Acoustic waveguides can be used to improve audio performance of playback devices, such as a soundbar. Such a playback device can include an elongated body defining an outer perimeter with a forward surface, an upper surface, and a rounded edge between the forward surface and the upper surface. An up-firing transducer is configured to direct sound along an axis that has a vertical oblique angle with respect to a forward axis. A waveguide in fluid communication with the up-firing transducer includes a sidewall extending circumferentially around the transducer, the sidewall having a first end adjacent the up-firing transducer and a second end adjacent the outer perimeter, such that an opening defined by the sidewall has a larger area at the second end than at the first end. A rear portion of the sidewall is more steeply angled with respect to the axis than a forward portion of the sidewall.

A manufacturing process for a grille element of a media playback system is provided. In one embodiment a sheet of plastic is thermoformed into a desired shape. Holes may have been drilled into the sheet of plastic prior to being thermoformed. Once thermoformed into the desired shape, a coating is applied and cured via a subsequent heat treatment process that anneals the material to remove additional stresses in the material from thermoforming. Once formed and heat treated, the formed component can be bonded to profile substrates to help maintain the formed desired shape.
