Overview

Our take on the Polk Audio RTi A3

The Polk RTi A3s prove that you don't need big speakers to get good sound. These bookshelf speakers feature Polk's exclusive Dynamic Balance® drivers for smooth accurate response. The woofers and tweeters undergo careful laser testing to help identify and eliminate unwanted resonances that can hinder a speaker's performance.

Thoughtful cabinet design

Cabinet cross-section

The asymmetric cabinet helps fight vibration for clearer sound.

The RTi A3 sports a newly designed asymmetric cabinet that helps deliver rich, clear sound by combating vibration and increasing rigidity. You'll enjoy remarkably clean mids and highs for a well-defined soundstage, along with tight bass. Plus, the cabinet's curved edges give the speaker a polished look, enhanced by a real wood veneer finish.


Great for home theater or stereo music setups

The RTi A3s do a great job with stereo music on their own, but you can team them with a powered subwoofer for even better bass. Or use two pairs as your home theater's front and surround speakers for dynamic, detailed movie sound. For larger rooms, the RTi A3s work perfectly as surrounds in combination with RTi tower front speakers.

Recommended center channel speaker: Polk CSi A6.
Recommended surround speakers: Polk RTi A3.


Got wire?

Most speakers don't include any. Learn about choosing and installing speaker wire at the Crutchfield Learning Center.

I am not an expert on sound systems, but my new Polk Audion RT A3 really are a great treat for music listening. You don't have to turn up the volume their subtle sound is sweet. They are a nice looking set of speakers. I am happy and then some with them.

    Driver Technology

    Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

    Polymer Composite Woofers: Each speaker features a 6-1/2" polymer composite woofer for smooth wide-range response with low distortion. For high performance durability, each woofer uses a butyl rubber surround.

    Silk/Polymer Tweeters: Each speaker has a 1" silk/polymer dome tweeter that provides clear, detailed highs. Each tweeter features mylar bypass capacitors in the crossovers to extend high frequency response and improve detail and transparency. Each tweeter features low viscosity ferro-fluid cooling with a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.

    Frequency Response: The overall frequency response is 40Hz-27kHz and the -3dB frequency response is 50-26kHz.

    Enclosure Design

    Damped Asymmetric Hex Laminate (DAHLI) Cabinet Design: All-MDF construction with massive asymmetric cabinet bracing ensures a resonance-free enclosure for accurate sound. The asymmetric design is made from a 6-layer laminate with 5 viscous layers to create the optimal shear damping (OSD) system. The elegant styling aside, curved cabinets not only result in a stronger, more rigid and acoustically inert enclosure, but the curved walls also produce less audible coloration from panel resonances.

    Power Port Venting System: Each speaker has a rear-firing Power Port venting system built into its back plate for precise deep bass response. This venting system allows air velocity to slow gradually, vastly reducing air turbulence, and delivering greater bass efficiency than conventional ports.

    Acoustic Resonance Control (ARC): Internal cabinet resonance can impart a "thick" character to voices. Polk's patented Acoustic Resonance Control port system overcomes this problem. In addition to the Power Port venting system, each speaker has a front-firing port that is tuned to suppress the internal cabinet resonance, resulting in smooth, natural midrange reproduction.

    Anti-Diffraction Grilles: The floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging.

    Connections

    Dual 5-Way Binding Posts: Each speaker has two sets of gold-plated 5-way binding posts connected by gold-plated jumpers. Using the dual 5-way binding posts, you can bi-amp or bi-wire the speakers.

    Mounting Options

    Wall Mounting: The Power Port back plate on each speaker has a keyhole slot, allowing the speaker to be mounted on the wall using the supplied 2-1/2" wood screws.

    Magnetically Shielded: The speakers are magnetically shielded, allowing you to place them near your television without distorting the picture.

    Crutchfield asked  
    Why did you buy this?

    Value [ Carl  Jun 13, 2017 ]
    After watching many online videos comparing several bookshelf speakers, the Polk Audio RTi A3 seem to be what I need for my living room. [ Juan P.  May 30, 2017 ]
    I chose these RTi A3 because it was time for me to upgrade from my Polk M1 which has been with me for the last 17 years. Since i also bought the new floor standing speakers i figure these RTi A3 would work perfect as well. [ Judy  May 22, 2016 ]
    I have a set of these speakers already, that I've had for about a year now. Great speakers. [ RICHARD  May 01, 2016 ]
    These speakers had the features that I wanted and the reviews were good. [ Steve  Feb 21, 2016 ]
    It was love at first sight for the RTi A series. The Cherry finish was irresistable. I had been enjoying the RTi6 (BLK) for several years and just had to upgrade based on the very positive reviews for both the RTi A3 and A1. I actually started with the RTi A1 and just could not warm up the sound. I then auditioned the RTi A3 and was wowed initially, but after some very serious A/B, the RTi6 won out. Sadly, I retuned the A3 with minor negatives, just personal preference for the RTi6. [ LOWERY  Mar 19, 2017 ]
    Gift for musically talented son. [ John  Mar 05, 2017 ]
    Fantastic sound!! Great balance between sound and physical footprint. These are smaller speakers that have a nice BIG sound! [ Christopher  Jan 18, 2017 ]
    Based on my budget, and discussion with a rep at Crutchfield, they seem to be the best speakers for the money. [ Aaron  Sep 12, 2016 ]
    High quality, good price, great customer service interaction with Lucy. Lucy's Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=119 [ jakie  Aug 13, 2016 ]
    Recently bought the Polk matching center channel speaker and am loving it, so decided to get these for my surround and back channels.. [ Jackie  Aug 08, 2016 ]
    View the review, excellent Base performance and power efficiency for the price. Can compete with speaker of $1000.00. They sound really great. [ Juan  Aug 03, 2016 ]
    Have always been satisfied with Polk Audio Speakers . Excellent value. [ David  Jul 30, 2016 ]
    my son did the research and told me to buy the best. [ Geoffrey  May 23, 2016 ]
    To match my front and center speakers from the same line. [ FREDRIC C  May 20, 2016 ]
    I bought these as a wedding present, I have a pair of them myself and they are great speakers. [ LINDSEY CLYDE  Mar 25, 2016 ]
    Perfect compliment to my Polk Audio Center and Floor standing speakers in Cherry - These will be L/R Rear channels for a 7.1 Surround set up [ Gregory  Mar 21, 2016 ]
    These were bought for a room that has all four walls full of books on shelves. They fit the shelves (barely), sound very good (paired with a scratch and dent Polk subwoofer), and look really nice too. [ THOMAS R  Mar 13, 2016 ]
    It was a mistake buying these because they have no bass for their size, but the overall sound is clean and accurate. They are better used in surround (which I use mine) because the noises running through this channel are truly amazing to the point of surprising me often. [ Audiolad  Mar 09, 2016 ]
    Price for performance based on ratings and internet reviews. [ Joshua  Feb 04, 2016 ]
    Long-time polk audio fan, but used my last bookshelf sized speakers for TV surround sound. These are a more modern replacement. Not the highest quality Polk, but more than good enough for a living room system. Enjoys excellent reviews. [ David E.  Dec 19, 2015 ]
    Surround speakers to match my rti towers. [ Christopher  Dec 17, 2015 ]

    2 questions already asked

    I have 2 pair of these using 2 Denon receivers. different rooms one 90 watts, one 95 watts per channel. great sound! [ RICHARD  Jun 22, 2016 ]
    One hundred watts per channel and they sound great. I had them originally connect to a Yamaha amp that put out about 30 watts per channel in my living room (this was temporary) and they sounded fine at low volume. But, on my new Denon receiver, they seem happier and sound really good. Probably could take 120 with ease. [ John  Jun 21, 2016 ]
    I have a Marantz SR7009 125w. They really could handle them. [ ANTONIO A  Jun 21, 2016 ]
    95 amps [ JAMES  Jun 21, 2016 ]
    Connected to Denon 3311c 125Watts per. I re-allocated my in ceiling Front for Height and bought these to use as Front speakers. Mixed with surround and surround back in wall speakers (all Polk) sounds pretty good when the right content is playing. [ THOMAS C  Jun 21, 2016 ]
    I am powering the Polk RTi A3 with a Yamaha RX-S600 which has 55 watts per channel at 8 ohms. I have no complaints [ Bill  Jun 21, 2016 ]
    This will depend largely on the room and system the speakers will be used in. Contact an Advisor by phone or chat for help choosing the best components for your system. [ Jeff  Nov 24, 2013 ]  Staff
