Bringing Power and Clarity to Cinema Sound

Cinema-Specific Horn Design

The Acheron horn is specifically designed for cinema, featuring a very soft roll-off outside the well-behaved coverage angle, and it is fixed within the enclosure to ensure accurate acoustic crossover, phase response, and a consistent vertical pattern between the low and high frequencies.

Find The Right Fit For Your Venue Size

With its uncompromising quality and full bandwidth, the Acheron is suitable for small and medium theatres, dub stages, and production and post-production facilities. and for larger theatres with the use of the Acheron LF low-frequency extension.

Self-Powered Design

The Acheron's sophisticated onboard amplification produces consistent and predictable results in any system design, and simplifies installation in both new and existing rooms. Internal signal processing includes an electronic crossover and correction filters along with driver protection circuitry.


Rich, Clean Sound for Theatres Large and Small

Acheron 80/100

At the heart of Meyer Sound’s cinema line of loudspeakers is the high-performance Acheron screen channel loudspeaker. Optimized for installation behind perforated screens, the two-way loudspeaker combines the advantages of self-powered technology and innovative horn design to deliver precise coverage for cinema screen sound channels. Acheron 80 and 100 are identical except for horizontal coverage.

Acheron LF

Designed exclusively to augment the Acheron 80/100 screen channel loudspeakers in larger venues, the Acheron LF low-frequency extension loudspeaker exhibits extraordinarily flat amplitude and phase response for tonal accuracy, exceptional clarity and extended headroom. The self-powered design provides ease of installation and reliability.

Acheron Studio

Designed for smaller theatres and postproduction facilities, Acheron Studio offers the same exceptional fidelity and extended high-frequency performance as Acheron with a convection cooled amplifier for very quiet rooms. Seamless integration with the HMS-10 surround loudspeakers and the X-800C subwoofer create a complete system for smaller venues.

Acheron Designer

An excellent choice for sound designers, screening rooms, small commercial and private theatres, Acheron Designer offers the same operating frequency range as other Acheron models, and the same patent-pending horn technology and high-frequency compression driver. The Acheron Designer also features recessed convection cooling which allows for flat wall placement.

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.

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, self-powered floor 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.
