A recurring feature curating interesting speakers for sale on Craigslist from around the Pacific Northwest. Links to Craigslist postings might go down at any time if they’re sold or pulled from sale. We’re a little lighter this week with only 8 listings, but they’re a pretty interesting set. Take a look:
Polk SDA SRS 3.1 TL Speakers
$750 · Chattaroy (Spokane)
The SDA SRS 3.1 TL represents the final evolution of Polk Audio’s legendary Stereo Dimensional Array technology — an innovative system that uses a dedicated channel of audio sent to the inner edge of each speaker to cancel inter-aural crosstalk, producing a dramatically wider and more enveloping soundstage. This particular pair has received the seller-endorsed upgrades sanctioned by Polk engineering: revised tweeters, crossover improvements, and cabinet reinforcement, making these the most dialed-in version of a speaker that audiophiles regard as uniquely musical and non-fatiguing.
JBL Lancer 77 Speakers
$525 · Portland – Sauvie Island (Portland)
The JBL Lancer 77 is a beloved 1960s two-way floor speaker featuring the original LE10A woofer and LE20-1 tweeter — the same driver family found in far more expensive JBL studio monitors of the era. This pair has been professionally refinished in walnut with all original drivers and crossovers intact and functioning, plus the grilles (which typically show up damaged) described as excellent — a genuine rarity for this model at $525.
Monitor Audio-Silver 300
$1,000 · Walla Walla (Tri-Cities)
Monitor Audio’s Silver 300 is the flagship of the British company’s Silver line, a three-way floorstander with their signature C-CAM (Ceramic-Coated Aluminium/Magnesium) drivers and a dedicated Gold Dome tweeter. This sixth-generation pair is in the premium Rosenut real-wood veneer and has barely been used — the seller claims approximately 30 days of play — making it a rare opportunity to buy near-mint at a significant discount to the $2,000+ retail price.
Marantz Imperial 6-G Speakers
$100 · Ballard (Seattle)
The Marantz Imperial line was the company’s foray into speaker manufacturing in the late 1960s and early 1970s, bearing the Marantz name at a time when that meant uncompromising audio quality. This pair retains its original crossovers but has been modified by a previous owner with GRS 10PF-8 woofers and generic tweeters; the seller notes the tweeters should be replaced, which represents a straightforward restoration opportunity on freshly refinished cabinets for just $100.
Vintage Bose 901 Series 1 Stereo Loudspeakers Rare
$195 · olympia / thurston (Seattle)
The Bose 901 Series 1, introduced in 1968, was a genuinely radical design: nine full-range drivers per cabinet, with eight firing rearward and only one forward, intended to replicate the ratio of direct to reflected sound in a concert hall. These early cloth-surround examples from the early 1970s represent the model at its most collectible and are, I think, the most attractive of the series. You do need the Active Equalizer for best results (read all about that here https://retrovoltage.com/2026/06/12/everything-to-know-about-bose-901-series-i-and-series-ii-active-equalizers-speaker-systems-and-the-800-too/ ) but the Series 1 and 2 use cloth surrounds on the drivers, not foam, so they never need to be refurbished unless they have sustained physical damage. These are only $195, looks like a great deal to me.
Focal Chorus Center Channel Speaker
$300 · Otis Orchards (Spokane)
Focal’s Chorus line brought the French company’s audiophile driver philosophy — including the distinctive inverted-dome tweeter and polyglass mid-bass cone — to a more accessible price point, and the CC700V center channel was a standout performer in that lineup. The Walnut-enclosed cabinet and 91 dB sensitivity make it an easy load for most amplifiers; listed in immaculate condition at $300, it’s a solid deal for anyone building out a Focal-matched system or simply wanting a high-quality center channel.
Verdin church tower clock loudspeaker bell toller
$400 · Indianola (Seattle)
Verdin, founded in 1842 in Cincinnati, is one of the oldest bell and clock manufacturers in North America, and their tower loudspeaker systems were designed to project convincingly across large outdoor spaces — church campaniles, town squares, and university campuses. This 1990s set of four Verdin horn-loaded drivers with the original time-and-bell controller and amplifier was pulled from a working tower clock installation; it’s an extraordinary piece of audio history for $400, and the acoustics of those horns are genuinely impressive. It’s not exactly hi-fi, but these were unusual enough to make the cut for this issue.
Vintage light-up speaker, Mardi-Gras technology
$100 · Corvallis
An intriguing mystery piece from the 1970s: a party speaker with built-in lighting effects (also called a Color Organ) made by Mardi-Gras Technology — a now-obscure manufacturer that produced novelty audio equipment for the disco and lounge market. The seller knows little about its provenance other than it came with the house, and that’s half the appeal — this is the kind of find that rewards an afternoon of research and may turn out to be a genuinely rare survivor of that era’s more playful approach to speaker design. It might be an interesting center channel in a vintage system next to some Sansuis.
