LA4 line array loudspeaker
Overview Specs Downloads

Christie® screen channel loudspeakers combine advanced ribbon driver technology with a unique line array design to provide greatly enhanced clarity, dramatically reduced distortion and ultra-fast transient response. Featuring very wide horizontal dispersion and highly controlled vertical dispersion patterns, Christie’s screen channel loudspeakers place sound exactly where it is needed, increasing the optimal listening area up to four times greater than conventional cinema audio systems.

Features:

  • Christie single enclosure coaxial arcuate ​line array design
  • Ribbon driver technology representing the next evolution of loudspeaker design
  • Provides approximately four times the optimal listening area than typical cinema audio systems
  • Enhanced voice intelligibility, low distortion and highly controlled dispersion

Specifications

System type

  • Fixed articulated ribbon driver line array, 2-way, passive, in a single sealed enclosure

Driver components

  • 8 x 6" ribbon drivers with Neodymium magnets
  • 8 x 6.5" paper/Kevlar composite mid-bass drivers

Crossover

  • Linear phase, 2-way, passive, symmetric @ 1.5kHz, 24dB/octave

Frequency response*

  • 70Hz-20kHz @ -6dB

Maximum SPL**

  • 131dB (AES) continuous • 143dB peak

System coverage***

  • 120° horizontal dispersion • 40° 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. Screen scattering effect will result in slight increase of coverage at HF.

**** 3 cables required when flown. See User Manual for details.
