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 ...
This also minimizes the negative effects of acoustic energy that would otherwise (as with a sealed enclosure) be reflected back to the driver in a sealed cavity. [ 9 ] Transmission line loudspeakers employ this tube-like resonant cavity, with the length set between 1/6 and 1/2 the wavelength of the fundamental resonant frequency of the ...
In combination with the damping properties of the system (both mechanical and electrical) all these factors affect the low-frequency response of sealed-box systems. The response of closed-box loudspeaker systems has been extensively studied by Small [10] [11] and Benson, [12] amongst many others.
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 ...

Two-inch port tube installed in the top of a Polk S10 speaker cabinet as part of a DIY audio project. This port is flared. Unlike closed-box loudspeakers, which are nearly airtight, a bass reflex system has an opening called a port or vent cut into the cabinet, generally consisting of a pipe or duct (typically circular or rectangular cross section).
