LS2C line source ceiling loudspeaker
Overview Specs Downloads

Employing the same ribbon driver technology present in our screen channel ​loudspeakers, Christie's line source surround loudspeakers feature a unique integrated waveguide design to provide enhanced clarity, and reduced distortion. In addition, the inclusion of the ribbon driver provides ultra-fast transient response. Our line array surround loudspeakers offer the same benefits while also providing perfect timbre matching and extremely uniform coverage for seamless listening experience throughout the auditorium.

Note: Safety cables are recommended any time a loudspeaker will be positioned overhead in an auditorium.​


  • Unique integrated waveguide design for very wide, controlled dispersion patterns
  • ​Ribbon driver and paper/Kevlar composite cone drivers
  • Dramatically higher RMS to​ peak max SPL ratio than compression driver systems
  • Ideal for use as surround channel loudspeaker, with or without bass management
  • Heavy duty marine grade plywood cabinet with integrated mounting points
