Meyer Sound 900-LFC Powered Subwoofer

Meyer Sound 900-LFC compact low frequency control element reproduces low frequencies at high, continuous output levels with extremely low distortion. The 900-LFC offers the same sonic linearity as Meyer Sound 1100-LFC low-frequency control element in a smaller, lighter cabinet, making it an ideal solution for small- to medium-sized touring applications and fixed installations. A newly designed class D amplifier provides unprecedented efficiency to the 900-LFC, significantly lowering distortion while reducing power consumption and operating temperature. The onboard amplifier and control circuitry are contained in a single, field-replaceable module. In addition to pairing with LEOPARD systems, the 900-LFC integrates easily with other Meyer loudspeaker systems, including LEO-M, LYON and Ultra Series.

Features:

  • Compact cabinet with small footprint and extraordinary power-to-size ratio
  • High peak power output with extremely low distortion
  • Exceptional linearity, transient reproduction, and low-frequency clarity
  • Self-powered for simplified setup and increased reliability
  • Stackable and flyable in regular and cardioid arrays, with tilt and splay options
  • Integral pole-mount receptacle easily pairs the subwoofer with ULTRA Series loudspeakers
