Bookshelf speakers designed by Henry Kloss, featuring an 8” long-throw woofer and 3/4” soft dome tweeter in a sealed acoustic suspension enclosure.

Overview

The Advent Graduate is a bookshelf speaker model produced by Advent Corporation during the 1980s. Designed by Henry Kloss, these speakers were positioned between the Advent Prodigy and Advent Baby lines and intended as a modernized replacement for the earlier “Smaller Advent.” Each speaker weighs about 19 lbs and features solid Pecan wood top and bottom trim pieces. The Graduate delivers a frequency response of 55–21,000 Hz and handles 70 watts RMS at 8 ohms. Known for clean, smooth highs and solid bass from the 8” woofer, the Graduate is described as a very enjoyable package and well-suited for smaller rooms, bedrooms, offices, or use as surround speakers.

Design

The Advent Graduate features an 8” long-throw woofer in a sealed acoustic suspension enclosure and a 3/4” polyamide soft dome tweeter, the same tweeter used in the Advent Baby. The design emphasizes acoustic suspension principles pioneered by Henry Kloss. Each speaker includes solid Pecan wood trim on the top and bottom, contributing to its distinctive appearance and structural quality.

Context

The Graduate was introduced during the 'golden age' of Advent, prior to the company’s shift to Chinese-designed models. Advent Corporation, founded in Cambridge, Massachusetts by Henry Kloss in 1967, was acquired by Jensen in 1979 and ceased operations in 1981. The Graduate slots into the brand’s product lineup between the Prodigy and Baby series and was developed as an updated successor to the Smaller Advent.

Market

Woofer foam surrounds commonly degrade over time and often require refoaming; repair kits with foam surrounds and adhesive are available. Historical sale prices include $59 for a pair in 2009 and $99 for a pair at an undated sale. A modified unit was listed for $35 plus shipping in 2022.
