Product Details

Polk Audio LSiM Series Cherry Floorstanding Tower Speaker, Model LSIM705CHT (Sold As Each)

Whether you enjoy music on vinyl, CD or MP3, or movies on DVD or BluRay®, the performance of the new LSiM Series will transport you. Experience dynamic musical tonality, coherent detail, and natural low frequency reproduction, even at lifelike volume levels. Build a home theater with new LSiM Series components and experience timbre-matched sonics and immersive spatial ambiance, with realistic accuracy and linearity, even at movie theater volume levels.

Key Features:

  • Pleasing tonality, even during extended listening at performance levels.
  • Crisp, lifelike impulses, transients and coherent detail without any unnatural ringing or decay.
  • Natural reproduction of complex low frequency instruments and special effects.
  • Uniform sonic representation within the listening area and immersive spatial impression.
  • Reproduce concert/theater levels while maintaining linearity and accuracy.
  • Compatibility with a wide array of electronics both past, present and future.


  • Dynamic Sonic Engine
    A single molded enclosure within the enclosure that houses the super-accurate Ring Radiator tweeter and Extended Motion Mid-Range Driver, the Dynamic Sonic Engine improves high-frequency dispersion and horizontal off-axis response by reducing performance-robbing back wave reflections.
  • Super Cell Aerated Polypropylene Cones
    Thicker, yet even lighter, Super Cell APP delivers better transient response and incredible detail.
  • Internally Braced Enclosures
    Solid MDF, braced with interior enclosures-within-enclosures featuring non-parallel surfaces, breaks up resonances and internal standing waves. The LSiM707 has five separate internal chambers.
  • PowerPort® Bass Venting
    A patented innovation that eliminates turbulence at the mouth of the bass port, increasing efficiency and enhancing deep, distortion-free bass.
