We Have just traded in a pair of these legendary Polk rtia9 speakers, the predecessor to the Reserve R700 series these were such a much loved model that they returned from supersession three times due to dealer and customer demand. It wasnt until the R700's arrived that these could finally be updated and discontinued. Your chance to own a pair of these classics without the price tag.
One grill has two missing tabs, but they do come with aftermarket isolation feet as pictured.
We did not get boxes for these so really pick up from Murarrie is the only option.
We do not offer free shipping on pre loved equipment.
Notable mainly as a big, full-range floorstander with a reputation for scale and easy room-filling sound. At A$1,250, it sits above the listed used-market 75th percentile of A$1,150, so this is ambitious rather than a fair-ask buy.
That said, the RTi A9 is well liked for its dynamic presentation, strong bass weight, and lively top end, which makes it a fun choice for movies and rock if you have the space and power to drive it properly. If the cabinets are clean, drivers original, and the listing includes grilles/spikes, there’s real upside in a known performer that’s getting harder to find in tidy condition. I’d only bite at this number if the condition is exceptional or it comes with extras.
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.
