Meyer Sound 900-LFC 3100W Powered Subwoofer with 18" LF Driver...
Product Overview
The Meyer Sound 900-LFC is a compact self-powered low-frequency control element for scalable low-frequency reinforcement across touring and fixed installations. This configuration combines a no-rig cabinet with factory weather protection, suiting ground-stacked or pole-mounted outdoor and semi-exposed deployments. A single 18-inch long-excursion driver and an onboard class D amplifier deliver high continuous output with extremely low distortion. It is a natural low-frequency complement for Meyer Sound LEOPARD line array systems.
Product Description
This weather-protected no-rig variant adds factory environmental protection to the standard 900-LFC while omitting the rigging frame, keeping cabinet weight at 136 lb for ground-stacked and pole-mounted use. The cabinet houses a two-channel open-loop class D amplifier rated at 3100 W peak in a single field-replaceable module. The integral pole-mount receptacle pairs the unit with ULTRA Series loudspeakers, and RMS remote monitoring reports operating parameters to a host computer. Units transport in stacks using the optional MCF-900 caster frame. For flown weather-protected applications the rigging-equipped variant or the larger Meyer Sound VLFC arrayable subwoofer may be preferable, and the matching array system is the Meyer Sound LEOPARD line array loudspeaker. Browse the full Meyer Sound collection for processing and accessories.
