Meyer Sound 1100-LFC Large LF Array Loudspeaker

Large, low-frequency array loudspeaker in the LEO family - designed for long-throw applications where maximum power is required, such as large-scale tours and installations

Product Description

The Meyer Sound 1100-LFC Large LF Array Loudspeaker 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.

To guarantee optimum performance, design 1100‐LFC systems with Meyer Sound’s MAPPTM system design tool. This intuitive, cross-platform application accurately predicts directional patterns, frequency and impulse responses, and linear peak SPL for 1100‐LFC systems, ensuring that systems deliver the required coverage and SPL.

An optimally tuned, vented cabinet houses the 1100‐LFC’s two 18-inch, long-excursion cone drivers. The loudspeaker’s 28 Hz to 100 Hz operating frequency range complements LEO, LEOPARD, LYON, JM‐1P, and other Meyer Sound loudspeakers, allowing it to integrate seamlessly with line arrays and curvilinear arrays.

The unit’s power amplifier operates at voltages from 208 to 235 V AC, at 50/60 Hz. TruPower limiting ensures maximum driver protection, minimizing power compression while yielding high constant output under high continuous and peak power conditions. A single, field-replaceable module located on the rear of the cabinet contains the amplifier, control electronics, and power supply.

The 1100-LFC cabinet includes protective plastic skids on the bottom that securely align with the cabinet’s top slots. Units are stackable normally or reversed for cardioid configurations. Meyer Sound tunes and vents the cabinet to specifically optimize it for low air velocities.

Suspend line arrays comprising up to 16 cabinets at a 5:1 safety factor and BGC V1 from the optional MTG‐1100 top grid. For touring and portable systems, the optional MCF‐1100 caster frame accommodates three-cabinet stacking of the 1100-LFC for secure travel. Optionally available durable nylon covers, accommodating stacks of two or three 1100-LFCs, ensure complete road-readiness.

Meyer Sound’s RMS remote monitoring system comes standard with all 1100‐LFCs and provides comprehensive monitoring of system parameters from a host computer running Compass control software via the RMS interface. Convenient 5-pin XLR connectors allow the use of composite cables carrying both balanced audio and RMS signals (3-pin XLR audio connectors are optionally available).

Meyer Sound constructs the 1100‐LFC cabinet with premium multi‐ply birch and coats it with a slightly textured black finish. A powder-coated, hex‐stamped steel grille with acoustical black mesh protects the unit’s drivers.

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
