A loudspeaker component includes a unitary plastic element that defines at least a portion of (i) a first acoustic volume that can be acoustically energized by an electro-acoustic driver, (ii) a first port which extends from the first acoustic volume and conducts acoustic energy from the first acoustic volume towards an environment external to a loudspeaker in which the plastic element resides, and (iii) a second port which conducts acoustic energy from a second acoustic volume, defined by the loudspeaker, towards the external environment.
