Mirage OM-7 loudspeaker
Mirage is a good name for a speaker manufacturer; it suggests that their products produce realistic illusions. A 1934 dictionary I've got supplies a definition for "mirage" that might also be apt: "An optical atmospheric illusion by which the image of a distant object is seen as if inverted." I don't mean that the Mirage OM stands Harry Belafonte on his head, or make him sing "O-Day"—instead, certain tenets of cones-in-a-box loudspeaker design and usage are turned turvy-topsy by Mirage's Omnipolar concept.
