Description

Meyer Sound 1100-LFC Large Low-Frequency Array Loudspeaker Weather Protected with 3-Pin XLR and Rig

The 1100‑LFC low-frequency control element is a self-powered loudspeaker defined by its sonic linearity in reproducing low frequency transients at high continuous output levels with very low distortion. This ultra-low distortion, coupled with exceptional headroom and optimized rigging options, makes the 1100‑LFC a flexible tool for low-end directional applications for large-scale tours and installations.

Features:

  • High peak power output with low-frequency clarity and excellent transient reproduction at extreme levels
  • Linearity ensures low-frequency output with consistent directional properties in a variety of configurations at any level
  • Tuned, vented cabinet optimized for low air velocities
  • Stackable and flyable in regular and cardioid arrays
  • Seamlessly integrates with LEO, LYON, LEOPARD, and other Meyer Sound loudspeakers
