Features

  • Optimized design for smaller cinemas - up to 55 ft (16.6 m) in length
  • 3-way selectable, bi-amplified or full passive screen channel system
  • Heavily braced, MDF low-frequency enclosure for extended bass response
  • 6.5-inch horn loaded midrange driver provides highly articulate dialogue
  • Very shallow 14.5-inch (368 mm) depth reduces space required behind the screen
  • Advanced crossover circuitry protects the HF and MF drivers from over- powering and excessive low-frequency program material

* U.S. Patent 7,367,423
