Duntech Opal Floorstanding Loudspeakers Selling a pair of Duntech Opals. Excellent Condition. Part of the Gemstone Series, proudly Made in Australia. Original owner, purchased new directly from Duntech in South Australia back in 2001 - 2002. Includes original shipping boxes with styrofoam, manual and brochure. I have all 8 original gold-plated binding straps for single-wiring, as well as all original floor spikes: nothing missing here! These loudspeakers have been very carefully looked after, with the cabinets’ beautiful real-wood Australian Jarrah veneers regularly polished with Marveer f
At AUD 1,200, these Duntech Opals undercut the typical used market by a wide margin—our recent comps show a median of AUD 3,218 for similar vintage towers, with the 25th percentile at AUD 2,836 and 75th at AUD 5,679. Compared to entry-level modern floorstanders like basic KEF Q-series you could snag new around AUD 2,000, this looks like a potential steal if they're intact, though such aggressive pricing often flags cosmetic wear, repairs, or unknowns.
Buyers, inspect the Sovereign drive units closely—Duntech's paper cones are prone to edge degradation after 30+ years, and foam surrounds may need recapping. Verify original crossovers haven't drifted (test frequency response), and confirm both grilles, spikes, and serial-matched pairs are included; missing bits can add AUD 500+ to restore.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Duntech Audio traces its origins to John Dunlavy, who founded the company in Dallas, Texas in the late 1970s as Audio Standards before it became Duntech Audio. In 1981, the entire operation relocated to Adelaide, South Australia, where it established itself as a privately held, wholly Australian-owned corporation. The company's early history included expertise in antenna systems dating back to 1963, knowledge that informed its transition into high-end loudspeaker design. The company's first wall-mounted loudspeaker entered production in 1982, claimed as the world's first full-range, audiophile-quality design of its kind.
Duntech specializes exclusively in loudspeakers, positioning itself firmly in the ultra-premium segment. The brand gained international recognition with its flagship Sovereign 2001 loudspeaker, introduced in 1986 and retailing at $15,000 per pair. These towering, sealed-box designs became known for their time and phase coherence, earning praise from audio experts for reproduction described as "the closest approximation to the live musical event." The company's design philosophy emphasizes precision engineering and acoustic purity over conventional approaches.
Today, Duntech occupies a niche position as a boutique high-end manufacturer with significant collector and enthusiast appeal. Under current ownership since 2004, the brand has continued producing legacy Sovereign models while developing new designs including the Senator and Princess loudspeaker systems. Duntech maintains its reputation for uncompromising engineering standards and remains respected among discerning audiophiles who prioritize acoustic accuracy and heritage craftsmanship over mass-market accessibility.
