LA3i line array loudspeaker
Features 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

  • 12 x 3.5” ribbon drivers with Kapton® diaphragm and Neodymium magnets
  • 8 x 5.25” paper/Kevlar composite mid-bass cone drivers

Crossover

  • @ 1.5kHz, high power, heat sink cooled air core inductors, polypropylene capacitors

Effective Frequency Range*

  • 90Hz-20kHz

Maximum SPL***

  • 127dB continuous • 128.8dB long term

System coverage****

  • 100° horizontal • 40° vertical

*According to IEC 60268-5 standard. Calculated at –10dB.

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

***Continuous power handling tested for 2 hours using IEC noise signal. IEC refers to IEC 60268-5 standard. Max SPL calculated based  on sensitivity and power handling.

****Averaged in 500Hz-10kHz range, at -6dB. Screen scattering effect will result in slight increase of coverage at HF.
