Real Wood, Real High Performance.

  • Why settle for vinyl speakers when you can have the warmth and beauty of real wood at the same price, with speakers from the new RTi A Series.
  • They incorporate our latest Dynamic Balance Cone drivers and 1-inch tweeters, with an asymmetric cabinet design that’s as beautiful for the way it controls resonance and increases cabinet rigidty as for the way it lends an elegant touch to any decor.
  • The result is classic Polk performance in a design that speaks to today’s high-end home decor. True performance art.
  • The RTi A7 features the latest generation of Dynamic Balance® polymer composite drivers for smooth wide-range response with low distortion.
  • The RTi A7 uses multiple long-throw 7-inch woofers to combine the wide dynamic range benefits of a single larger woofer with the tight, punchy, accurate bass response of small woofers. Combined with PowerPort Plus, these multiple woofers deliver deep, high-impact bass with speed and accuracy.
  • 1-inch Silk/Polymer Dome Tweeter delivers smooth response and better detail.
  • PowerPort® bass venting for superior clean, low distortion bass that you can really feel.PowerPort vastly reduces "chuffing" or "port noise" and provides deeper, more powerful, lower distortion bass than could be realised with conventional ported or sealed designs of comparable size.
  • Magnetic shielding for safe placement near video sources.
  • Mylar bypass capacitors in the crossovers extend high frequency response and improve detail and transparency.
  • Acoustic Resonance Control (ARC Port) technology for more natural midrange reproduction.
  • Neodymium magnet,low-viscosity ferro-fluid cooling, and a heat sink on the back of the magnet, create better power handling and reliability.
  • Dual, bi-ampable gold-plated 5-way binding post inputs (with wide holes for large-gauge bare wire connections) for the most secure connections and the most versatile wiring applications.
  • Butyl rubber surrounds for high performance durability.
  • Acoustically inert stamped driver baskets.
  • Floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging.
