Vintage Bozak B302A Speakers – Excellent
$500 · West Linn (Portland)
Bozak is an American loudspeaker legend, and the B302A exemplifies their philosophy: a 12″ B-199A woofer, B-209A midrange, and an array of B-200y tweeters carefully arrayed for wide, even dispersion and a notably natural tonal balance. Rudy Bozak’s speakers were hand-built and highly regarded by studio engineers and audiophiles alike. These do admittedly look a bit more like end tables than high end speakers, but they have a good reputation.
Pair of Martin Logan esl x speakers 1200obo
$1,200 · Boise
Martin Logan’s ElectroMotion ESL X is a hybrid electrostatic speaker, pairing a large curved electrostatic panel (for midrange and treble) with a conventional dynamic woofer for the bass frequencies below 500 Hz. The result is the transparency, speed, and pin-point imaging electrostatics are famous for, without the full-range limitations of pure electrostats. At $1,200 OBO — roughly a third of its original retail price — this is a compelling entry point into planar sound. I know a friend with a pair of these and they’re incredible.
Polk Audio SDA1 Speakers
$550 · Boise
The Polk SDA1 was part of Polk’s revolutionary “Stereo Dimensional Array” lineup, which used a proprietary interconnect cable to feed a crosstalk-cancellation network between the speakers — effectively removing each ear’s ability to hear the opposite channel and producing dramatic, lifelike staging. The SDA1 is the entry-level model in this esteemed series, and this pair comes complete with the essential 20-foot interconnect cable at $550 OBO. Vintage Polk have a great reputation in a way modern Polk really doesn’t, these could be well worth it.
Polk Audio – Complete setup
$2,999 · Richland, WA (Tri-Cities)
A rare chance to acquire a complete Polk Audio SDA system from the brand’s 1985–91 golden era, headlined by the flagship SDA-SRS 2.3 towers alongside rear speakers, center channel, and powered subwoofer. The SDA-SRS 2.3’s proprietary crosstalk-cancellation technology is what hardcore Polk fans still consider the pinnacle of mass-market home audio engineering — this turnkey system at $2,999 is priced fairly for what’s included.
(Make Offer) Polk Audio Monitor 10B Speakers – Pristine Condition
$390 · Bellevue (Seattle)
Lots of Polk today. The Polk Audio Monitor 10B is a classic early-1980s three-way floor-stander that helped define Polk’s early reputation for high-value audiophile performance. This pair is described as pristine and 100% original, with close serial numbers and healthy butyl rubber surrounds — no foam rot — which is the critical detail with speakers of this era. Hard to find in unrestored, original condition like this.
Pair of Vintage Walnut Sansui SP-2000 4-way full range, 6-speaker
$225 · Bellingham
The Sansui SP-2000 is a remarkable 1969 four-way, six-driver floor-stander from Japan, housing a 12″ woofer, dual midranges, dual horn tweeters, and a super tweeter in a handsome walnut cabinet — plus rear-panel room equalization switches that were unusual for the era. At 45 lbs per cabinet and full of vintage Japanese engineering ambition, the SP-2000 was clearly built to impress, and at $225 it still does. Now, Sansui speakers were built for people who wanted the aesthetic first, so they’re not the absolute best sounding vintage speakers out there but paired with a vintage system they do sound great. (I’ve personally owned SP-2500s and SP-3500s at different times.)
Pair of Vintage Walnut SP-30 bookshelf speakers
$200 · Bellingham
The Sansui SP-30, also from 1969, is the compact sibling to the SP-2000: a 2-way bookshelf speaker with a 6.5″ woofer and a distinctive 2″ horn tweeter in the same walnut finish. These examples are in nearly mint condition with original box — a rarity for a 55-year-old speaker — and the seller notes they pair naturally with their SP-2000 listing, offering a way to build a period-correct Sansui system.
Unique Design Acoustics PS-10 Speakers
$240 · Sequim (Olympic)
The Unique Design Acoustics PS-10 is genuinely one-of-a-kind: a 1990 “point source” three-way with a 10″ woofer firing downward through a 1″ slot at the base, a 5.25″ midrange, and a tweeter with an adjustable brightness control, all in a rubber-faced, mirror-imaged pair designed to minimize diffraction. The seller’s description matches what little documentation exists online — these were a short-production curiosity that audiophile forums occasionally surface as a hidden gem.
Monsoon MM 700 Planar Desktop Speakers, Parts Only
$80 · Sherwood (Portland)
I don’t generally highlight computer speakers in this feature, but these are an exception. Monsoon’s flat-panel planar satellite speakers from the early 2000s are distinct from most low-end computer sets. This MM-700 2.1 set has one damaged satellite and is listed for parts, but the subwoofer and remaining hardware are functional; for someone with the right repair skills, this is a worthwhile restoration project at $80.
Definitive Technology Mythos Hi End 5 speakers set
$260 · Lynnwood (Seattle)
Definitive Technology’s Mythos series was the brand’s flagship lifestyle line, with each Mythos Two tower housing a built-in powered bass module and bipolar driver arrays that send sound both forward and backward for a spacious, room-filling presentation. This complete five-speaker set — four Mythos Two towers plus the Mythos Three center channel — in great working condition at $260 is strong value for a dedicated home theater or two-channel room.
