The ported cabinet demonstrates increased bass output in the 50–100 Hz range. On the right is a simulation of the low-frequency response of a typical 5" mid-woofer, the FaitalPRO 5FE120 [8] mid-woofer generated, obtained using WinISD, [9] for ideal sealed (yellow) and ported (cyan) enclosure configurations. The ported version adds about an ...

For example, in a ported subwoofer enclosure tuned to 30 Hz, one may wish to filter out ...
In the same way as a ported loudspeaker, a passive radiator system uses the sound pressure otherwise trapped in the enclosure to excite a resonance that makes it easier for the speaker system to create the deepest pitches (e.g., basslines). The passive radiator resonates at a frequency determined by its mass and the springiness (compliance) of ...
