Advent Large Advent Loudspeaker (1970)
An improved version of the original Advent speaker, with a 12-inch woofer and an enhanced crossover for deeper bass and higher output.
Overview
Advent Corporation introduced the Advent Large Advent Loudspeaker in 1970 as an updated successor to the original 1968 Advent Loudspeaker. It went deeper in the bass and could play louder than its predecessor, and it kept the brand's aim of high-fidelity sound at an accessible price. The available sources don't document frequency response, impedance or sensitivity. The Large Advent was positioned as a performance-oriented model in Advent's early lineup. It shared the design philosophy of the original, which followed Henry Kloss-influenced acoustic suspension principles, but the research doesn't confirm that enclosure type for the Large Advent itself.
Design
The key changes were the 12-inch woofer and a revised crossover network. Together they gave better low-frequency extension and system coherence. The verified sources say nothing further about cabinet construction, materials or driver composition.
Context
The Large Advent was part of a broader family of Advent speakers released in the early 1970s. It outperformed the original model. Smaller, cheaper alternatives followed, including the Advent/2 (1970) and Advent/3 (1972), for listeners short on space or budget. The Large Advent stayed the choice for maximum output and bass depth from the brand's early offerings.
