Description

Designed by Advent founder Henry Kloss and voiced by future Boston Acoustics founder Andy Kostatos, this 1972 classic remains a benchmark for natural, detailed bookshelf sound.

The Smaller Advent debuted in 1972 as a more affordable version of Kloss’s original Advent Loudspeaker, aiming to bring serious audiophile performance into a smaller cabinet without sacrificing the sonic character that made the larger model famous. It quickly became one of the best-selling speakers of its era and earned wide critical praise, a reputation later reaffirmed by Stereophile’s 2006 retrospective review of a well-preserved pair. That review highlighted the speaker’s exceptional midrange detail, transient articulation, and surprisingly deep bass extension for its size, output achieved through pure acoustic-suspension design rather than any reflex porting.

Each speaker pairs a 9.5-inch paper-cone woofer with a distinctive 2-inch paper-cone dome tweeter (affectionately nicknamed the “fried-egg” tweeter by collectors), crossing over at 1,500 Hz for Kostatos’s carefully voiced blend. Built rock-solid with quality binding posts, these speakers were engineered as genuine audiophile gear at an accessible price point, a philosophy that helped define what one Stereophile writer called the “New England School” of speaker design. This pair presents in Good cosmetic condition, showing honest wear consistent with a speaker now over 50 years old, it has been thoroughly inspected and tested to confirm full functionality.
