Advent Large The Advent (1970)
An improved version of the original Advent Loudspeaker, featuring a 12-inch woofer and enhanced crossover in a larger sealed cabinet.
Overview
The Advent Large The Advent came out in 1970. It was an upgrade of the original Advent Loudspeaker from 1968. Advent Corporation built it. Audio pioneer Henry Kloss founded the company in Cambridge, Massachusetts in 1967, and it aimed at high-fidelity sound at an accessible price. This floor-standing speaker used acoustic suspension design with a 12-inch woofer in a larger cabinet than its predecessor. That gave it better bass performance and higher output capability. It also got an enhanced crossover network, part of what set it apart from the earlier model.
Design
The Large The Advent used a sealed (acoustic suspension) cabinet. Henry Kloss championed that design during his time at Acoustic Research and KLH. It gave tighter, more controlled bass than the ported designs of the era. The larger cabinet volume allowed greater air compliance, which supported the 12-inch woofer in delivering deeper low-frequency output without distortion. Advent's own advertising said the design improvements focused on extending bass response and increasing dynamic range while keeping the neutral, musical character of the "New England sound" - a lineage tracing back to Kloss's earlier work.
Context
The Large The Advent was an improved version of the original Advent Loudspeaker, and an early step in the brand's line of affordable high-fidelity speakers. It kept the same acoustic suspension approach but offered deeper bass and higher output capability, at the affordable price point that defined the company's mission. It came before later models like the New Advent (1977). Stereophile (January 1975, p.38) noted that Advent's designs "maintained a consistency of voicing across models, with an emphasis on natural tonality and absence of artificial brightness."
