Polk Audio

Our take on the Polk Audio RTi4

Polk has redesigned their best-selling RTi series speakers for even better audio performance. The RTi4 bookshelf speaker dishes out surprisingly rich, full sound for such a compact model. It takes advantage of the latest generation of Polk's Dynamic Balance® drivers — the 5-1/4" woofer and redesigned 1" silk/polymer tweeter provide smoother response and better detail than the RTis of the past. And these speakers don't just sound great; with its real wood veneer in your choice of black oak or cherry finish, they look great, too.

As always, Polk has paid close attention to the details. The RTi4's cabinet features all-MDF construction with extensive internal bracings that virtually eliminate sound-muddying resonance. It also includes Polk's exclusive Power Port technology for clear, deep lows, and an ARC (Acoustic Resonance Control) port for more natural mids. Dual gold-plated 5-way binding posts allow for bi-amping or bi-wiring.

The RTi4s do a great job with stereo music on their own, or you can team them with a powered sub for rib-rattling results. For dynamic, detailed movie sound, use 2 pairs as your home theater's front and surround speakers. For larger rooms, the RTi4s work perfectly as surrounds in combination with RTi tower front speakers.

Recommended center channel speaker: Polk CSi3.
Recommended surround speakers: Polk RTi4.

Features

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 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 uses a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.

Acoustically Inert Cabinets: Each speaker cabinet features all-MDF construction with extensive internal bracings that virtually eliminate sound-muddying resonance.

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.

Wall Mounting: The Power Port back plate on each speaker has a keyhole slot, allowing the speaker to be mounted on the wall using optional hardware.

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

Note

Frequency Response Note: The overall frequency response is 50Hz-27kHz and the -3dB frequency response is 60-26kHz.

Great Deal, Great Sound

Written By Doc Jones, Newport News, Va on Wednesday, February 08, 2012
 
Got these for a STEAL and upgraded over my old TSi100's which are now on rear channel duties. Polk once again delivers great audio from a small package at a truly reasonable price. Blu-Rays are now that extra bit more immersive and detailed. Watching Tron: Legacy is simply amazing. The only thing I wish was improved was the low end response. I currently have no subwoofer so i do not completely blame the RTi's for this however by having no sub it does show the slight lack of low end response. Polk did a great job with these little guys but there is only so much one can do with a 5 1/2" woofer.
Pros:
Solid design and Craftsmanship, Precise sound and Great Power Handling
Cons:
Wish there was a little more punch in the lower ranges

Nice but not WOW

Written By Jaybe Crow, North Carolina on Saturday, February 04, 2012
 
I am still getting used to these speakers. They replaced a beloved pair of Boston Acoustics HD8. The Polk Audio RTi4 put out a strong mid-range sound for the size. They are being used with a basic stereo set up on 22 inch high stands. The price was right. For the size, they put out a sharp, crisp, full sound for my classical and jazz music, but they don't have that WOW factor in that you don't "feel" the music. They are not as sharply defined as my old Boston's, but I am content with them.
Pros:
Great value for the price I paid for them. Good sound for size.
Cons:
Lacks definition in the lower range.

I bought SEVEN pairs! Love 'em!

Written By OCD, Urbana OH on Monday, January 30, 2012
 
Years ago I was setting up my system in our TV room. I bought the tower Polks and the center Polk, but didn't want to spend $400 on rear and side rears. When I found these I couldn't reisist. I bought 2 pairs. 1 for the kithen and 1 set for bedroom. I liked them so much I tried them in the rear of my system and WOW they were amazing so bought 2 more pairs to replace the one I stole for the bedroom and kitchen, so 4 pairs total. THEN I saw they were in cherry finsh too so bought a pair for the bathroom (ran off of bedroom amp). Made 5 pairs. THEN I bought a pair for each of my kids. SEVEN pairs. Do you think I like them? THEN as a bonus I found an add for a FREE Polk sub with a $499 purchase so 7 x $150 got me TWO free subs...I loved THAT deal! They sound great on my Onkyo basic 110W per channel middle of the road surround and just the two of them sound amazing on 130 Yamaha in bedroom (no surround...yet). So bottom line...when your room has four of these in the rear, 2 Polk towers in the front, 1 Polk center, and a Polk sub it is unreal. Best I've ever heard. The CLEAR crisp pure sound is like no other. I find myself listening to the wierd noises like bullet cases hitting the floor or keys going in the ignition and bugs flying...so clear and music rocks like they are BIG speakers. Buy them if you can!
Pros:
crisp, clear, well made, good bass for a "small" speaker, good looking, sturdy, perfect tone not too high or low, plenty loud, perfect for me.
Cons:
Not a con but if want a little more of a "full" sound with more base, get the towers, but for what these are for no cons period.

Super Speakers

Written By DanL, Central PA on Thursday, January 26, 2012
 
These are smallish book shelf type speakers, their sound represents a great compromise between size and performance. I would certainly recommend them to anyone who wants to listen to a variety of music, where sound quality, space, and price are considerations. They even are nicely styled (I prefer the wood look) either in black or cherry style wood veneer. So, to recap, they sound good, look good, and are reasonably priced. I'd recommend them to anyone.

RTi4 Speakers

Written By Bert G, Spring Hill, FL on Friday, January 20, 2012
 
I purchased (2)RTi A7 Polkaudio speakers, a Polkaudio CSi A6 center speaker, Polkaudio OWM3 speakers for rear rear surround and a Polkaudio DSWpro660wi subwoofer from Crutchfield to go with my Onkyo AV TX-NR709. That turned out to give me an unbelievably great sound system for movies and music. I was considering bookshelf speakers to use for front height to make it a 7.1 system when. I am surprised at how great they sound. They work together with the rest of my system to create a wall of sound. Thank you, Crutchfield for the timely email that not only saved me money but gave me exactly what I wanted.
Pros:
Outstanding build quality, true to life sound at a very good price
Cons:
None
