Advent Model Prodigy
Little is documented about the Advent Prodigy. What survives comes from a single period review. It describes a loudspeaker system with a 10″ black cone woofer, a 2″ mica-filled polypropylene-dome midrange, and a 1″ tweeter of the same material as the midrange. HiFI-Stereo (February 1987, p.126) reported crossover frequencies of 450 Hz and 3,750 Hz, an efficiency rating of 0.7%, and a power-handling range of 30-200 watts. Resonance was given as -3 dB at 39 Hz, with a frequency response of 38-22,000 Hz.
The cabinet was described as walnut veneer with a hand-rubbed oiled finish, topped and bottomed with solid pecan, and fitted with an anti-diffraction baffle cover. Dimensions measured 28.62″ high by 10.5″ wide by 10.5″ deep. Beyond this review, almost nothing else has survived in the public record - no production years, no original price, no family-lineup context.
