to a specific frequency range by adjusting the mass of the diaphragm or the compliance of the surround.
