Our take on the Polk Audio FXi A6 by Crutchfield's Loren Barstow
The Polk FXi A6 surround speakers combine top-notch home theater performance with flexible placement options. These cleverly designed rear-channel speakers feature two tweeters aimed 45° from each other, for an ideal mix of direct and indirect sound.
Dipole/bipole operation for flexible placement
A dipole/bipole switch lets you position the FXi A6s on the rear or side walls of your home theater room you'll get great results either way. If you place them behind your listening postion, set them to bipole mode for distinct, directional sound. Or set them to dipole mode for side placement, and they'll create a more diffuse soundfield for convincing wraparound effects.
A high-tech approach to accurate sound
Polk carefully designed the drivers using laser testing to help identify and eliminate resonance points. The acoustically inert MDF cabinets fight internal vibrations that can compromise performance. It all adds up to enveloping surround sound that fully immerses you in the movie action.

Dramatically improved surround sound! These speakers are in dipole mode and they almost eliminate speaker location effect even sitting close to them. I was amazed at the sound of a good action movie. They are also very musical. Driven by Marantz SR5012.

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 6.5" 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 dual 1" silk/polymer dome tweeters that provide clear, detailed highs and spacious surround effects. Each tweeter uses a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.
Frequency Response: The overall frequency response is 45Hz-27kHz and the -3dB frequency response is 55-26kHz.
Enclosure: Each enclosure has a triangular shape with the speaker faces angled at 45 degrees. One face has a tweeter and a woofer, while the other face has a tweeter and port tube opening. A switch for selecting Dipole or Bipole operation is located on the rear of the speaker above the speaker's 5-way binding post speaker terminals. One of the speakers is specifically designed for the "left" channel and the other for the "right" channel.
Acoustically Inert Cabinets: Each speaker cabinet features all-MDF construction with internal bracings that virtually eliminate sound-muddying resonance. The speakers are finished in either a black or white laminate finish.
Anti-Diffraction Grilles: The floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging.
Port: On the side with only a tweeter, there is a single port tube opening for increased and extended bass response.
Dipole/Bipole Switch: There is a switch that allows each speaker to be used as a Dipole (out of phase) or Bipole (in phase) speaker. If you're mounting the speakers on the side walls in line with your listening position, the dipole mode will create a diffuse, ambient soundfield. If you're placing them behind your position, the bipole mode fires the drivers in phase to flood your room with surround sound. When used with a Dolby Digital system, the surround speaker setting should be set to small.Wall Mounting: The bracket on the back of each speaker has two keyhole slots, allowing the speaker to be mounted on the wall using the supplied 2-1/2" wood screws.

Have owned a pair for 20+ years and they still rock. However, purchased new Denon receiver which has more power output than my current Polks can handle. [ DAVID Oct 15, 2017 ]
I've owned nothing but Polk speakers for years, including two pairs of older FX speakers that sound amazing. I'm sure these will be even better! [ Keith Sep 30, 2017 ]

It is very awesome sound, also compare with high end rank speaker. This is enought for me to feel it. [ Thi Aug 12, 2018 ]
Hello Jeremy, I haven't hooked them up as my wife doesn't want speakers behind the couch. I do definitely think they would work just fine in a 7.1 system though. [ Thomas Aug 12, 2018 ]
Yes [ Gene Aug 12, 2018 ]
I personally have these setup in the back of my living room and I'm very happy with their performance. If my living room was larger I would most definitely be buying an additional pair as my side speakers. [ Marc Aug 12, 2018 ]
Yes, worked well in my rectangular room. [ Rolan Aug 12, 2018 ]
Thats what I bought them for [ Chris Aug 12, 2018 ]
Yes, they work great as a side speaker as long as your wife doesn't mind them sticking out from the wall. They sound great! [ Jeffrey Aug 12, 2018 ]
Yes. They are a little tall depending on your space. Due to size they do have a slightly "richer" sound than the 4's. That said I ended with the 4's side and rear due to size. If I had space I'd have the 6's all around. I'm assuming you have fronts and center good enough to match/better them. If not I'd go 4's. [ Patrick Aug 12, 2018 ]
These speakers are definitely powerful enough for a room that size. However, the are better suited as the rear speakers in a surround system design, as in the back pair accompanied by tower speakers or something similar providing the front end balance. I have them backing up a pair of Polk tower speakers and a Polk center channel. [ JAMISON P Dec 11, 2017 ]
To answer bluntly, yes. The long answer is...Thats about the same volume room I have mine in. The room is 18x34, 8' ceiling, open down 1 18' side. They are mounted 6' off the floor to the bottom.I have an Onkyo txnr777 receiver (220w/channel) and no amp, with Polk s55's up front and an HSU sub. Listening position is between them with the couch against the same wall they are mounted on. I used the accu setup on the AVR which (surprisingly) set everything flat, but did shorten the distance from 8' actual to 7.2'. After listening for a bit, I increased the output by 2db and think it sounds great. They are crossed at 80hz. I like to hear the rear speakers and not just let them provide ambient sound. On bipole setting they are very well balanced with music in 5.1and provide easily localizable soind while maintaining the ambient. I am not at all disappointed with their performance or quality and would buy them again. Think you will be happy with them also, depending on the quality and power of your front speakers. Be aware, they are fairly large, about 16" tall x 14" wide x 12" off the wall, but look good and are surprisingly unobtrusive in a large room. [ James Dec 08, 2017 ]
That sounds like a fairly large room. I think it depends on what speakers you plan to use up front, where you are going to place these, etc. My feeling is you'd probably be happier with something a little bigger - my room is about 15x15 and they are placed to the sides which works great. [ ANDREW Dec 08, 2017 ]
Unfortunateky the S1 does not have any provision for rear speakers. Dolby is decoded into 3.1 channels (left, right, center. Sub) with some speaker tricks making virtual surround. There is no broadcast method or decoding method for the rear channels. If you haven't bought this yet and want a 5.1 soundbar then I would suggest Samsung, Sonos or Vizio. All of their upper end soundbars are wireless rear compatible. [ James Oct 31, 2017 ]
My FXi A6 speakets are excellent dipole rear surround speakers that truly hold there own with the rest of my high powered lineup, but they are not wireless to my knowledge. I had to bury the wires before I drywalled. The only polk component i own that is wireless is my DSW PRO 660 subwoofer, but have it wired with high end sub cable. [ JAMISON P Oct 30, 2017 ]
Cannot recommend a brand but just about any should work that set the speaker at just over ear height when listening. If I were to stand mount I would make sure it had some kind of back on it as well as a shelf that worked with the triangular footprint. [ James Dec 08, 2017 ]
I do not have any recommendations on stands for these speakers, I actually have them mounted on my wall as rear speakers. I did this because of the layout that I have in my basement, because they play sound in two different directions it's perfect as the rear on my surround sound 9.2 and they also act as speakers for my bar which is located behind the surround [ Dante Nov 23, 2016 ]
