Abstract
A method including providing a mold cavity to produce an outer contour of an acoustic resonator and providing a mold core to produce an inner contour of the resonator. The inner contour corresponds to a plenum, and a connecting channel in fluid communication with the plenum. An insert fitting adjacent to the mold core defines a length of the connecting channel during injection molding of the resonator.
