Product Details

Polk Audio RTi A7 Black High-Performance Freestanding Loudspeaker, Model RTIA7BK (Sold As Each)

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:

The RTi A7 features the latest generation of Dynamic Balance® polymer composite drivers for smooth wide-range response with low distortion. The RTi A7 uses multiple long-throw 7-inch woofers to combine the wide dynamic range benefits of a single larger woofer with the tight, punchy, accurate bass response of small woofers. Combined with PowerPort Plus, these multiple woofers 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 insert stamped driver baskets.
  • Floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging.

All-MDF construction and asymmetric cabinet design. 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. (Cutaway view of RTiA9 shown right, bracing is similar on other RTi models)
  • 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.

PowerPort Plus is an enhancement in Power Port technology. Power Port Plus uses two ports (one front, one rear) and internal "plates" to further reduce air turbulence and increase bass efficiency. PPP allows even lower frequency tuning and lower turbulence for less noise and distortion, and more big musical bass, even at lifelike volume levels. This technology delivers performance that vastly exceeds conventionally ported speakers with bass that you truly feel, as well as hear. Learn more about PowerPort® Plus.

These weren't even on my radar when I started shopping for new speakers. I wanted something that could deliver superbly recorded classical music as well as the crystal acoustic work of Tony Rice and the gut punch electric of Stevie Ray Vaughn.......I found them. These RTi A7's bettered B&W and Magneplenar that cost 2 and 3 X's their price. I'm delighted with them and plan to add a couple more for another room in the future. BTW - Crutchfield's customer service was excellent, sorry I can't say the same for their shipper UPS ...or should I say OOPs!

These speakers have good bass and treble, but a weak midrange and no presence. Connected to a Denon AVR-2311CI, voices get lost in the background.

Comments about Polk Audio Black High-Performance Freestanding Loudspeaker:

I am replacing a RM7/8 9.1 system which was awesome in my old 12x8 foot living room. I now have a 20x24 Man Cave and the RM8's could barely fill the room with sound. I am not an audiophile so i will not comment on the sound other than I LIKE IT. I still need to replace the RM's with RTI a3's But need to save money ATM

Current system Marantz SR7009
2x RTI a7 Front
2x RTI a1 Rear
2x RM7 Front wide
2x RM8 Side
1x CSI a6 Center
1x PSW 111 sub

Excellent speakers for the money...

By 

from Florida, United States

Comments about Polk Audio Black High-Performance Freestanding Loudspeaker:

I have owned a pair of the ATi7's for six years now, combined with a ATi6 center channel and two ATi1's for a five channel system. The Polk Ati series are not only fine sounding speakers, but the cabinet finish and design is just as nice as the sound. The sound quality is clean, and easy to listen to for hours at a time. They reproduce music well, from Jazz to Classical. I would recommend these, for the price, they are a bargain....

I picked the right speakers.

By 

from Columbus, NJ

Comments about Polk Audio Black High-Performance Freestanding Loudspeaker:

First let me preface this review by saying I bought these solely for music. I spent quite a bit of time researching various brands. After narrowing the list down I spent as much time in various stores listening to each brand, unfortunately there was no one stop place. Finally I narrowed it down to these and one other brand. I decided on these and boy am I happy. I have these paired with an Onkyo NR636 receiver and I am in heaven listening to them. The are clean, crisp and hold true at any volume. In fact my wife who is a casual music listener even said "I never heard music like this, it sounds so different". If you are reading this and are unsure about what speakers to buy, STOP wasting your time these are unbelievable!!!!!!!

Great speakers! Good value!

By 

from Denver City, TX, United States

Comments about Polk Audio Black High-Performance Freestanding Loudspeaker:

Bought my A7s about a year ago in Cherry & absolutely love them. They are beautiful! They reproduce sound very well, my cd collection & mp3s have come alive. Have the A6 center & 4 A5s as surrounds & wides with an HSU sub & doesn't get any better imho. Am thinking of getting an amp to drive the mains otherwise, they still sound good but am curious what they'll sound like with power just for them. My avr is an 818 & when setting up just the fronts, they were wonderful & adding all the other speakers did dimenish their perfomance somewhat, hence getting the amp.

Basso Profundo

By 

from Niagara Falls, NY, United States

Comments about Polk Audio Black High-Performance Freestanding Loudspeaker:

If there is bass in the signal that reaches these speakers, they will reproduce it, faithfully. Ask my down stairs neighbor. I would, but he no longer speaks to me.
