Reflex port
The distinctive feature of a very popular variety of loudspeaker enclosures (Bass reflex) is the reflex port which enhances the reproduction of the lowest frequencies generated by the woofer. The port generally consists of one or more tubes mounted in the front (baffle) or the rear side of the loudspeaker. This allows extending the (deep end of the) frequency response of the system , which means that the loudspeaker can reproduce the sound of musical instruments that generate bass in a better way than that of an equally sized sealed enclosure.
Though advantageous in regards of deep bass, the bass reflex cabinet is known to have poor transient response compared to the sealed enclosure cabinet. Achieving a balanced bass reproduction from a sealed box is also simpler than properly aligning the components of a bass reflex system.
