Product Information

Ultra-High Performance Surround for Thrill-Seekers

The F/XiA6 is at home in the best home theater systems and in very large spaces. With a 6 1/2" Dynamic Balance driver and two 1-inch Dynamic Balance dome tweeters, movies and multi-channel music will fill the space with well-conceived sound effects coming from all directions. These surround speakers will literally immerse you in three-dimensional sound. Configurable as bipole or dipole for discrete and diffuse sound, they work equally well behind you or beside you. For the ultimate 7.1 home theater system, simply add a second pair.


  • The trapezoidal shaped cabinets aim the drivers and tweeters in opposing directions to produce a more realistically diffuse wavefront and wide, life-like imaging of surround sound.
  • With the flip of a switch, Polk's dipole/bipole circuitry changes the sound-field from direct to indirect radiation patterns enabling you to place the surround speaker beside or behind you depending on your listening room setup.
  • Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
  • Polk's proprietary, patented Dynamic Balance technology allows their engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
  • Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a life-time of reliable sound.
  • The F/XiA Cascade Tapered Crossover eliminates the comb filtering and beaming, common to multi-driver speakers, which degrades the quality of the audio and collapses the soundstage.
  • Patented Acoustic Resonance Control (ARC) technology suppresses cabinet resonance that causes distortion to ensure clear and natural sound.
  • Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference.
  • All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
  • Gold-plated, professional-style 5-way binding posts offer the most secure connection options.



  • Dimensions (W x H x D): 13.38" x 14.75" x 8.63"
  • Weight: 13 lbs.
  • Driver complement: (1) 1" diameter mid/woofer, (2) 1" diameter tweeter
  • Total frequency response: 45Hz - 27kHz
  • Sensitivity (1 watt @ 1 meter): 88dB
  • Lower and upper -3dB limits: 55Hz - 26kHz
  • Recommended amplifier power per channel: 45 watts - 27 watts

I just got mine 9/22/17 took my time to install actually read manual. These replaced my Bose speakers. The difference between night and day. If you’re looking for awesome surround these are audio file quality.

Just purchased a pair of the FXiA6 to go along with my RTiA9's, RTiA3's and CSiA6. Wow, what a mind blowing experience. I will only buy Polk from now on, what a great job the Polk Audio company is doing. Now I need to watch all of my movies over again, it will be like watching them for the first. Thanks Polk Audio!!!!!!!!!!!!

Great match !!!
I was in the market to upgrade my rear surrounds from a loaner pair of mb quarts. I have a pair of polk monitor series 2 70's running through a yamaha rxv 477 in a 13 x 18 listening room .As i exhausted all the reviews........ etc. keeping in mind i wanted the best rears to match my polks. I decided on the fxi a4's. After i ordered them i thought i should have chose the a6's. cause the driver size matched my monitors. When they arrived i was still skeptical but, as i hooked these bad boys up......... all my doubts faded away . The clarity and performance the a4 delivers was very suprising !!! The match and performance was perfect. These speakers have been around a while but, now i know why they never went on sale. I highly recommend these speakers. Give em' a try.

Theses things arte monsters! They are a little big and heavy but they sound fantastic and worth the bulky size in my opinion (which is the only one that counts, lol). They bounce of walls and fill up back stage great.

Bought these for Boxing Day last year and still blown away. The bipole dipole switch doesn't do much though but not a big deal.I tried the larger A6s to match better with the A9s but the sound was only marginally better, so I stuck with the A4s.

wow. all i have to say is wow. i recently replaced everything with a complete system from polk. i paired the fxi-4's with the csi-4 center, the dsw 600 sub and the rti a-7's they all compliment each other very well. this stuff is not for the faint of heart. and the day i powered everything up for the first time the police were called to my house for "playing the drums to loud". no joke. enough said?

By far Polk has made listening to all sorts of music and watching tv and bluray movies a whole different world and experience. These speakers paired up with RTi8 towers, just simply put, optimises sound clarity and detail.

All I have to say is that, I now need a CSi A4 to complete my set up.
