Incredible Sound, Affordable Price

The R40 is an outstanding value. Dual drivers give you the advantages of small drivers (wide dispersion and great midrange clarity) AND the advantages of large drivers (large surface area for wide dynamic range and punchy bass). It's the best of both worlds, and its performance can't be beat at this price.

  • Designed for superior home theater and music performance
  • Front-firing bass port for high efficiency and powerful bass response
  • Slim tower design conserves floor space, occupies less than one square foot
  • Polk's exclusive Dynamic Balance technology for wide response and low distortion
  • Magnetically shielded for safe placement next to your TV without picture interference
  • 5-way binding post inputs for the most secure wire connections
