A Tour De Force
Close your eyes on our largest RTiA bookshelf speaker and you’ll believe you’re listening to floorstanding speakers. It features a 6 1/2-inch Dynamic Balance® woofer, 1-inch Dynamic Balance dome tweeter and 150 Watt power handling, Mark Marcantonio from Affordable Audio comments “The timbre and spacious presentation was dead on,” and “The clarity of all vocals (no nasal or fuzziness) makes for an easy and non-fatiguing listening experience.” In summary, the RTiA3 is perfect for the most demanding home theater system and the most discerning stereo listener.
The proprietary curved, 6-layer DAHLI enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonances. RTiA3 cabinets are designed for clean, accurate sound.
Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
Polk’s proprietary, patented Dynamic Balance technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.
The RTiA Cascade Tapered Crossover eliminates the comb filtering and beaming, common to multi-driver speakers, which degrades the quality of the audio and collapses the soundstage.
Beautiful curved furniture-grade hardwood veneer cabinet finishes, with sleek trim accents in black or cherry.
Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference.
PowerPort® bass venting is our patented design for smoothly transitioning the air flow from the port into your listening area, eliminating turbulence and distortion, for bigger, more musical, deep bass impact.
Our patented Acoustic Resonance Control® (ARC) port technology tunes out the internal cabinet resonances resulting in natural uncolored midrange reproduction.
All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options.
All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.

"Right out of the box, the RTi A3 impressed me with its fit and finish...For years, I'd thought that a good minimonitor speaker with a 5.25" woofer was all I'd ever need to fully enjoy music in my small listening room. But after hearing the Polk RTi A3, with its 6.5" woofer and Power Port Plus and all that other stuff, I'm not sure I can go back."

"...the A3 speakers now delivered full-range stereo music with impressively uncolored mids on both male and female vocals. The sound was still just on the warm side, but treble was ample and generally well balanced, and the midbass rich but not boomy...
...the A3 pair's smoothness on vocals, brass, strings - pretty much everything - was very satisfying. They also produced surprising bottom end."

"I started with Trisha Yearwood’s Songbook cd. My first impression of the RTiA3’s, is that of an airy speaker, very light and nimble. Yearwood’s vocals came out smooth, the upper treble was quite pleasant yet still full.
... Matching up a pair with a receiver will yield quite favorable results without having to empty the wallet for mega-wattage home theater receiver. I found that 60 wpc made for a fine pairing..."

"From faithful bass reproduction to crisp, clean highs, sound is excellent. The real wood cabinets are handsome and should go with just about any decor. All in all an excellent offering from Polk Audio."
