750-LFCVery Compact Low-Frequency Control Element


750-LFC

Big-System Sound in a Small Subwoofer Package

Low-Profile Low-End Enhancement

The 750-LFC low-frequency-control element’s impressive power-to-size-ratio and versatile features make it the right choice for any application demanding superior low-frequency performance in low-profile systems. It pairs perfectly with ULTRA-X40 and LINA systems, extending response down to 36 Hz for deeper, richer bass with total control.

Large-System Linearity, Lightweight Design

The 750-LFC offers the same linearity as its larger siblings, the 900-LFC and 1100-LFC in our smallest, lightest arrayable subwoofer. Its 15-inch, dual-voice coil, long-excursion driver faithfully reproduces source material across the entire low-frequency spectrum, offering extremely low distortion and optimized phase response.

Unprecedented Power for Its Size

The 750-LFC is driven by a two-channel, open-loop Class D amplifier that provides discrete, precisely synchronized power to each voice coil. This efficient, lightweight design, coupled with sophisticated signal processing, means you can count on the 750-LFC to reproduce low frequencies at high continuous levels with clarity and punch.


More Bass, for More Applications

Extended Low End, Installed or On the Road

The 750-LFC’s compact footprint gives you the flexibility to bring superior low-frequency performance to situations where space is at a premium—whether you’re on tour or designing fixed installations for venues ranging from theatres and houses of worship to corporate spaces and theme parks.

Take Your System to the Next Level

The 750-LFC lets you bring your existing system to its fullest sonic potential. It pairs seamlessly with both LINA and ULTRA series systems, and with an optional rigging frame, can be flown with LINA arrays without a transition grid. And its integral pole mount supports one or two speakers, for streamlined rigs.

Sophisticated Software Gives You Complete Control

Tailor 750-LFC’s performance with pinpoint accuracy, using Meyer Sound’s software tools: Optimize system configuration with the MAPP-XT™ acoustic-prediction program, apply corrective EQ and fine-tune with the Galileo® GALAXY loudspeaker management system, and monitor system performance in real time with optional RMS remote monitoring.

Effortless Rigging, When Every Minute Counts

The 750-LFC’s active design means no amp racks, no long cable runs, and no gain and crossover calibration to worry about. And its light weight and hassle-free hardware make it easy for anyone on your crew to get the system up and running, fast.

The Self-Powered Advantage

Meyer Sound has been pioneering self-powered loudspeakers for professional installations and touring since 1995. We’ve committed to self-powered systems because we know they deliver unrivaled clarity, reliable performance, value, and ease of use.

If you’ve been thinking about investing in a self-powered system, you’ve come to the right place.

John Meyer

First, a Little History...

The story of self-powered loudspeakers is in many ways the story of Meyer Sound itself.

In the 1970s, sound reinforcement technology was inconsistent science at best, and at worst, led to show-ending failures. A young John Meyer, designing loudspeakers for San Francisco’s McCune Sound Service, wanted to bring quality and reliability to sound systems, and he knew the answer lay in self-powered loudspeakers. In 1979 Meyer founded his own speaker company; early Meyer Sound innovations include the iconic HD-1 self-powered studio monitor launched in 1989.

Today Meyer Sound offers a full range of self-powered sound reinforcement products. Meyer Sound systems can be found on tour with artists ranging from Ed Sheeran to Metallica, on Broadway and London’s West End, and in performance venues from the San Francisco Opera to the Vienna Philharmonic not to mention sports stadiums, cruise ships, and houses of worship around the world.

Why Self-Powered?

Self-powered loudspeakers offer several advantages over their passive counterparts when it comes to fidelity, reliability, and simplicity. The great part is, you’ll start to reap the benefits of a self-powered system before you even power up.

Ease of deployment: System set-up is so much easier when you have fewer components and fewer cables to worry about being miswired. Since self-powered loudspeakers incorporate amplification, you’ll never have to deal with matching speakers to amplifiers or connecting components. You don’t have to worry about calibration of gain and crossover setting which means more time focusing on the show. Eliminating amp racks doesn’t just streamline system deployment, it streamlines your inventory whether you’re a rental house or a road warrior. And when you consider that the average amp rack weighs nearly 300 pounds and takes up four feet of truck space, the efficiencies get even clearer. Let alone when you want to fly the amplifier racks to get closer to the speakers, often requiring more rigging points and more motors.

Predictable, reliable operation: Internal amplification is closely matched to drivers. Because individual components have been optimized during manufacturing, you can expect consistent sound from show to show. Built-in, factory-optimized protection circuitry provides extra assurance without degrading signal quality. And, when you have less equipment, you have less risk of failure.

ULTRA X-40

Better frequency and phase response: Because self-powered loudspeakers incorporate sophisticated processing, they are calibrated to exhibit optimal response curves in key performance parameters. Active crossovers are more precise, sophisticated designs, and bi-amped systems are time aligned, eliminating phase issues. The result? Accurate sound throughout the speaker’s range, at any volume level.

Unparalleled clarity: In powered monitors, internal amplifiers are precision-matched to drivers, delivering optimal power at all times for cleaner sound. And because amps are built into loudspeaker cabinets, there’s no need for long lengths of connecting cable, which can become prone to distortion and signal loss.

Tighter transients: Since self-powered loudspeakers have very short internal cables, amps inside can more effectively dampen driver mechanical motion, which leads to better sonic accuracy and tighter, crisper transients. (And, there’s none of the loss in levels and signal quality inherent over long cable distances.)

Certified Safe: Nothing matters more than the safety of your staff and customers. Because self-powered loudspeakers incorporate amplification, they must undergo rigorous testing by Underwriters Laboratories and other international organizations to ensure they operate safely and guard against the risk of fire, electric shock, and inadequate structural design. Enjoy peace of mind knowing Meyer Sound powered products are certified by FCC, UL, CSA, CE, and CEE the most stringent agencies in the business.

The Problems with Passive

What about passive loudspeakers? At first glance, passive systems may seem like a bargain. But we already know that passive systems require more components and accessories than powered systems. Sonically, they exhibit potential for signal loss over distances, and it is very hard to ensure consistent, optimal sound and volume as amplifiers have many variables to consider when being matched to loudspeakers, such as cable lengths and gauge as well as the number of speakers connected to the amplifier.

Passive systems are often touted as easy to service. But because powered loudspeakers are so complex to design and build, self-powered loudspeakers usually represent the top innovations from leading manufacturers. Better quality translates to better reliability, which means fewer maintenance issues in the long run.

At face value, passive systems might seem less expensive and easier to maintain. But once you start adding in amps, cables, and other components not to mention increased transport and labor costs you’ll find that those savings just don’t add up to a better value.

Step Up to a Self-Powered System

Once you recognize all of the advantages inherent in self-powered loudspeaker systems, it’s easy to understand why the world’s top venues and productions rely on them to deliver consistently stunning sound.
