Pair of Polk Audio RTI70 towers. Speakers are in excellent condition, cabinets show slight marks but no damage. Overall they are in great condition. The grills are both in excellent condition with no tears.
Should you jump on it at US$175, or wait? Against your comps, it lands a touch above the US$165 median and well below the US$248 75th percentile, so this reads as fair-to-good value, not a steal and not ambitious.
What makes it appealing is the combination of a respected older Polk tower design and the excellent stated condition, which matters a lot for speakers this age. These were built to play confidently with real scale and weight, so a clean pair can be a very satisfying buy for someone wanting full-range sound without moving into modern boutique pricing. If the cabinets, drivers, and grilles are all original and tidy, this is the kind of listing that rewards a quick, local pickup.
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.
