Big Speaker Sound...Without the Big Speaker

Beauty and Brawn Come Together

The RM40 is the perfect complement to today's stylish video displays and home theater systems. Its sculpted Pewter-finish Aluminum enclosures look awesome flanking your plasma or flat screen television. High tech materials and features, such as patented Power Port bass venting technology and Dynamic Balance composite structure drivers ensure superior performance, delivering rich, full-bodied, big speaker sound from beautiful, compact packages.

Match the RM40 towers with RM Series centers and surround speakers with a Polk powered subwoofer to custom construct the home theater speaker system of your dreams. (See system suggestions at bottom of this page)

The RM40 features:

  • Stylishly curved enclosures formed of heavy duty, non-resonant Aluminum; the shape breaks up internal standing wave resonance for pure, lifelike sound.
  • The towers feature Power Port Bass Vents hidden under the grilles to extend and strengthen their lower-midrange performance for a seamless blend with the subwoofer output. Unlike competing slim tower systems, with the RM40 you'll experience full, rich, natural voices and other midrange sounds.

Dual 4-1/2 inch (11.4 cm) Mineral Filled Polymer Dynamic Balance midrange drivers for clear, distortion-free midrange even at high volume levels.

  • Broad dispersion design allows everyone in the listening area to hear clear, well-balanced sound.
  • 1 inch (25mm) Dynamic Balance Silk/Polymer Composite Dome Tweeter for sweet highs and more lifelike imaging.
  • Connect your RM40 towers securely and conveniently with their high quality 5-way binding post inputs.
  • RM40 towers are magnetically shielded for safe placement near your state-of-the-art TV or video monitor with no risk of video distortion.
