Our take on the Polk Audio Signature S35 by Crutchfield's Deia Z.
A flexible, high-performance home theater speaker
Polk's Signature S35 was designed for maximum versatility, with horizontal or vertical placement options. It performs equally well as a left, right, or center channel speaker. You can mount it on your wall or simply rest it on your TV stand. It's a great choice for high-impact surround sound and detailed high-resolution stereo music. And its sleek, stylish design makes it an attractive addition to your living room.
Built for smooth sound
The S35 is made with high-quality materials for natural, low-distortion sound. Housed within its cabinet is a 1" high-resolution Terylene dome tweeter for clear, detailed highs and realistic reproduction of vocals. Six highly efficient 3" Dynamic Balance® woofers are made of lightweight yet durable mica-reinforced polypropylene. The non-resonant MDF (Medium Density Fiberboard) cabinet and anti-diffraction grille provide an acoustically inert structure for reduced sonic interference. Polk's exclusive Power Port technology adds low-end impact.

Most effective part of my Polk 6-speaker home theater. Great clarity. I can hear spoken words that were previously garbled on non-existent. Fits directly below the front of my Sony flatscreen and is unobtrusive. I highly recommend this center channel speaker.

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 S35 center-channel loudspeaker incorporates a Dynamic Balance multi-driver array with one 1" tweeter and six 3" woofers.
- Hi-Res 1" Terylene Tweeter: The Signature S35 center-channel loudspeaker utilizes Polk's newly designed 1" Terylene tweeter to deliver clear and detailed high-end response for improved vocals in movies and music. 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.
- Six 3" Mica-Reinforced Polypropylene Woofers: The Signature S35 center-channel speaker employs six 3" Dynamic Balance low distortion mica-reinforced polypropylene midrange cone woofers for clean, clear bass, better linearity, and increased dynamic midrange. These mica-reinforced polypropylene midranges 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 S35 center-channel incorporates Polk's Power Port technology with two specially designed rear-firing ports. 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.
Non-Resonant Enclosure: The center-channel 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 S35 includes an anti-diffraction magnetic grille for unaltered sound. The integrated magnets make it easy to attach and remove the grille from the center speaker.
Two-Way Crossover: The center-channel 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.
5-Way Binding Posts: The center-channel loudspeaker features 5-way binding posts for a secure connection to your speaker wire. 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).
Applications: The Signature S35's primary use is as a center-channel loudspeaker for home theater applications. But, it can also be used as a left and right front or rear speaker in stereo and home theater setups. If your AV receiver offers built-in bass management, the S35 should be set to "Small" to filter out low bass frequencies.
Placement & Mounting Options: The Signature S35 can be mounted horizontally as a center channel speaker, under or above your flat-panel TV. You can simply place the center-channel speaker on a table-top or shelf, or wall-mount the center-channel using its integrated keyhole slots on the back. Because the S35 is only 4.1875" tall, it will not block the screen or IR remote of most TVs (the included rubber increase the height of speaker by 0.125"). The speaker can also be wall-mounted vertically using the integrated keyhole slots. A wall-mount template is provided (mounting screws not included).
Note: The speaker cannot be mounted vertically on a table-top or shelf (only wall-mounted vertically).
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.

4 questions already asked
I was amazed how much improvement there was in the quality of my center channel audio with this speaker. Dialogue is much clearer. Especially low volume [ William Apr 04, 2018 ]
I sure like mine. It was a great step up from anything I've ever owned [ GREGORY L Jan 25, 2018 ]
If you need to handle more power but I feel all Polk speakers are excellent so? it is up to the $ again [ Don Jan 25, 2018 ]
I pair mine with a pair of Klipsch r-28f towers, I am very pleased with the setup. Great sound for a small speaker, nice fit and finish for a budget speaker as well. I use duel 12" SVS subs for the low end. [ John Dec 21, 2017 ]
I'm sure it's a matter of personal preference, intended use, budget, etc., but I chose a pair of the Klipsch R24F's (because of the small footprint) and a Klipsch R-10SW 10" subwoofer for added bass (for a home theater). I couldn't be happier. The center channel made all the difference in the world; very low profile and dialogue is now crystal clear. [ Joseph Dec 21, 2017 ]
Any of the Polk Signature series would work best. I have a set of the S15's as my left and right channels, they pair great together. [ Andrew Dec 21, 2017 ]
Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Kenny Feb 16, 2017 ] Staff
It comes with a removable (magnetic) mesh/fabric cover, says 'Polk' on it bottom center. [ Casey Jan 24, 2017 ]
Yes [ Terry Jan 23, 2017 ]
All the Polk speakers come with magnetic speaker covers. Nice design & very convenient. Take on and off as you see fit. [ JOHN P Jan 23, 2017 ]
Yes of course! [ Don Jan 23, 2017 ]
Yes, it has a thin cover that attaches with magnets and is easy to put on or remove. The speaker itself looks quite good without it, but the cover makes speaker much more conspicuous, with only small "polk" on the front. [ Noah Jan 23, 2017 ]
Yes, it comes with a cover. [ Kirk Jan 23, 2017 ]
Yes [ Steve Jan 22, 2017 ]
I assume you mean a grille to cover the speakers, and yes it does come with one. [ STEVE Jan 22, 2017 ]
Yes it does come with a cover, shown without the cover so you can see what "under the hood" [ Andrew Jan 22, 2017 ]
If you mean grill, yes it comes with a magnetic grill. Speaker looks good enough to leave it off though. [ Mark Jan 22, 2017 ]
Yes. It is black with the polk name on it. The cover is magnetic and easy to remove or replace. [ Peggy Jan 22, 2017 ]
Yes, this speaker comes with a cover that easily clips on and off. It's attractive either way. [ Joseph Jan 22, 2017 ]
Yes it does. In fact, it's magnetic. [ Mike Jan 22, 2017 ]
Yes [ Joseph Jan 22, 2017 ]
