Our Thoughts RADAR AI

At US$100, this Paradigm ADP-100 listing is ambitious compared to the typical used market, where comparable dipole surrounds often sell between US$60 and US$75. New ADP-100s are long discontinued, so there’s no current retail anchor, but the asking price sits well above the median for this model in the current used market.

The ADP-100 is a respected dipole surround that delivers the wide, diffused ambience ideal for 5.1 and 6.1 setups, and it pairs naturally with Paradigm’s Cinema series. If this unit is in original-owner condition with intact grilles and no driver issues, it’s still a solid component for a dedicated home theater, but the price demands pristine condition to justify the premium over the US$60–US$75 norm. At US$100, it’s only a clear buy if the seller includes original accessories or shows exceptional care.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Paradigm

Paradigm Electronics was founded in 1982 in the suburbs of Toronto, Canada, by Scott Bagby, a pioneering loudspeaker designer, and Jerry VanderMarel, a consumer electronics veteran. With input from Jerry's brother Bill, they revolutionized speaker design by integrating scientific acoustics research from the National Research Council of Canada and rigorous listening tests. From humble beginnings, Paradigm rapidly expanded, opening its Paradigm Advanced Research Center in 1993 and earning early accolades like the 1990 Best Price/Value Award, cementing its innovative heritage.

The brand focuses primarily on high-performance loudspeakers, including iconic models like the Atom and Monitor series, alongside premium lines such as Signature. Paradigm controls its entire production process in a massive 225,000-square-foot facility outside Toronto, manufacturing drivers, cabinets, and components in-house for unmatched precision. While best known for freestanding and architectural speakers, it has ventured into electronics through sister brands like Anthem, emphasizing value-driven hi-fi without straying into turntables, DACs, headphones, or cables.

Paradigm holds a strong mid-to-high-end position in the global market, renowned for delivering audiophile-grade sound at accessible prices. A bestseller across six continents, it commands significant shares in freestanding (No. 6) and architectural speakers among top integrators. Repurchased by founder Scott Bagby in 2019, Paradigm upholds its commitment to the "Paradigm Sound"—transparent, dynamic audio that punches above its weight, appealing to discerning buyers seeking Canadian craftsmanship over boutique exclusivity.
