Large Advent (1970–)
A floor-standing loudspeaker with a 12-inch woofer in a sealed cabinet, designed as an improved version of the original 1968 Advent Loudspeaker.
Overview
The Large Advent came out in 1970. Advent Corporation of Cambridge, Massachusetts built it as a direct upgrade to the original 1968 Advent Loudspeaker. The cabinet is larger, and the 12-inch woofer sits in a sealed enclosure. That keeps the brand's acoustic suspension approach, with tight, full-bodied bass. The crossover is enhanced and integrates the drivers better than the predecessor's, for a more balanced and dynamic sound. The Large Advent handles higher output and goes deeper in the bass, and it kept the affordable price that made Advent speakers popular with mainstream audiophiles.
Design
The sealed cabinet houses the 12-inch woofer, which is paired with a high-frequency driver. The improved crossover network was engineered to match the drivers better, giving smoother frequency transitions and reduced distortion. The cabinet is larger than the original Advent's, which gives more air volume and better bass. Exact dimensions and construction materials are not documented.
Context
The Large Advent served as the evolutionary bridge between the groundbreaking 1968 Advent Loudspeaker and the later New Advent (1977), which updated the design with refined drivers and cabinet aesthetics. By improving upon the original with a larger woofer and enhanced crossover, Advent maintained its reputation for delivering high-value, high-performance speakers during the 1970s.
