Product Details

Polk Audio Black Floorstanding Speakers, Model RTIA5BK

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. The RTi A5 uses two long-throw mid-woofers combined with PowerPort to deliver deep, high-impact bass with speed and accuracy
  • 1-inch Silk/Polymer Dome Tweeter delivers smooth response and better detail
  • 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
  • Magnetic shielding for safe placement near video sources
  • Mylar bypass capacitors in the crossovers extend high frequency response and improve detail and transparency
  • Acoustic Resonance Control (ARC Port) technology for more natural midrange reproduction
  • Neodymium magnet, low-viscosity ferro-fluid cooling, and a heat sink on the back of the magnet, create better power handling and reliability
  • Dual, bi-ampable 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
    • Timbre-matched to fit into any Polk Audio home theater or multi-channel music system for a more realistic, more seamless surround sound environment
    • Integrated feet with installation optional floorspikes in an outrigger base to provide stability on any type of flooring
    • Real Wood finishes at vinyl prices

Let me preface by saying you could include myself the group of audiophile snobs, having experience with brands like Thiel, Definitive Tech, Kef Reference, etc. I recently started looking to replace my old speakers and decided to research some new Polks. My criteria was to find a speaker with a textile soft dome tweeter and to avoid some of the newer "metalized" mid woofers and tweeters cropping up in so many brands these days. I found the Polk's design materials more consistent with my philosophy. So my research led me to the RTiA5 due to the following attributes. - use of tall slender cabinet avoiding use of stands - attractive real wood and nicely finished - use of two 6 1/2 midwoofers for midrange coherence - bi-wire availability - functional curved cabinet avoiding resonances. After listening, I am astounded how good these speakers sound. These speakers are neutral if not slightly warm, and invoke no listening fatigue. Their midrange is the most coherent I've ever heard. The word imaging is thrown around by so many people. However, if you want to experience what a true speaker image sounds like, try these speakers. Many speakers can throw a wide soundstage, but collapse in the center image. These did not, and provided for exceptional two channel listening. Don't worry, any speaker that can pull off two channel sound can do multichannel. (I just ordered a center and bookshelves from this series to complete my set!) If you have a subwoofer, then stay with the A5's, because the multiple drivers in the A7's or A9's will reduce coherence. Without a sub: go for em'! No more bleeding ears for me, Matthew Polk to the rescue! I am done throwing money away on "high end speakers." My advice is to start here and stop here, and spend your extra cash on other things you enjoy. You won't be disappointed! Remember: metal is for pots and pans, not for speaker drivers. If metal didn't resonate endlessly, they wouldn't make cymbals out of it! By the way, every cent spent on these speakers comes back in the very best sound available, a true value.

Setup: Amplifier: Onkyo TX-SR 707 100 WPC, bi-amping capability Fronts: Polk RTi A5 left & right, Bi-amped, High Pass Filter = 80 Hz Subwoofer: Polk DSW Pro 500, LFE Low Pass filter = 80 Hz Crossover: 80 Hz Cable: Jamo 1.5 mm2 These speakers can decently handle low frequencies as low as 80 Hz or lower up to 40 Hz. Setting the crossover to 120 (as what could be deduced from RTi A series specifications of the other two higher models), would result in the overall sound being drowned in base by a decent sub such as DSW Pro 500. The high frequencies are disappointing. The mid frequencies are somewhat disappointing. I have tried several listening modes including the highly acclaimed THX to extract a good reproduction of high and mid frequencies but they seem not there. I have a pair of Bose 301 which I initially intended to sell and to be replaced by polk RTI A5's. I know that Bose 301 have excellent high frequency reproduction so I tried putting them as my right and left surrounds and, Oh my God!, the combination is amazing when the listening mode is set to All Channel Stereo. It's like the RTi A5's were reproducing the mid to lower ranges and the Bose 301 the higher frequencies. Positioning yourself at the center of the mixture point is like sitting at the heart of music. Listening is like euphoria, you just don't know what it is exactly; It's, like, taking your breath away. Watching movie is rather disappointing because the fronts cannot accurately reproduce enough highs and the upper mids are somewhat muffled and the 301's cannot accurately handle lower frequencies. This results to specific sounds driven in a particular channel being inaccurately rendered when this setup is used for home theater. Bryan Adams' voice in the song "please forgive me", sounded thin, but sounded remarkable and full with the aid of 301's. This is not to say 301's are necessarily better. Leaving Bryan adams' voice to the 301 sounded shrill and raspy. Kenny Rogers' voice on the RTi A5 sounded full, with an unnoticeable improvement upon 301's backup. Classical music "Greensleves" was acceptable on RTi A5, but was a mile better, sounded fuller, crispier and more enveloping with the aid of 301. Santana feat Chad Kroeger's "Into the night" was a little disappointing in the RTi A5 alone but sounded remarkable with RTi A5 and 301 together. Gunther's "You touch my tralala (Ding dong song)" is excellently reproduced by the RTi A5's, particularly the part where air is being pumped out. Drumbeats in Michael Jackson's "Liberian girl" were excellent on RTi A5, but leaving the instruments insipid and flat. Bi-amping RTi A5 is not necessarily better for receivers with 150 WPC, 8 ohms, or lower as the sound is almost inaudible and undefined at lower volumes. Sound acquire substance only within a short range, before primary signs of distortion sets in. undefined: lower than 40 full with good substance: 55-75 distortion becomes noticeable: 85 based on using onkyo tx-sr707 Overall, RTi A5 is a good speaker (I am still overwhelmed by its price considering its performance) when used for listening to music as long as it is backed up by speakers that can handle higher frequencies better, and mixing them to produce a stereo (All Channel Sterero). However, it is poor when used for movies. Home theater speakers should have the ability to reproduce sound accurately at any given frequency in its range at any given channel, which neither Polk RTi A5 nor Bose 301 delivered independently.

update on the rtia5 speakers

By 

from Mpls, MN, United States

Comments about Polk Audio Black Floorstanding Speakers:

This is an update to my last review, (zimmy), and after having these in my living room for a while, and adding a Polk audio psw111 sub, and an ONKYO HT-RC 560, receiver I am just loving these speakers now, the sub is very helpful and the new HT-RC560 receiver really woke up my system, and I've gotten used to the darker finish now, and I don't even look back to the Bose 10.2s anymore, but they were an 1980s model. thanks Polk audio for the great products.

Comments about Polk Audio Black Floorstanding Speakers:

I recently purchased these to replace a pair of 26 year old vintage Polk 5 Jr bookshelf speakers. The RTi A5 has a tweeter design that's different enough from my old speakers that its taking a while to get used to it. The frequencies are all there, it just sounds different, and I find myself missing the dispersion and sound qualities from my old speakers. But as the days go by I'm adjusting to the new sound and I'm happy with it. The bass is more than adequate for my tastes. But then again, my basis of comparison are vintage bookshelf speakers, and I already own a Polk subwoofer, so there's that. Even without the subwoofer, the bass is an improvement over what I had before. I wasn't expecting it to knock the pictures off the walls and wouldn't want it to anyway.

Comments about Polk Audio Black Floorstanding Speakers:

I have always been a fan of Polk Audio! One of my first home theater speaker sets included 4 Polk Rti6's (2 for fronts, 2 for rears) and a Csi3 center channel. I loved that setup, however, I was wanting to upgrade to tower speakers for the fronts, in hopes for a bigger, more theatrical sound. I was working at Best Buy at the time in the Magnolia Home Theater department, so I had a good idea what to look for in a speaker. We carried Polk speakers in the store, but not in the Magnolia department. All we carried was the Tsi lineup (still great speakers, though). I was lucky enough to visit a Fry's store one day and they had the Rti A5's set up for demo, and after hearing them in store, it confirmed to me that I wanted to stick with Polk! I went ahead and ordered 2 Rti A5 towers, 1 Csi A4 center channel, and 2 Rti A1 bookshelves for my rears. I already had an 8" B&W subwoofer. As soon as I received the shipment at home, I couldn't wait to get these speakers set up (It was like Christmas morning)! From the first time I played these speakers, I was fully impressed at the overall sound quality. They still had the brightness of the Rti6 bookshelves that I used to have, but Rti A5's brought so much more warmth and sound depth! They have a very bright sound to them, however, not overwhelmingly bright. They make for the perfect speakers for movies, especially at their price point. Trust me, we sold far more expensive speakers at Magnolia that wouldn't beat these Polk Rti A5's! They blend very well with my B&W sub as well! Every now and then I will play a CD on them, and just go to stereo mode on my Onkyo receiver, and theses speakers perform! They have great stereo separation, great imaging, and great overall dynamic sound. They have decent low frequency performance, however, I would definitely recommend a subwoofer to go with these to give you a more full bottom end to your audio. I've had these speakers for almost a year, and now that they are broken in and well-seasoned, they sound even better than when I first bought them! I love what Polk did with the overall design and build to the new Rti lineup. The new curved shape gives them more of a modern and classy feel to them, and the wood veners can blend in easily with just about any decor! I went with the black color to matchup with my TV and TV stand, and pretty much all my components are black. I know with these speakers, I won't have to worry about replacing them for 10-20 years down the road! Overall great purchase decision! I would highly recommend these speakers to anyone, especially those who are looking for a budget-friendly speaker without compromising on sound quality!

What can I say....Polk's sound and quality are hard to surpass in this price range. My system: A modest Harman/Kardon AVR 354 Polk RTi A5 fronts Polk RTi 70 rear Polk CS245i center And to fill the low end...A Velodyne DLS-5000R sub. 15" 1000 watts of pure thunder. Couldn't be happier, better than goin' to the movies.

Comments about Polk Audio Black Floorstanding Speakers:

SOOOO awesome! These speakers are extremely hard to beat for the price. I work at an electronics retailer and get to experience "good" audio all the time. The main problem people seem to have is that you never really know how speakers will truly sound in your home environment. I researched for a month straight before deciding to go with the RTi A5 and they were perfect. I placed them in my small basement room and played a lot of test audio from different sources. Music had more life than I had had with my previous bookshelf speakers, but the A5's are obviously not intended for music, so I can't say that these are the most musical speakers ever. Testing these speakers with movies was a whole new ball game! Watching movies in stereo was a delight with VERY spacious sound reflecting off the walls. I was floored at how wide the soundscape was in my room. My wife thought my surrounds were on. I seriously rewatched 10 movies just because I wanted to hear how these sounded with these speakers. I loved them so much that I gave away my trust Klipsch center channel and bought the CSi A6 (also a FANTASTIC speaker!). I love these speakers and encourage anyone looking for a very good home theater experience to consider the RTI A5's. Also of note: the cherry finish is gorgeous!

Comments about Polk Audio Black Floorstanding Speakers:

I just moved into a new house with wood floors and I had a pair of black Polk RT1000's that I had enjoyed for years. Originally I wanted them for the beautiful wood cabinet to match the house. I was originally looking at the A9's but after further research and consult with the very helpful salesman at Polk I decided they were too power hungry and overkill for me. I am running them off a Onkyo 100watt reciever and have a subwoofer. Well to get to the point when I first hooked them up and listened to some music my jaw dropped. I can't explain how much better these sound over my older speakers. I can hear every detail down to the softest whispers to the booming bass notes. I am very impressed and would highly recommend them to anyone in the market for a beautiful looking and sounding set of main speakers. I loved them so much I ordered the matching center speaker to replace my old Polk cs400i. Can't wait for that to arrive.
