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).


  • 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.
