Totem Acoustic KIN Sub?
Passive radiators have mass and compliance and so function in the same way as the port in a ported loudspeaker.
The air in the port has mass and compliance and can be used to tune the bass response of the system.
The ported or passive radiator system has a 4th order response -24 dB/Octave as compared to a sealed box system which has a -12 dB/Octave response.
The advantage of a passive radiator is its large radiating surface area and ability to operate in a smaller enclosure.
