Potent bookshelf speakers

Thoughtful cabinet design

Cabinet cross-section

The asymmetric cabinet helps fight vibration for clearer sound.

The RTi A1's newly designed asymmetric cabinets help them 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 A1s do a great job with stereo music on their own, or 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 A1s work perfectly as surrounds in combination with RTi tower front speakers.

Recommended center channel speaker: Polk CSi A4.
Recommended surround speakers: Polk RTi A1.

    Driver Technology
    Enclosure Design
    Mounting Options

    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 5-1/4" 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 50Hz-27kHz and the -3dB frequency response is 60-26kHz.

    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.


    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.

    Q & A

    Customer Q&A

    Crutchfield asked  
    Why did you buy this?

    awesome!!!! especially for the price!!! [ Robbie  Sep 25, 2018 ]
    Although I am not 100% sure how I feel about the grey accents, these are a gift and I have a feeling my nephew will think they add to their coolness factor. My first real speakers were Polk and I have respect for the brand. The price fit where I wanted. The option to bi-amp is nice, although I know there are conflicting schools of thought about the efficacy of it. Dimensions-wise I think they will be a perfect fit, and they should last for many years. [ JUSTIN  Jul 14, 2018 ]
    Reviews [ G  Jun 08, 2018 ]
    after having spent literally weeks working on what I could afford for my music this is where I am. I believe I'm in a good place, good speakers, good company, got no complaints. thanks Crutchfield, we shall see. [ steve  May 22, 2018 ]
    Matches the sound profile and class as my sub and center. [ SEAN  May 15, 2018 ]
    I have a number of products from Polk. The sound quality is very nice. Crisp clear vocals is the norm. The subs I've used bring a warm low end that immerses me in quality sound. [ Alton  May 03, 2018 ]
    This is my second purchase for the Polk RTIA1. First one sounded great and price was in my ballpark. [ Peter  Mar 20, 2018 ]
    represented a great value and Dee (advisor) helped narrow down my choice between S15 and RTiA1 [ Y  Feb 21, 2018 ]
    Price, size and customer reviews. [ Peter  Feb 14, 2018 ]
    I needed a pair of front speakers to go with my Polk surround sound system, and these were video-shielded and on a good deal [ Torin  Jan 13, 2018 ]
    I have other Polk speakers that I really like. Plus, the price was too good to pass up for this quality of speaker. [ Abdon  Jan 12, 2018 ]
    I wanted a good pair of non - ported bookshelf speakers that could fit in my entertainment center. The Polk Audio RTi A1 reviews and size fit the bill perfectly. [ Randy  Jan 03, 2018 ]
    Do not think you can go wrong when selecting a speaker from Polk. I was looking for a rich full sound, from a smallish speaker, I am pretty sure this will fit the bill. [ Thomas  Dec 30, 2017 ]
    Recommended by consultant on phone [ Steve  Dec 25, 2017 ]
    5 star rated, polymer cone woofers [ Diane  Dec 23, 2017 ]
    These speakers will make a nice addition to my Infinity speakers and Polk sub. The Polk brand and high reviews made them an easy choice. Plus $130 off! [ Paul  Dec 18, 2017 ]
    I have owned Polk Audio speakers for over 30 years. Quality, craftsmanship, sound etc., very tough to beat for the price. [ Richard  Dec 15, 2017 ]
    Size, look and recommendation from sales associate, Colt. [ Jeffrey  Nov 26, 2017 ]
    I needed a new pair of speakers for a small room. The reviews looked great and Sam was very helpful in making me aware of the options of closed box, open box and scratched or dented. Very positive guy to work with. [ Randolph  Nov 19, 2017 ]
    Recommended paring with Center channel speaker Polk Audio CSi A4 [ Edmund  Nov 15, 2017 ]
    Great reviews. I previously owned Polk speakers and would not want anything but Polk Speakers. [ Barbara  Sep 23, 2017 ]
    To complete my set. Love my others. [ John  Sep 21, 2017 ]
    Been wanting this speaker for a long time now! I'm purchasing while the sale price lasts. [ Maria  Sep 20, 2017 ]
    Replacing some satellite speakers, I have other Polk RTi speakers excellent built and sound quality. [ PPMC MFG,  Jan 18, 2017 ]
    recommended by advisor [ MARY E  Nov 28, 2016 ]
    Estimated best value for a shielded L/R speaker placement. [ Russ  Oct 27, 2016 ]
    Great balance between size and performance [ JEFFREY  Jun 29, 2016 ]
    Good reviews and attractive [ Peter  Aug 25, 2018 ]
    l have been looking for an affordable bookshelf replacement for my older tower speakers that just aren't what they used to be. After some research decided to try these Polk Audio bookshelf speakers. Polk's reputation for quality, the attractive design, specs, bi-amp option,keyhole slot for hanging won me over. [ Rodney  Aug 12, 2018 ]
    Excellent price, good experience with Polk Audio in the past, good experience with Crutchfield each time. [ James F.  Apr 29, 2018 ]
    I would've liked to listen to these before buying, but that's hard to do these days. One store with a good listening setup had Polk S15s that sounded acceptable, but of course these may be very different sounding. I was able to quickly rule out Klipsch, so that helped a little. I've always liked the sound of Polk speakers in general, and I have a pair in my car for 5 years which are great. The Cherry also look the nicest in the price range, which my wife likes a lot. [ THOMAS  Mar 14, 2018 ]
    I chose these speakers for Polk Audio's reputation for performance,quality,design,and a high level of excellence; they look great too. My experience with Crutchfield has always exceeded my expectations and I highly recommend doing business here. [ Lynn  Mar 13, 2018 ]
    Reviews, experience with Polk Audio, sale price, and lastly appearance. [ Devan  Mar 11, 2018 ]
    great price, good product. Because it will suffice for my needs, and it was almost 50% off - that was primary factor. Even at the 199 discount I was going to pass. I am in that small demographic that loves a bargain that is only cosmetically flawed. Keep selling us the scratch n dent suff! [ steven  Mar 10, 2018 ]
    Matched to my existing speakers...using as rear surround speakers [ Jeff  Mar 04, 2018 ]
    I chose these speakers to compliment the RTiA9's that I bought. [ Albert  Feb 13, 2018 ]
    I needed a high efficiency speaker with great performance to use with a vintage Marantz 2230 Stereo Receiver. I currently run a Marantz NR 1605 through a set of Polk TSi 100 and PSW 110, so based on the performance of my current speakers, I figured I can't go wrong with another set of Polk Audio speakers. Based on the specs of the RTiA1 I believe they will compliment my Marantz 2230. The design and Cherry finish has always been a favorite, seen the discounted price and I was happy! [ fred  Feb 12, 2018 ]
    Experience and size. I own larger Polk speakers on another 5.1 system. [ Augustus  Feb 10, 2018 ]
    I needed small-sized speakers with good sound (for a small room) for the receiver I just purchased. The specs appear to indicate that this will be just right. [ Franz  Dec 09, 2017 ]

    I have Polk 3.1 tv sound bar w/ 6.5 inch woofer ---- so wanted smaller speakers in bookcase unit (5.5 inch) [ Dieter  Nov 26, 2017 ]
    I have always liked the sound and build quality of polk speakers [ Michael  Nov 19, 2017 ]
    I have various Polk speakers from a classic pair of SDA's to subwoofers to outdoor speakers. I needed some reasonably small bookshelf speakers for my home office. I added a small Polk sub. Have always liked the sound of Polk tweeters. [ J  Nov 19, 2017 ]
    I have owned a pair of Polk speakers since 1975. They are great. [ Kris  Oct 20, 2017 ]

    Price and looks [ SAMUEL  Oct 14, 2017 ]
    So impressed with past POLK speaker purchases because of it's great VALUE (most bang for the buck) and dead neutral SOUND quality! [ Bradford  Sep 22, 2017 ]
    Already have RTi's in my set up. Getting 2 more to complete my 7.1 system. Have been using them for the past 8 years. Absolutely love the sound of look of the speakers. [ Kevin  Sep 21, 2017 ]
    Great price, and well reviewed for sound quality. Small enough for my bedroom, and easily wall mountable. [ Robert  Sep 17, 2017 ]
    We've had a pair of larger Polk Audio bookshelf speakers for 16 years. GREAT sound and still going strong. I wanted speakers for our back office, so chose these. Nice sound for the size. [ Stephen  Sep 23, 2016 ]

    3 questions already asked

    If the subwoofer has a line input (RCA or Mini) then you should be able to connect it to the receiver. Either directly using the subwoofer level output and line-in or with an adapter from the RCA level output of the receiver to the mini jack in on the subwoofer (again depending on the input). If the subwoofer does not have a line input then it will not work with the receiver. [ Jeff  Mar 19, 2015 ]  Staff
    I feel it's very much an awesome value. I power these speakers (wall mounted) w onkyo tx-8050. My space is a 900 square foot bottle shop. We run internet radio and play vinyl daily. RTi A1 's sound awesome bass without a sub. For our purposes, perfect. Sometimes we have upwards of 40 ppl in that small space and they still deliver. hope this helps. PC [ PHILLIP  Sep 09, 2014 ]
    Is RMS or "root mean (average) square value. The rule is that Max or Peak values are are clearly stated in any equipment specs. There is One Peak value not a range of Peak Values. The RTi's are very efficient speakers so they can work well with a low power amp as low a 20 watt in the connected channel. They can work in a high power channel up to 125 watts as well. 125 is the maximum RMS watts recommended for the speakers. It seems these speakers were well tested at different power supplies for a certain time period. I am using then with a Denon AV-E400 185 Max output watts/channel (90 watts RMS/Channel). Sounds great. If 20 t0 125 were peak values, (there can only be ONE peak value) they could'nt hold 90 watts RMS. Hope this can help. [ ANIBAL  Sep 05, 2014 ]
    I have connected it to my Denon AV Receiver [ brian  Dec 11, 2017 ]
    I love these speakers. I use them in a music room that is 25x25. I added a powered sub for more off a low end punch. They are well built quality multi tome speakers. Crisp, clean. [ john  Dec 11, 2017 ]
