Meyer’s 1100-LFC (low-frequency control) element is a powered dual 18” subwoofer with an operating frequency between 28 and 100 Hz. As part of Meyer’s LEO family of products, the 1100-LFC pairs perfectly with the LEO-M, LEOPARD, LYON, Galileo GALAXY, and more. The 1100-LFC includes a built-in 8100W peak amplifier and draws between 208–235V AC, 50/60 Hz. Its low-frequency output is incredibly clear, even at more intense volumes.
From the Manufacturer
The 1100‑LFC low-frequency control element is a self-powered
loudspeaker defined by its sonic linearity in reproducing lowfrequency 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 MAPP™ 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.
The optional MRK‑1100 rigging kit, available as a factory-installed
option or field upgrade, includes captive GuideALinks™ that
allow the loudspeaker to be flown from the MTG‑1100 top grid.
Convenient pinned handles and slots make the GuideALinks,
located at the front and rear of the cabinet, easy to set. The
GuideALinks also accommodate reversed units for flown cardioid
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
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. Other options include weather
protection and custom color finishes for fixed installations and
applications with specific cosmetic requirements.
