The Polk Audio RTi A7 are crisp and detailed 3-way floorstanding tower speakers featuring dual 178 mm bass drivers, a 165 mm midrange and a 25 mm dome tweeter. In a medium-sized room they produce generous bass with plenty of presence.
These pre-owned speakers are in good condition in cherry, with no manual and no original packaging.
Aimed at audio enthusiasts looking for substantial floorstanding performance at a competitive price, the RTi A7 combine soundtrack-scale low frequencies with the midrange clarity needed for both music and film.

Why Choose the Polk Audio RTi A7 Floorstanding Speakers?
The RTi A7 are built for listeners who want tower-speaker scale without giving up midrange definition.
• Generous Bass Output: Dual 178 mm drivers and dual ports move air with authority.
• Dedicated Midrange: Separate 165 mm driver keeps voices clear when the woofers are working hard.
• Wide Soundstage: Cascade Tapered crossover helps the image open beyond the cabinets.
• Solid Cabinet Work: DAHLI enclosure reduces the boxy colouration common in large towers.
• Flexible Power Range: 90 dB sensitivity and 8 Ω nominal load suit many mid-powered amplifiers.
Audition the Polk Audio RTi A7 at our Lane Cove showroom to hear their combination of bass weight and midrange detail.
Crossing over at 125 Hz and 2.7 kHz, the RTi A7 assign bass, midrange and treble to dedicated drivers.
Frequency response quoted from 20 Hz to 27 kHz and 300 W power handling give them the bandwidth and headroom for large-scale music and home theatre use in a medium room.
At 1073 × 226 × 454 mm and 25 kg each, these are proper floorstanders rather than slim lifestyle towers.
That cabinet volume, plus front- and rear-firing ports, is why the Polk Audio RTi A7 can sound so full-bodied when given a capable amplifier and a little room to breathe.

Condition unknown makes this harder to pin down, but A$1,200 is clearly ambitious for a used pair of RTi A7s. Typical second-hand pricing for this model has been landing much closer to the A$400–A$700 band depending on condition and market, so this needs to be in unusually clean shape with extras to justify the ask.
That said, these are well-liked for big, lively, easy-to-drive sound with strong bass and scale, so a good pair can still be a satisfying buy if you want roomy, energetic towers. At this price, I’d want original grilles, spikes, packaging, and proof they’ve been well cared for; otherwise, there’s little upside versus waiting for a better-priced set.
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.
