At USD80 for a pair, this is a solid bargain on the used RTi28s—right in line with recent Reverb listings at USD79.99 in very good shape, though fair market typically spans USD80-230 depending on condition and shipping. These mid-2000s Polks punch above their size with that 5.25" driver and Power Port bass down to 59Hz, but they're no steal if cosmetics or drivers show wear.
Before biting, verify the surrounds on those mids aren't degraded—common foam rot on older RTi models leads to muddy sound—and check for intact original grilles plus both sets of 5-way binding posts. Test with pink noise to confirm impedance holds steady at 8 ohms without distortion.
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.
