Product Information

A Tour De Force

Close your eyes around Polk's largest RTiA bookshelf speakers and you'll believe you're listening to floorstanding speakers. They feature 6 1/2" Dynamic Balance woofers, 1" Dynamic Balance dome tweeters, and 150W power handling. 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.
  • The two 6 1/2" mid/woofer drivers are housed in their own tuned internal enclosures for increased clarity and life-like detail.
  • 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 Polk's 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 life-time 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.
  • Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference.
  • PowerPort Plus bass venting is Polk's 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.
  • Polk's 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.
  • Dual binding posts allow bi-amp or bi-wire connections, for the ultimate in customized high performance audio.




  • Dimensions (W x H x D): 8.44" x 14.75" x 14"
  • Weight: 16 lbs.
  • Front array driver complement: (1) 6.5" diameter mid/woofer, (1) 1" diameter tweeter
  • Total frequency response: 40Hz - 27kHz
  • Sensitivity (1 watt @ 1 meter): 89dB
  • Lower and upper -3dB limits: 50Hz - 26kHz
  • Tweeter/midrange crossover frequency: 2.8Hz
  • Recommended amplifier power per channel: 20 watts - 150 watts

Wonderful speakers, price and performance winners!
I've had these speakers for almost 2.5 years. They were out in my living room doing 2.1 stereo. I now have a 5.1 Polk Audio home theater with the Yamaha Aventage 2060 (RTI A5 small towers, A1s, and CSI A6).

Needless to say, if they had sounded like Krapola, I would not have opted for the 5.1 Polk RTI package.

For home theater, if you have a 150 to 240 sq foot living room, these make very dynamic and great sounding front speakers. I was also surprised by how good the smaller A1s sound! The A1s sound good, the A3s have a fuller sound and a little better bass extension. The A5s sound best of the three. I was recently blown away by the A5s when I watched chapter 10 of Deepwater Horizon (deepwater horizon, the oil well platform was blown away too!).

The A5s sound fuller and open up with a more powerful amp than the A3s (the Aventage 2060 is a REAL amp with 140 watts per channel). They sound somewhat anemic and lack pounding bass with a less powerful amp. I used a 75 watt Yamaha receiver for them for 6 months and they just sounded OK until I got the Aventage 2060.

The A3s and the A1s should do just fine with a lower level Yamaha AVR that has 80 to 95 watts rms. The A3s have great bass extension down to 50 hertz. They DO benefit from a sub for 2.1 stereo.

These speakers are very easy to place in less than ideal placement settings. I have them now in my 2nd bedroom/home office and one speaker is sitting on a nearly 5 foot tall full size office filing cabinet and the other is on a 2 foot tall end table. I sit about 6 feet from the lower speaker and I am getting surprisingly good results. Thanks to the rear power port that directs the air/sound out sideways in the back of the speaker, they can almost be placed up against the wall and are as easy to place as my old JBL front ported 6", two way Northridge series speakers.

For large bookshelf speakers, they do have a very full and balanced sound to them and do great with all genres of music. They are very smooth as well. I listen to everything from country (Don't Rock the Jukebox!), classic rock, and classical. They don't get distressed at high volumes like my BIC DV62SI budget speakers. You can crank them up and they just smile!

I am very happy with my A3 speakers and heartily recommend them.

The Polk RtiA3
Just got it in today and plugged it (didn't bi amp it yet and wow, so much detail and the bass is outstanding. I was surprised how big it was as well for some it may be a con but for me the sound quality makes up for it. Can't wait to use them as rear surrounds!

Balanced, nearly full range, and detailed sound
I’ve recently upgraded my receiver to a Yamaha R-S 500 (2.1 stereo, 75 Watts RMS), an external DAC for my computer (HiFiMe Sabre 9018 adaptive USB DAC) and these speakers that I bought nearly 6 months ago.

I was using a budget ($110) Sherwood receiver. I added these speakers to the Sherwood and was very surprised at the additional amount of mid-range and mid to upper bass that they provided. The bass is tight and punchy. I can actually feel the bass on my couch from 12 feet away. I did not realize how bright my system was before the upgrade (overemphasis on treble). These speakers are hands down at least two levels above the BIC DV62si bookshelves that I was using with my Sherwood receiver. The Bic speakers are OK for what they are, nice budget speakers – but they should not be a life sentence!

I listen to mainly classical. But I also listen to jazz, pop/rock, Irish Folk (like the Chieftains), etc.. While the Polk RTI A3s are great bookshelves, they were not enough in themselves to solve the other problems in my stereo set-up. The Sherwood lost too much detail when the volume was turned down to medium and to low. That problem was solved by the Yamaha receiver and the HiFiMe Sabre 9018 usb DAC. I use my computer to stream music (Spotify, Classical King FM) and play back CDs and MP3s. The DAC on my old computer was a drag on the music reproduction. My computer was 9 years old with maybe a $2 DAC chip in it. The Sabre DAC has a fantastically good signal to noise ratio (123 db) and after adding it to my new Yamaha, I actually needed to turn down the volume from -25 db to - 38 db. That DAC added more than 50% more power to the Yamaha.

I use these Polks for 2.1 stereo and I also stream movies from Comcast Infinity. These speakers sound fantastic for all types of music and will work great as fronts for 5.1 surround sound movie watching. My apartment is about 750 sq feet and I can get the music uncomfortably too loud in the entire apartment with these bookshelves! My 75 watt receiver can easily drive them. For movies in 2.1 stereo, they are very clear and detailed and are wonderful with dialogue (even whispering is crystal clear!). My living room is about 200 sq feet and these speakers are fine for that size - even up to 350 sq feet or larger they should be fine.

I also have the Polk Audio PSW 10. That Subwoofer is a good choice for an apartment. It provides the lower extension that is missing from the bookshelves. The bookshelves have good mid to upper bass, but one should not expect a 6.5" bass/midrange speaker to perform like a 10 or 12" subwoofer. For example, I listened to Eric Clapton’s Pilgrim CD (from 1998) and alternated turning on and off the subwoofer during playback. This step revealed how low the RTIs will go on their own and what a sub can add to the playback. The RTI A3s sound good on their own, but the sub makes the overall listening experience better. The sub is more needed for movies and pop/rock/country than for classical, but it even helps a little on some of my classical music.

These speakers are large, but still fairly easy to place because of the rear power port. I have them about 4-5 inches off the wall and that does not affect the bass and make it sound boomy or muddled. The power port has a cone helps push the air/sound out sideways instead of straight into the wall.

I highly recommend these speakers for all kinds of music as well as for home theater.

These are wonderful speakers. They give a full rich sound, full of warmth but still excellent detail. I waited a long time to get truly excellent speakers and these are exactly that.

Best Book-shelf Speakers I've Ever Had
These are amazing speakers that have very good highs and lows. They can put out a very high quality sound even at high volumes, without getting disstored at all.
They have a very good, strong bass that you don't need a subwoofer to enjoy music and movies. I mostly listen to electronic and house music, that needs very good speakers to listen to without getting disstored at loud volumes, which these do not get.
The Polk-Audio Rti A3 are hands down the best bookshelf speakers I've ever had, and they give you so much more than their small price that you pay.
I strongley recommend them.

Audiophile quality at a reasonable price
Let me first say that I built some floor standing speakers years ago with Morel tweeters, Peerless HDS mid woofer and twin HiVi 8" woofers as sub range. The top is driven by my Marantz 90/channel, sub by Emotiva 185/channel. They are curved and finished in cherry and to date are the finest speakers I've ever heard.

Now to compare my RTi A3 with my Klipsch 12" subwoofer, and I dare say they give my floor standing a run for their money in sound and looks. Now that's not bad comparing $2500 versus $1200. If anyone is wavering whether to buy these for critical listening, please stop; they are outstanding bookshelf speakers. The bass is tight and deep, but more important the dynamics and transition are as good as any speaker this size at any price. I spent months trialing most of the top bookshelf speakers and couldn't find these. My son convinced me to take a leap of faith and I'm glad I did. I highly recommend these as a bookshelf audiophile speaker.

Wonderful sound...
Initially I was planning on a pair of TSX or the RTI A1 - but then I asked for a demo of the A3 too - and I was impressed the most. The demo system was the same as mine - SC-LX87 (or Elite SC-79 in USA). The sound was incredibly detailed and full-bodied - and so I bought them.

Due to space limitations, wall mounting is my only option. This is an audiophile's nightmare - but then even with these limitations the A3s shine in the Pure Direct mode of SC-LX87 (my preferred mode) for most music. But in those few instance where the bass does get muddy or boomy, I simply switch to the Direct mode to pass it onto the subwoofer. It works brilliantly.

These are worth more than every penny that one pays for them - though it is not much pennies anyway. For all those who want audiophile quality speakers without emptying the bank account - then these are highly recommended.

Time now to get the Polk surrounds.

I have a set of Polk 5jr's and I want to hear the difference 50 years of innovation, technology, and experience has brought to a similar pair of bookshelf speakers. My 5jr's still sound like the day I listened to them in "Absolute Sound" in Ann Arbor, Michigan, the day I purchased them. It's also the day I learned "the rule of diminishing return." Also, I like doing business with World Wide Stereo. I've never been unhappy with a purchase from them.
