Polk Audio SDA 1A – Vintage Hi-Fi Speakers (Made in USA) I’m selling a pair of Polk Audio SDA 1A (Stereo Dimensional Array) loudspeakers, true hi-fi classics from the mid-1980s, proudly Made in the U.S.A. This rare and sought-after model features Polk’s patented SDA technology, which creates an exceptionally wide and immersive soundstage by eliminating interaural crosstalk. Even today, these speakers are highly regarded by audiophiles.
📌 Key Specifications: Production years: 1985–1986 Dimensions (each): 44″ H × 16″ W × 11″ D (approx. 112 × 40 × 28 cm) Weight: ~75–85 lbs each (≈35–39 kg) Frequency response: 15 Hz – 26 kHz Nominal impedance: 4 Ω (DC resistance ~3.4 Ω) Tweeter: SL2000 Comes with the original packaging – extremely hard to find! 🔊 Condition: Like new never used Both speakers are in very good condition for their age. Some normal cosmetic wear consistent with vintage gear, but overall very well preserved.
📍 Local pickup preferred due to size and weight. Shipping possible at buyer’s expense and risk. Perfect for collectors and vintage hi-fi enthusiasts looking for the spacious, powerful, and highly engaging sound these SDA speakers are famous for.
