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.

Camber Laser 3 Bookshelf Speakers – Made in Ottawa, Canada
Built in Ottawa, a short drive from where they now sit. A 6.5-inch Audax mid-bass on a translucent polypropylene cone and a 1-inch dome with a centre diffusor, in light grey bezels against a dark cabinet. Two-way rear-ported, 8 ohms, 10 to 100 watts, spring clips on the back — give them room off the wall. Grilles included; very good condition.
Paradigm Monitor 3 v3 Bookshelf Speakers – 8″ Woofer, Canada
An 8-inch woofer in a cabinet small enough to sit on a stand — a 210 mm ICP cone on a die-cast chassis, with a third-generation titanium dome on the Studio-series waveguide faceplate, crossed at 2.0 kHz. Low frequency extension to 38 Hz and 91 dB room sensitivity, so 15 watts drives them and 150 is just headroom. Built in Canada, in Black Ash. Very good condition.
PSB Century 300i Bookshelf Speakers – 6.5″ Woofer, Canada
MartinLogan Motion 15 Bookshelf Speakers – Folded Motion, Boxed
The reason to want these is the tweeter — MartinLogan's Folded Motion driver is a pleated ribbon rather than a dome, so it squeezes air out from between its pleats and barely has to move. A 5.25-inch aluminium cone below it, 92 dB sensitivity, and the high-gloss black clean of the swirls these show so readily. Original boxes included.
Polk Audio RTi6 Bookshelf Speakers – Real Wood, Bi-Wireable
JBL 62T Bookshelf Speakers – Rosewood Finish, Titanium Dome
Discounted for the aftermarket screw holes a previous owner left in the back panels, and very good everywhere else — original drivers, clean rosewood finish, both tested here. A mid-1980s two-way with a pure titanium tweeter that runs out to 23 kHz, and an easy 89 dB load that a thirty-watt vintage receiver drives properly.
Mission 731 Bookshelf — Made in England, Inverted Driver Design
Two things to tell you: a ding on the top side edge of one cabinet, and third-party binding posts a previous owner fitted to one speaker. Otherwise good — and the design is the interesting part, since Mission's inverted geometry puts the tweeter below the woofer to bring the two into step at seated ear height. Made in England.
Bowers & Wilkins WM2 Outdoor Speakers, Pearl White, w/ Brackets
On an outdoor speaker the condition is the whole story — these are almost never retired for how they sound, but for sun turning a white cabinet chalky and yellow, freeze-thaw working at the seams, and grilles blooming with rust. Pearl White shows all of it more plainly than black would, and this pair grades Very Good, factory wall brackets included. B&W did not design a weatherproof box and then find a driver to fit it either: a 130 mm woven fibreglass cone crossed at 3.5 kHz to a 25 mm dome, the same material philosophy as their indoor speakers.
Castle Knight 1 Bookshelf Speakers — Real Wood Cherry, Pair
From a Yorkshire company that spent forty years being known for its cabinets above all else. The cherry veneer is deep-figured real timber, book-matched across the two cabinets so the grain mirrors when they are set up together, then sealed and waxed by hand over more than five days. Underneath is an honest two-way bass-reflex with a 130 mm woven natural-fibre bass/mid driver and five-way binding posts. Very Good condition.
