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.
PSB Alpha A/V Shielded Bookshelf Speakers — 6.5″ Woofer, Canada
The final 6.5-inch version of the speaker that made PSB's name — the 1998 Alpha A/V, with the upgraded tweeter, crossover and banana-plug terminals, and magnetic shielding so it can sit right beside a screen. Ninety decibels sensitive, so a modest receiver drives them well. Black ash, graded Very Good, bench-tested here. Pair.
