  2. Loudspeaker enclosure - Wikipedia

    en.wikipedia.org/wiki/Loudspeaker_enclosure

    The enclosure or driver must have a small leak so that the internal and external pressures can equalise over time, to compensate for changes in barometric pressure or altitude; the porous nature of paper cones, or an imperfectly sealed enclosure, is normally sufficient to provide this slow pressure equalisation.

  3. Acoustic suspension - Wikipedia

    en.wikipedia.org/wiki/Acoustic_suspension

    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 ...

    en.wikipedia.org/wiki/Bass_reflex

    Bass reflex enclosure schematic (cross-section). RCA bass reflex shelf stereo speakers.. A bass reflex system (also known as a ported, vented box or reflex port) is a type of loudspeaker enclosure that uses a port (hole) or vent cut into the cabinet and a section of tubing or pipe affixed to the port.

  5. Transmission line loudspeaker - Wikipedia

    en.wikipedia.org/wiki/Transmission_line_loudspeaker

    A transmission line loudspeaker is a loudspeaker enclosure design which uses the topology of an acoustic transmission line within the cabinet, compared to the simpler enclosures used by sealed (closed) or ported (bass reflex) designs.

  6. Passive radiator (speaker) - Wikipedia

    en.wikipedia.org/wiki/Passive_radiator_(speaker)

    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 ...
