Polk Reference RT55i speakers. They sound great. They have a few minor blemishes but are in really good shape. The tweeters were recently replaced with factory OEM parts.
At US$285, this sits above your database median of US$183 and well above the 25th percentile at US$115, but still below the 75th percentile of US$341. That makes it a somewhat ambitious but still defensible asking price rather than a bargain; I’d call it fair if the cabinets are clean and the drivers are healthy, but not a standout deal on price alone.
The RT55i is a well-liked Polk vintage monitor: smooth, easy-to-listen-to sound, solid midrange presence, and enough scale to work well for everyday stereo use. If these are original, unmolested, and the surrounds and tweeters are intact, there’s real upside for a buyer who wants a classic all-rounder without chasing collector pricing; I’d mainly want confirmation of driver condition, grille/cabinet integrity, and whether the pair is complete before paying near the top of the recent range.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Polk Audio emerged in 1972 from the inventive spirit of three Johns Hopkins University graduates—Matthew Polk, a physics major, George Klopfer, and Sandy Gross—in Baltimore, Maryland. What began as a modest venture building public address systems for local events evolved into a dedicated speaker company after an initial contract fell through, leaving the founders to sell their redesigned cabinets directly. Fueled by passion for music and hi-fi innovation, they secured Small Business Administration loans, relocated operations, and rapidly scaled production, hitting $1 million in revenue by 1976 and earning a spot on Inc. magazine's list of America's fastest-growing private companies.
The brand has long focused on loudspeakers as its cornerstone, pioneering models like the Monitor 7 series for balanced dynamics, deep bass, and high-volume performance that bridged European refinement with American power. Polk expanded into automotive audio through partnerships like MOMO in 1999, while maintaining a core lineup of home speakers, including innovative SDA technology for enhanced soundstaging. Though not delving into amplifiers, turntables, DACs, headphones, or cables, their emphasis remains on reliable, high-fidelity transducers engineered for generations-spanning accuracy.
Polk Audio holds a solid mid-tier position in the hi-fi market, prized by enthusiasts for value-driven performance sold through specialty stereo shops and big-box retailers like Best Buy. Once publicly traded on NASDAQ in 1986 before going private in 1999, the brand now operates under Sound United, upholding its legacy of accessible excellence without chasing ultra-high-end exclusivity or vintage obscurity.
