Crutchfield Customer Review (What's this?)

For the price, they can't be beat. High highs and great midrange. Perfect for the front L&R speakers for a surround system.

Pros: Sound, style, price

Cons: I would recommend with a sub, not much bass out of these.

Lacking

niel from Santa Rosa, CA on 5/4/2018

Crutchfield Customer Review (What's this?)

One thing I want to say first-hand is that these speakers take several weeks of constant play to break in. Otherwise there is virtually no mid-range, so don't be surprised and be patient. I'm only rating these at at 3 because they sound okay, but for my taste, the highs are really grating to an almost annoying degree. The Imaging quality is not there. The mid-range is still lacking after breaking them in. I recommend going with the Polk RTI A7. I returned the s55 for these and am confidently pleased. The tweeters are much sweeter and the speakers image very well. The mid-range is warm and sweet. The s55 is just okay. They do play loudly, I will give them that.

Pros: Nice footprint size. Plays loudly.

Cons: Harsh highs, lacking mid-range. Relatively poor imaging quality.

Good all around speaker

Front speakers for a small room surround sound system and small audio system set up. Works very well. Well built and sounding for the price tag.

Pros: Price

Cons: A little tall and big for a small room.

Full Quality sound for the price

Crutchfield customer from Westminster, CA on 4/7/2018

Crutchfield Customer Review (What's this?)

Perfect for front speakers for theater surround. I noticed a great improvement in the sound quality using the By-Wire installation method. The bottom sound port creates a omni directional sound, unlike most forward projecting speakers. Combined with a quality Subwoofer you have amazing sound W/O trying to drive the Polk woofers their max lower dB level. Best design front covers using neodymium magnets instead of snap in retaining clips that are sometimes difficult to remove, for cleaning the covers.

Pros: Small floor space area required. Great sound when paired without the need for a top of the line Reciever / Amplifier.

Cons: A little to tall free standing next to average electronic stand or cabinet with so many wall mounted tv's

Crutchfield Customer Review (What's this?)

Loving the Signature series! I have the S55's for front L/R, S30 center, the S10 as surrounds, and a pair of S15's for rear surrounds. Low frequencies are handled by a Klipsch Reference R-10SW (sounds fine for an entry level sub, but might need upgrading as the room is large- 17x32'). Using the Yamaha RX-A860 (also from Crutchfield!) for music and movies. The system fills the room and after some tweaking sounds crystal clear, and they look fantastic. Crutchfield helped me get exactly what I wanted and within my budget! If you're considering these speakers don't hesitate! And no need to shop elsewhere, this place is great.

Polk Audio Signature S55 WN ea

james t from Essex, MD on 8/10/2017

I just bought these speakers along with the center speaker S35 and the bookshelves S10 which entitled me to a free subwoofer or credit towards an upgraded one. Of course I went with the upgraded and got the PSW 125. I have a little older Sony receiver that says it puts out 100 watts. It was a big box store all in one box set-up that I've been wanting to upgrade for some time. I don't know a lot about electronics, but I do love listening to my music loud and clear along with watching movies where you can hear the bullets slicing through the air or the rustle of leaves from a tree very far in the background, and this folks provides that and much more. I have heard all my hair bands in a new light. I hear musical instruments in the classics that I have never known were being used in that song. I am beyond ecstatic about this purchase and what it sounds like in my house. My room is small its like 17x25. Even my Mom who is 75 enjoyed hearing Elvis from an excellent sound system!!!!

Pros: Very aesthetically pleasing to the eyes Sounds fantastic Very well built and solid as a rock

Cons: none

Crutchfield Customer Review (What's this?)

I haven't listen to the speakers well enough yet, I haven't connect the biamp, my receiver TX-RZ 810 can only be connected for biamp option resetting the configuration to 5.1 and I have 10 speakers connected to the receiver. so far I am disappointed. My bookshelf Polk Audio sound better, and they are much smaller.

Crutchfield Customer Review (What's this?)

These are my first tower speakers. After hours of research and listening to speakers I chose these and am glade I did. I have a large room and they fill it well, after some break in time they sound great. Alot of speaker for the money.

Pros: nice clean sound, sound good with a cheaper reciver

Cons: none yet

Outstanding sound!

Tom from Tampa, FL on 4/23/2017

Crutchfield Customer Review (What's this?)

One of boxes arrived totally mutilated, but the speaker was OK so far. Even with this the speakers are outstanding, particularly considering their coat. The sound, including base response, is very clean & crisp. I like the small profile of enclosure as it does not over power the room. I totally recommend them.

Pros:

Cons: NONE!

Crutchfield customer from New Baltimore, MI on 3/19/2017

Crutchfield Customer Review (What's this?)

I got these to replace my Infinity P252 speakers after the driver broke. These are a perfect upgrade for the rest of my Infinity surround system! I really get a lot of noticeable extra power with the larger drivers - it's like having stereo bass! Also, the double amping you can send to the speakers is awesome! It's my first set you can do that with, and it literally allows the speakers to receive twice the power! Overall, very happy with a substantial upgrade to my system - thanks to Ryan at Crutchfield for helping me pick these out! Awesome customer service and knowledgeable staff as always!

Features

Dynamic Balance Drivers: 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. Using just the right materials enables Polk to eliminate issues that reduce speaker performance and tune out performance-robbing resonances before they occur. Dynamic Balance ensures a rich, clean, full-range sound no matter what you're listening to. The Polk Signature S55 floor-standing loudspeaker incorporates a Dynamic Balance two-way driver array with one 1" tweeter and two 6.5" woofers.

  • Hi-Res 1" Terylene Tweeter: The Signature S55 floor-standing loudspeaker utilizes Polk's newly designed 1" Terylene tweeter to deliver clear and detailed high-end response for realistic reproduction of vocals and instruments. It will support high frequencies up to 40kHz to perfectly reproduce the latest high-resolution audio files with improved audio extension, earning Hi-Res Audio Certification.
  • Dual 6.5" Mica-Reinforced Polypropylene Woofers: The Signature S55 floor-standing speaker employs two 6.5" Dynamic Balance low distortion mica-reinforced polypropylene cone woofers for clean, clear bass, better linearity, and increased dynamic midrange and midbass. This mica-reinforced polypropylene woofers feature butyl rubber surrounds, massive ceramic motor structures, and high-temperature Conex fiber spiders that combine to create drivers of exceptionally high efficiency, for clean, clear bass, better linearity, lower distortion, and greater durability.

Power Port Technology: The Signature S55 floor-standing incorporates Polk's Power Port technology with a specially designed down-firing port. Power Port technology smoothly transition air flow from inside the speaker into your listening area for deep, extended bass impact while minimizing turbulence and distortion. Polk's patented Power Port technology delivers 3dB more bass response than a traditional ported speaker. Because the port is located on the bottom of the floor-standing speaker, its not necessary to position to the loudspeaker a certain amount of feet from wall - giving you greater placement flexibility.

Non-Resonant Enclosure: The floor-standing speaker's strong, rigid and acoustically inert enclosure reduces unwanted internal standing waves for less audible coloration. And non-resonant Meddite MDF construction, extra bracing, and a thick front baffle ensure a more lifelike sound. The enclosure's curved edges not only look cool, they reduce standing waves inside the cabinet for less audible coloration. The enclosure features a beautiful black washed walnut finish.

Anti-Diffraction Magnetic Grille: The Signature S55 includes an anti-diffraction magnetic grille for unaltered sound. The integrated magnets make it easy to attach and remove the grille from the floor-standing speaker.

Two-Way Crossover: The floor-standing speaker employs a high-performance two-way crossover array (2.5kHz) for seamless blending and optimum time alignment of the tweeter & woofers, creating a lifelike soundstage.

Dual 5-Way Binding Posts: The floor-standing loudspeaker has two sets of 5-way binding posts connected by jumpers. Using the dual 5-way binding posts, you can bi-amp or bi-wire the speakers. The 5-way binding posts will accept bare wire (up to 10AWG), pin-connectors, spade-connectors, and banana plugs (single or dual). The speaker terminals are color coded for easy identification between positive (red) and negative (black).

Dual-Floor Compatible Feet: Customized for improved stability and bass coupling to the floor, the floor-standing loudspeaker's feet are designed for both carpet and hard floors. The feet come pre-installed and should not be removed.

Applications & Placement: The Signature S55 floor-standing speakers can be used as front and/or surround speakers in a home theater setup. They can also be used in a simple stereo application. If your AV receiver offers built-in bass management, the S55 should be set to "Large" for an unfiltered, full-range audio signal.

  • Placement for Front Speakers: As a pair of front speakers in a home theater or stereo setup, create an equilateral triangle between the speakers and the listening position - with the speakers placed as far apart from one another as the listeners are sitting from them.
  • Placement for Surround Speakers: As surround speakers, the S55 should be placed on a side wall slightly behind the listening position. If you cannot place the speakers on the side walls, position them on the rear wall just behind the listening area.

Signature Series: Polk designed its Signature Series of loudspeakers to bring a big surround sound and a live music experience into the comfort of your living room at an affordable price. Featuring Hi-Res certification with a new high-resolution Terylene tweeter, redesigned Dynamic Balance drivers, precision crossovers, an anti-diffraction magnetic grille, modern cabinet styling and exclusive Power Port bass enhancing technology, Polk's Signature series loudspeakers deliver crystal clear highs, detailed midrange, and deep bass; plus they look great in almost any decor. The Signature Series by Polk consists of two center-channel speakers, three bookshelf loudspeakers, and three tower speakers.

Note: You may also want to add one of Polk Audio's powered subwoofers (sold separately) for even more bass response.

Customer Q&A

Crutchfield asked  
Why did you buy this?

price quality [ Brian  Dec 20, 2017 ]
The Signature series has such great reviews are beautiful because someone put thought into their 'design' not just their 'engineering'. The high value doesn't hurt, either. That said, the main reason for the 55s is I estimate the 2 x 6.5" arrangement is just enough to fill my listening space without a sub. I may come back for an HTS sub, though. [ Damon  Nov 24, 2017 ]
Value. Matches other speakers in surround setup. Quick Crutchfield delivery. Polk reputation. Quality sound for the price point. [ MATTHEW  Nov 23, 2017 ]
Like that it matches the center and the acoustics were recommended [ Mark  Oct 10, 2017 ]
Quality and price. [ Ben  Jun 05, 2017 ]
The Crutchfield advisor, Ryan, really helped me get back up to speed on deciding on a speaker that would match my existing system but be a substantial upgrade after my old tower speakers cracked a driver. Really appreciate his patience and advice in comparing different options to find a reasonable replacement. [ Brendan  Mar 04, 2017 ]
I'm an organist, and this is one of the few speakers that can crack 32 hertz (hz); and that is right down there in the land of the 16 foot and 32 foot pipes, the ones that shake your body. [ Timothy  Nov 27, 2018 ]
Reviews say that this is a great middle of the range speaker that is good for both music and movies. The quality and reputation of Polk Audio. Crutchfields knowledge center, fair price and fast shipping was a factor as well and the point program. Cant wait to get them and test them out. [ Eric  Oct 16, 2018 ]
Best low end at an affordable price [ William  Oct 12, 2018 ]
I've heard polk speakers and I like them. I thought the price was very good. [ GERALD  Feb 14, 2018 ]
Needed ah floor speaker. And never had pros with this brand. Should be great! [ GARY C  Aug 06, 2017 ]

2 questions already asked

There are two sets of binding posts. One pair is for the upper frequency range, one for the lower frequency range. There is a metal strip that onnects the two (upper and lower) binding posts. When not bi-amping, then just connect your speaker wire to either the upper or lower posts. When bi-amping, then you use an electronic crossover to separate the higher and lower frequencies. In this case, the crossover outputs have two sets of speaker wire outputs, one set for high frequencies one for low. If bi-amping, then you remove the metal strip connecting the two posts, and connect the high freq. speaker wire from the crossover to the upper post and the low freq. wire from the crossover to the lower post. [ John  Apr 04, 2017 ]
I was curious about that as well. A Crutchfield advisor helped me with it. Basically, bi-amping allows the speakers to receive 2 channels from your receiver rather than 1. In other words, there are two sets of pos/neg posts on the back of these speakers. So, if your amplifier puts out 100w per channel, like mine does, I can now provide these speakers with 200w. You'll have to check your receiver to see if it has bi-amount outputs. My 2010 Onkyo receiver was set up with bi-amping and was labeled as such on the back, and for me I had the choice for either using the channel for high front or bi-amped speakers. The bi-amped output goes to the lower connections. The regular front output goes to the upper connections on the speakers. After setting it up, I also had to go through the setup menu for my receiver to tell it I was now using bi-amped speakers. You may also want to redo you equalization setup (using a setup mic) if your receiver has that feature to ensure to maintain balance for your surround sound. I'm being wordy in the explanation, but it was pretty simple to do, and you can send twice the power to the speakers - I get a noticeable difference! One last thought is to check the output of your receiver to ensure the speakers can handle the extra power. Hope this was of help. [ Brendan  Apr 04, 2017 ]
Hi John Yes the S55 has great bass, haven't really turned off my sub woofer but I think it would do great. Hope the information I gave you will help. Terry [ Terrence  Jul 09, 2017 ]
I would say...no, it's not enough to operate without a sub if your expecting to get solid bass. I guess they do technically hit the low notes, and it provides good depth to the bass for surround sound, but it's just not going to provide anywhere close to the volume you're going to get out of a descent 12" sub. [ Brendan  Jul 08, 2017 ]
