L-Acoustics L1 and CS1 line array

Key Takeaways

  • L-Acoustics has introduced the L1 and CS1 line array speakers, designed to break performance benchmarks in large-format line sources.
  • The L1 is a powerful primary loudspeaker with significant transducer concentration for high volume output (up to 160dB from 35Hz up to 20kHz).
  • It includes two 18-inch low-cardioid (LC) transducers mounted on the sides, four front-facing 15-inch LF drivers, eight 8-inch mid-frequency drivers, and six coaxial HF compression drivers.
  • The CS1 is a cardioid subwoofer that extends the L1’s frequency range down to 25Hz and provides additional SPL (up to 150dB).

L-Acoustics claims these speakers represent the highest expression of power, bandwidth, and pattern control in line array technology. They have been deployed at venues like the Hollywood Bowl and are designed to manage sound bleed effectively.

The L1 and CS1 are complemented by L-Acoustics Soundvision software, which allows for precise modeling of speaker configurations to optimize sound distribution within different environments.

Additionally, the new line arrays simplify logistics with fewer required units compared to previous models like the K1 series, making them easier to transport and set up at events.
