Clear Detailed Spacious Vocals

By Josagan

from Florida

Comments about Polk Audio High Performance Center Channel Speaker:

I purchased the CSi A6 Center Channel Speaker on 12/18/14 to compliment my Bi-amped Polk Monitor 70 Tower Speakers and SVS SB-1000 Subwoofer using a Onkyo AV Receiver, Dune HD Media Player, and OPPO Blu-ray Player. I liked the specs: 55-26k Hz frequency response, 90 dB Sensitivity, 20-200 watts power range, 6-1/2" woofer and dome tweeter in a bass reflex forward ported cabinet all combined to produce clear detailed spacious vocals without being harsh and overbearing or sounding "boxy". It's important to set the center channel speaker configuration Crossover Frequency settings in your AV receiver to your sound preference and listening area dimensions. THX recommends setting the crossover frequency at 80Hz but I prefer setting it to full band. After four months using the CSi A6, movies, music, and even regular TV all sound great. I am very happy with it. It was money well spent and I expect it to last for many years of listening pleasure.

Great Balanced Audio and Soundstage

By BriDown

from Baltimore, MD, United States

Comments about Polk Audio High Performance Center Channel Speaker:

I have had this speaker now for about a week- not even broken in yet. I was a little concerned since I was replacing a relatively new TSX250c Center that I was pleased with. I replaced it because I have RTiA3's for fronts and RTiA1's for surrounds. I noticed the TSX was not really timbre matched with my other speakers. The TSX has a good balance of tones from top to bottom. I was worried about losing that balance and the crispness of the speaker. My worries couldn't have been more wrong. The CSiA6 has great rounded sound, a wide soundstage and hits the highs as well as the lows, and everything in between. My system now sounds complete as this center matches my other speakers providing fluid sound and continuity. It does seem to be power hungry. Audyssey previously set my TSX at -6 to -5.5 when running setup. Audyssey sets this Center to -1.5 and I increased it by 1db to stand out a little from the surrounds to better hear dialogue. Overall, I made a good choice in purchasing this speaker and should have gone with it in the first place. I was trying to save pennies by going with the TSX without the previous understanding of how important it is to have your speakers match. After hearing it, I get it now. As a side note, many people blanket their crossover frequencies at 80 not paying attention to whether the speakers are capable of those frequencies. I did the same with my previous setup. The result is worst sound and over working of the receiver. When you have speakers that can handle the crossover frequency, the sound is more robust, clear and natural. This Center, the CSiA3 and the RTi speakers can handle the frequencies and I notice a huge difference in the quality of sounds. Buy it, you want regret it.

Perfect to say the least

By CraigC

from Binghamton, NY

Comments about Polk Audio High Performance Center Channel Speaker:

I have purchased the CSIA6 along with 2 RTI A9, 4 RTI A7, and 2 RTI A5 to complete my Home Theater for a 9.2 setup. The sound is amazing for movies and music, but the main purpose for doing all floor standing speakers was for some seriously loud, clear, concise sound and these all deliver the quality I was hoping for. My old setup was coming from Paradigm with 2 fronts floor standing, 2 di-pollar floor standing, 2 book shelves and center channel of course. They were great and when making the move to Polk I was really hoping for that same quality of sound and was happy that Polk's RTi speakers exceeded my expectations. I am very happy with this setup.

      Comments about Polk Audio High Performance Center Channel Speaker:

      Polk makes some very nice speakers and more recently have produced some higher end quality systems. Like Cerwin Vega most of there speakers are oriented toward loud rock with the emphasis on the low end.
      This speaker falls into that category. The sound is clear with no distortion at any volume. But it is a center channel were 80% of what is directed to it is dialogue. The occasional boom from an explosion in a movie is great, but not everyone has a baritone voice when speaking. I am using this speaker with a surround bar that has its own sub woofer. The voices from it are more natural and the woofer only cuts on when necessary as directed by the crossovers.
      I do like the speaker and will keep it. It is replacing a old Infinity center channel that was clear and crisp but lacked the volume control and low end that the Polk has to offer. I am saying yes to recommending it but one must keep in mind that it is bass heavy and that must be taken into consideration when matching it with your current system.

      **Center of bass** .....iHave'nt even pushed it wide open yet and the lows had me greatly satisfied. I just upgraded from the TSi CS 20. And I thought that was a great center. But this bad boy took the cake. It's worth the extra bread if you where thinking about the A4.

      I was debating on this center for a long time now to match my RTi12's and I was so so glad I did get this center, they blend beautifully together. In my setup I have this beautiful center (cherry finish) with a DSW PRO400 with the Polk RAti12's mains bi-wired and rears I have ODS Kevlar 6.5" 2-ways with 1"silk tweet and my sub stage two martin logan dynamo

      I did something a little ...

      By SERIOUS7

      from Undisclosed

      Comments about Polk Audio High Performance Center Channel Speaker:

      I did something a little different when i purchased the CSIA6 center speaker on July 19,2012 .. First i removed the Gold Bussbars from CSIA6 terminals then i bi-wired the monster to my TX-NR Onkyo 1009 with double banana plugs which were piggy-back on the Center speaker terminals on the receiver to feed signal to the Mid-woofer and Tweeter independently ...I don't believe in mix-matching my speakers , i want everything to come from the same house .. So by adding the monster to my TX-NR Onkyo 1009 i'm able to push 9 Polk speakers , 5 in the front and 4 in the rear plus the Sub.. For the money i laid out i expect to get as much as i can from this Bad Boy ... I intend to utilize the Normal power as well as the Dynamic power from the 1009 to feed this very "Efficient" speaker... I'm very very satisfied with the quality of the sound coming from this monster.. Since the normal hearing range is 20Hz to 20KHz the Tweeter highs(a falsetto 27KHz) are noticed when a Xylophone, Cymbals,Piano or String instruments are being played along with any other high note that's detected.. The Mid-Woofer(45Hz,= a mini Baritone..!!!) vocals are Super clear from my DVD's,Tuner,CD's and Direct TV and there are times when audio sounds somewhat three dimensional .. No more adjusting the volume, now the audio is strong and true... I have absolutely NO complaints , i'm proud and very happy with this handsome behemoth and the way it blends with my RTi12's and i would like to add i'm using the speaker "Bussbars" that's the gold speaker terminal clamps which help my RTi12's soundfield and imaging .. Some guy's fail to use these Bars but they feed signal to both sets of Speaker terminals.. If you buy the CSIA6 Center Masterpiece, you won't regret it ,this is some piece of work ...

      from Undisclosed

      Comments about Polk Audio High Performance Center Channel Speaker:

      I bought this 3 days ago after reading numerous reviews about how the center channel is the most important speaker in your home entertainment center I decided to go BIG or go home. I have all sorts of products from Bose but decided after hearing a good friends system to try Polk I bought this with a pair of matching rti a3's. Needless to say this are amazing right out of the box they need to be set as large and 60hz on you receiver. The imagery in this center is fantastic while watching a movie everything pops and is very clear. The tweeter is pristine very clear and not enough to make your head hurt even while putting your ear up to them on a loud setting. Mid bass is complete there's not a frequency missing and for lows well... Depending on your musical preference I have this with the matching bookshelves speakers and don't really need a sub on for watching most movies. The clarity is so well I was cleaning with the tv on their was a loud scene on my be for a commercial for a new action movie I was near my right speaker and jumped. While this is on at any volume it is clear and crisp no rattling or distortion of any frequency. I have a new onkyo receiver 5.1 85 watts a channel these take advantage of that receiver and push to their full potential. It wonderful expecially coming from a Bose lifestyle to this. I'd give it 100 stars if possible thanks for making me a believer Polk.

      By Anonymous

      from Undisclosed

      Comments about Polk Audio High Performance Center Channel Speaker:

      Note: HT is 19' X 11.5', w/Pioneer 60" Plasma ~ 14' from the viewing / listening position, and a 6'8" H X 5' W five feet opening behind the futon. I've enjoyed HT thru 4 receivers since 1992 (Sherwood, Yamaha X 2, and now a Pioneer SC-07). I worked in motion picture theaters from 1969 to 1974, even operating an early automated projection booth. I spent many hours smiling in the back of a "road show" theatre watching Santana & 10 Years After @ Woodstock. 8 24" for the rear RT7s (fronts were on 24"). Classy high stands are mostly unobtanium + cost = Polk's larger towers . . . Resulting purchase? = 4 Polk RTi-A9s, CSi-A5, 2 FXi-A6s + used Velodyne 15" sub; and a Pioneer blu-ray player. Would I be pushing the sound barrier (wife's refusal to stay in room @ appropriate movie dB level)? Her answer is NO. She could hear the improvements. Vocals following the screen image across the room. UFOs rising over her shoulders & blasting thru the screen. Bombs bursting in air, we felt for the coffee table. Still there! Setting the audio levels was essential. The SC-07's capabilities exceed mine using a SLM. The RTi-A9s' high frequencies were slightly trimmed for best results. Listening @ the sweet spot to Jeff Beck @ Ronnie Scott's on BR, a 19YO said "best sound I've heard outside of a club." Although I'd given the wife the DVD of the firefly series; she found sonic & visual improvements with the BR. Our cable co just passed thru digital on the basic pkg; network TV is now great. Last weekend, we were watching The Prince of Persia. As I was surprised to hear a desert thunderstorm, I paused the Blu-Ray. WOW, there's the first thunderstorm of the spring going on outside! That's the most positive result I can give for Polk's success with the RTi-A line: it's as naturally sounding as the world around you. Again, NOTE: my HT room is 11.5 X 19 FEET, w/ 6.5' X 5' hole in the wall 5' behind the listening position. The sound is seamless; and although my wife often sits in the recliner near the wall ~ 7' from the RF A9, movie audio is discernible coming from the positions of the other 6.1 speakers when appropriate. Don't be afraid to fill your room with Polk sound.

      This speaker sounds ...

      By Steve in STL

      from Undisclosed

      Comments about Polk Audio High Performance Center Channel Speaker:

      This speaker sounds Amazing. I auditioned a lot of speakers before deciding on the polk RTi & CSi lines. Overall they sound excellent and for the price range nothing else really came close to me. I auditioned both the CSi A4 and the CSi A6. The CSi A4 is no slouch by any means, but the CSi A6 is a must if the space is not an issue. It is big, but with it comes big and beautiful sound. I really wanted the C4 and was impressed with it, but the A6 fills out the mid range so much better I had to get it even though space was an issue for me. I liked it enough to rearrange my living room in order to accommodate it. The main reason for this is that the center channel does MOST of the work in the home theater setting, so I figured the fuller sound was a must.
