Polk Audio RT55 Bookshelf Speakers – Real Wood, 200W
Description
Polk Audio’s RT55 is a classic large bookshelf / standmount design from the RT series, combining real wood veneer cabinetry with dual 6.5″ Dynamic Balance drivers and a 1″ trilaminate dome tweeter for powerful, full-range sound from a compact footprint. This pair is in very good condition, finished in black real wood veneer, and features freshly re-clothed grilles that give them a clean, updated look while preserving their original style.
Each RT55 uses two 6.5″ (165 mm) Dynamic Balance mid/bass drivers to deliver impressive bass weight and punch for a bookshelf design, supported by a carefully tuned bass-reflex enclosure with front and rear porting to control resonance and extension. The 1″ (25 mm) Dynamic Balance trilaminate dome tweeter provides smooth, extended highs with good detail and a wide listening window, making these speakers equally at home with music and home theater use.
With an overall frequency response rated from 35 Hz to 26 kHz (‑3 dB from 47 Hz to 25 kHz), the RT55 offers genuine full-range performance for small to medium rooms, often making a separate subwoofer optional for music. Sensitivity is a healthy 91 dB (1 W / 1 m) and nominal impedance is 8 ohms, so they’re easy to drive yet capable of handling up to 200 watts of clean amplifier power. Dual sets of 5‑way binding posts on the rear allow for bi-wiring or bi-amping if desired.
Cosmetic condition is very good overall. The real wood veneer cabinets show only light signs of use, with no major chips or deep scratches, and the new grille cloth gives the front view a fresh, tidy appearance. All drivers, ports, and binding posts are in good shape, and the pair has been tested to confirm proper operation across the full frequency range.

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.

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.

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.
