Meyer Sound 900-LFC 3100W Powered Subwoofer with QCLP and Rigging F...
Product Overview
The Meyer Sound 900-LFC is a compact self-powered low-frequency control element engineered for scalable low-frequency reinforcement across touring and fixed installations. This configuration combines the QuickFly rigging frame with QCLP weather protection, making it suited to outdoor and semi-exposed deployments where flown or ground-stacked subwoofer arrays are required. A single 18-inch long-excursion driver and an onboard class D amplifier deliver high continuous output with extremely low distortion. It serves as a low-frequency complement for Meyer Sound LEOPARD line array systems.
Product Description
This weather-protected QCLP variant adds environmental protection to the standard 900-LFC while retaining the integrated rigging frame. The captive GuideALinks enable flying from the MG-LEOPARD/900 multipurpose grid in LEOPARD arrays without a transition frame, and support ground-stacked configurations with uptilt or downtilt. Standalone subwoofer arrays can be set at splay angles of 0, 1.25, 2.5, 3.75, or 5 degrees. Inside, a two-channel open-loop class D amplifier rated at 3100 W peak resides in a field-replaceable module, with RMS remote monitoring reporting operating parameters to a host computer. The integral pole-mount receptacle pairs the unit with ULTRA Series loudspeakers. For larger low-frequency formats consider the Meyer Sound VLFC arrayable subwoofer, and pair it with the Meyer Sound LEOPARD line array loudspeaker. Explore the full Meyer Sound collection for processing and accessories.
