Advent/3 (c. 1972)
The Advent/3 was a smaller, cheaper model in Advent's early-1970s speaker lineup. Henry Kloss designed it as a compact acoustic suspension system for tight spaces. Contemporary sources call it "perfect for dorm rooms and apartments" - a practical bookshelf speaker that gave Advent's house sound to listeners who couldn't fit the larger Advent/2 or the original Advent Loudspeaker.
Little detailed documentation survives. Here is what is known. The Advent/3 used a single 2-inch tweeter, which one owner said "punches well above its weight" - not silky or extended, but honest. It was mated to an acoustic suspension enclosure wrapped in walnut vinyl. Dimensions are approximately 16 inches tall, 10 inches wide, and somewhere between 6½ and 7 inches deep. The exact depth is inconsistently reported. No woofer size, crossover frequency, impedance, sensitivity, or power handling figures have turned up in period sources.
The model appears to have been produced from around 1972 through the mid-to-late 1970s. A forum post from a 2002 discussion recalls buying a pair "around 1979 or 1980," which suggests the Advent/3 may have stayed in production, or in retail channels, for some years after its introduction. The cabinets were styled like the utility-vinyl Advents of the era: plain, with no wood veneer.
Known specifications (what little is confirmed):
- Enclosure type: Acoustic suspension (sealed)
- Tweeter: 2-inch driver
- Dimensions (H × W): 16 × 10 inches
- Depth: Approximately 6½–7 inches (unverified)
- Cabinet finish: Walnut vinyl wrap
- Designer: Henry Kloss
The Advent/3 sits below the Advent/2 (1970) and the Large Advent in the brand's early hierarchy. It is smaller in every dimension and priced accordingly. No original price has been located, and no service literature, crossover schematics, or parts availability information has surfaced. Like many compact Advent models, surviving units may have foam surround rot, but that is not confirmed for the /3 specifically.
