The Simple Choice
For Surround Performance

The popularity of home theater has thrust the bi-directional surround sound speaker into the spotlight. To get the most from DVD and multi-channel music formats you need a versatile high performance surround speaker. And the Oscar for best performance goes to the FXi50, for its role as the switchable, bi-directional surround FX speaker that gives you the kind of performance and placement flexibility that your high performance home theater demands. The FXi50 surrounds you with action and effects.

The FXi50 features:

  • Reformulated poly-composite Dynamic Balance drivers with butyl rubber surrounds for durability and smooth wide range response.
  • Dual opposing 1" silk composite "Mueller" German engineered dome tweeters for clear, detailed highs.
  • Timbre-matched components to fit into any Polk Audio RTi Series home theater or multi-channel music system; for a more realistic, more seamless surround environment.
  • Design-enhanced diffusion characteristics: triangular cabinets aim drivers and tweeters in opposing directions to produce a more realistically diffuse wavefront and wide, lifelike imaging of surround-sound FX.
  • Conveniently located bipole/dipole switch for the most flexible placement options and highest performance surround effects.
  • Strong built-in wall mounting brackets for easy installation.
  • Gold-plated 5-way binding post inputs for the most secure connections and the most versatile wiring applications.
