LS2 line source 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

*Measured at 2m on tweeter axis in simulated free field conditions. Near field measurements were used for low-frequency data.  Sensitivity is calculated based on measured SPL response averaged in 200Hz-5kHz range.

**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. Continuous power handling  tested using IEC60268-1 noise signal for duration of 2 hours.

***Averaged in 500Hz-12kHz range, at -6dB
