The RT25 is an amazing little speaker. Its sound is clear, clean and open. It images better than speakers costing many times its modest price. It features:

  • Designed for superior home theater and music performance
  • Exceptional deep bass response provided by patented Power Portª venting technology (Power Port mounted on the back of the enclosure)
  • Anti-diffraction bezel and grille system minimizes grille-edge reflections (diffraction) for more open, spacious and life-like imaging
  • Polk's exclusive Dynamic Balance technology for wide response and low distortion
  • Smooth, natural midrange reproduction thanks to patented Acoustic Resonance Control (ARC) port technology
  • Magnetically shielded for safe placement next to TVs without picture interference
  • Wall mounts via a key hole slot that is molded into the rear-mounted power port
  • 5-way binding post inputs for the most secure wire connections
