Abstract
A speaker assembly comprising an elongated unitary member having a first end and a second end. The elongated member is formed into a generally box-shaped configuration having an open top, an open bottom and an internal box cavity. The first and second ends of the elongated member are separately positioned within the internal box cavity to form first and second internal sidewalls, respectively. First and second internal sidewalls define a sound path therebetween which is in communication with the internal box volume and an external portion of the elongated member. A first speaker is disposed in the first internal sidewall and a second speaker is disposed in the second internal sidewall, with first and second speakers facing directly into the sound path. A top panel is mounted on the elongated member over the open top and a bottom panel is mounted on the elongated member under the open bottom. In use, first and second speakers produce directly radiated and resonantly radiated sound waves which propagate out from the speaker assembly through the sound path.
