LA5S line array surround loudspeaker
Features 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.​

Features:

  • 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

Specifications

  • 4 x 6" ribbon drivers with Kapton® diaphragm and Neodymium magnets
  • 4 x 6.5" paper/Kevlar composite mid-bass drivers with Neodymium magnets

Crossover

  • Linear phase, passive, symmetric crossover @ 1.5kHz, 24dB/octave

Frequency response*

  • 60Hz-20kHz @ -6dB

Maximum SPL**

  • 128.5dB (AES) continuous • 140.5dB peak

System coverage***

  • 120° horizontal dispersion • 60° vertical dispersion

*Measured at distances of 4m and 8m in simulated, free field and ground plane conditions. Sensitivity is calculated based on measured SPL response averaged in 200Hz-5kHz range and scaled back to 1m.

**AES refers to AES2-2012 standard. IEC refers to IEC 60268-5 standard. Max SPL calculated based on sensitivity and power handling. IEC short-term power tested using IEC pink noise with 9dB crest factor. The crest factor was specifically increased to reflect real-life parameters of digital cinema sound tracks. Maximum peak SPL calculated using peak voltage during IEC short-term power test.

***Averaged in 500Hz-16kHz range, at -6dB 4 3 cables required when flown. See User Manual for details.
