Product Details

Polk Audio Black Bookshelf Speakers, Model RTIA1BK

Why settle for vinyl speakers when you can have the warmth and beauty of real wood at the same price, with speakers from the new RTi A Series. They incorporate our latest Dynamic Balance Cone drivers and 1-inch tweeters, with an asymmetric cabinet design that's as beautiful for the way it controls resonance and increases cabinet rigidty as for the way it lends an elegant touch to any decor. The result is classic Polk performance in a design that speaks to today's high-end home décor. True performance art.

Features:

  • Latest generation of Dynamic Balance® polymer composite drivers for smooth wide-range response with low distortion
  • PowerPort® bass venting for superior clean, low distortion bass that you can really feel.PowerPort vastly reduces "chuffing" or "port noise" and provides deeper, more powerful, lower distortion bass than could be realized with conventional ported or sealed designs of comparable size
  • Acoustic Resonance Control (ARC Port) technology for more natural midrange reproduction.
  • 1-inch Silk/Polymer Dome Tweeter delivers smooth response and better detail
  • Magnetic shielding for safe placement near video sources
  • Mylar bypass capacitors in the crossovers extend high frequency response and improve detail and transparency
  • Neodymium magnet, low-viscosity ferro-fluid cooling, and a heat sink on the back of the magnet, create better power handling and reliability
  • Gold-plated 5-way binding post inputs (with wide holes for large-gauge bare wire connections) for the most secure connections and the most versatile wiring applications
  • Butyl rubber surrounds for high performance durability
  • Acoustically inert stamped driver baskets
  • Floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging

All-MDF Construction

  • Cabinet resonance can ruin the sound of an otherwise well-designed speaker. You don't want to hear your speaker cabinets humming along with the music, you want to hear the uncolored sound launched by the drivers and tweeters. We take special pains to make sure that Polk speaker cabinets are resonance-free
    • Damped Asymmetric Hex Laminate Isolation (DAHLI) cabinet design for clean, 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 process was specifically developed for Polk. Their elegant styling aside, creating curved cabinets not only results in a stronger, more rigid and acoustically inert enclosure, but the curved walls also produce less audible coloration from panel resonances
    • All-MDF construction with massive asymmetric cabinet bracing ensures resonance-free enclosures for accurate sound
    • Real Wood finishes at vinyl prices

Unbelievable Sound at an Unbelievable Price

By 

from Las Vegas, NV, United States

Comments about Polk Audio Black Bookshelf Pair Speakers:

I bought these speakers about 5 months ago, and I am truly amazed at how musical they are each and every time I play them. The clarity and beautiful upper and mid-range frequencies allow the listener to hear all the little nuances in a song that only a high quality speaker can deliver. To my ears, they outperform my KEF Q100s, my Paradigm Min Monitors, v7, and my Axiom M3s, v4. I have already gifted the Axioms to my ex-wife and soon will be gifting the KEFs to my daughter and her new husband. I want to emphasize that all of these brands are good speakers with their own unique signature sound, but I have found the Polk Rtia1 speakers to be my favorite. I know that good sound can be subjective to a degree, but I believe that the engineers at Polk have truly hit the "sweet spot" with these speakers and that these speakers would appeal to the majority of listeners. Maybe, bass heads would prefer deeper base, but then, that is the case with most bookshelf speakers. Thank you, Polk, for making a quality product at an affordable price!

Mind Blowing Speakers

By 

from Lawrenceville, GA, United States

Comments about Polk Audio Black Bookshelf Pair Speakers:

I wish I could give these speakers 10 stars; that is how impressed I am with them. I have owned a few so-called good bookshelf speakers including the Elac B5's, Pioneer BS-22's, and Cerwin-Vega. These are the best by far, especially when you consider the price. The B5's were over-hyped and the Pioneers are better for home theater applications than they are for music so I kept them for that purpose. But the Polk Audio RTi A1's are stuck with me for life! Plus, they are so sexy! I have never, ever heard a speaker with a 5.25 inch woofer that performs with the clarity, balance, and controlled bass that these have, and I have had a lot of speaker systems in my time -- big and small. These are mind-blowing "musical instruments" that are posing as speakers. I am in the process of ordering the RTi A3's even as I write this review, and I am going to use my Pioneer CS-R790-K floor speakers as stands for these babies.

best little speaker for the money!

By 

from Colorado Springs

Comments about Polk Audio Black Bookshelf Pair Speakers:

I bought these about 6 mo. ago to replace a pair of Polk RTi4's that I use as my rear speakers. I bought these to pair with the RTiA7's in the front. I thought the i4's were good, but these blow those away. They are relatively similar in features but my system just seemed to come alive when I hooked up the A1's. Couldn't be happier and they fact that I bought them for 1/2 price just made it sweeter! Powering the system is Onkyo TX NR 808 (Bi-amped), center is Polk CSi4, with a Polk PSW 505 Sub. Anyone looking to upgrade or start a system would be hard pressed to find better sounding and looking equipment than Polk. I really appreciate how good my old vinyl collection sounds now!

Brilliant!

By 

from Leckrone, PA, United States

Comments about Polk Audio Black Bookshelf Pair Speakers:

I have been into audio for 25+ years. I have built many custom systems, for both home and automobile. I am not biased to any particular brand, because every brand has their own unique sound. However, I can say that I have heard many top brands, and these speakers will spray sound with the best of them! Imaging and soundstage are both phenominal. They produce crystal clear highs, and a punchy bottom end. Vocals are rich and very accurate. If you take pride in your system and use top quality speaker wire and components and want fantastic sounding speakers, look no further. I have the black set and they are sweet! Price=10, Looks/Build=10, Sound=9 right out of the box, without break-in!

The RTiA1 is a tremendous ...

By 

from Undisclosed

Comments about Polk Audio Black Bookshelf Pair Speakers:

The RTiA1 is a tremendous product at a very reasonable price. There are a "few" other options worth considering in this price range with various pros/cons, but there are also many choices at this price point and above that don't begin to approach the fit and finish of the RTiA1. Let me first say that I have to agree with most of the reviews in terms of overall build and sound quality - exceptional regardless of price. The only point I would like to raise is the bass issue since the impression I was getting from the reviews prior to purchase was that these can dish out full range sound into the lower registers like a tower speaker might...I even read a review that stated he had to check to see if the subwoofer was on!? After listening for two weeks, my conclustion is that it does in fact take a subwoofer to complete the package. I am a somewhat critical 2-channel audio listener first, and a home theater viewer second. I listen to a wide variety of music and strive for faithful "full range" reproduction of recordings. Some people seem to think that music doesn't require full bass reproduction, but there is plenty of action in the sub-100Hz and even sub-50Hz range in most music. It is always best to test things for yourself in your own space with your own gear, so I ran these full range on stands with power coming from an NAD C326BEE integrated amplifier. I tried placement against the wall and 24" out into my smallish room (roughly 8' x 12') to test bass response. Vocals and acoustical music were phenomenal (especially when placed into the room) - period. There IS lower bass "presence", but very little IMPACT...which is to be expected from this size speaker/driver. In Enya's Watermark recording, there is a descending bass sequence into the 20-30Hz range that completely vanished without the help of a sub. Again, that is to be expected with a bookshelf speaker, but music does indeed contain low frequency content below the usable range of this speaker and you WILL need a sub to reproduce it. The addition of a modest sub I had on hand (AudioEngine's S8) filled in the low end nicely and transformed these into a terrific full range sub/sat system. It seems that you could achieve even greater output in a bigger space with a larger subwoofer as the RTiA1's seemed to be willing to go on beyond the limits of the S8. In short, these are terrific speakers and a great buy for the price...just don't expect them to compete with Polk's towers in terms of "full range" fidelity without a subwoofer. Even in a small room and moderate listening levels, the sub adds much needed depth and realism. I would suggest trying an A/B (sub / no sub) with a familiar recording to see if you notice any "missing content". Aside from the that, my guess is that you will be very satisfied with this little gem. Happy listening!

By

Comments about Polk Audio Black Bookshelf Pair Speakers:

So this review is based on a year of use. These speakers just get better with age. The high and midrange frequency presence is remarkable, the low end clean and not overplayed. I mainly listen to Classical music where clarity is a must, and these little gems are outstanding! The linearity of frequency transition, highs to lows, is seamless. Now moving to more contemporary music, listening to Chicago?s ?Chicago Transit Authority? on CD, Question 67 & 68 absolutely blew me away! The opening which includes bass, percussion and horns hits solid and again, the clarity is amazing. We live in a day of booming bass, but if you want to return to a pure, clean, well articulated sound, the Polk Rti A1 speakers will deliver in as nearly a perfect sound as you may find.
