Overview

At the heart of Meyer Sound’s EXP line of cinema products are the Acheron™ high-performance screen channel loudspeakers. The Acheron Studio is a compact version of the Acheron 80, making it ideal for small theaters, re-recording stages, and postproduction facilities. Optimized for installation behind perforated screens, the two-way loudspeaker combines the advantages of self-powered technology and innovative horn design to deliver exceptional, precise coverage for the left, center, and right sound channels for cinema. Offering the same 38 Hz to 17 kHz frequency response as the Acheron 80, as well as a generous peak output with very low distortion, the Acheron Studio stands up to the most demanding of digital soundtracks, maintaining a wide dynamic range and full fidelity.

The Acheron Studio uses the same patented horn technology originally developed for the Acheron 80. Designed specifically for cinema use, the horn features a very soft roll-off outside its extremely well-behaved 80° horizontal by 50° vertical coverage pattern. The horn is fixed within the enclosure to ensure an accurate acoustic crossover, phase response, and incredibly consistent vertical pattern. The 580 Hz crossover point places most of the dialog in the horn, which is ideal for cinema applications.

Designed and manufactured at Meyer Sound’s headquarters in Berkeley, California, the Acheron Studio’s drivers include one 15-inch low-frequency cone driver and one 4-inch high-frequency diaphragm compression driver. Both drivers yield uncompromising quality and full bandwidth and are powered by sophisticated onboard amplification. The proprietary Meyer Sound power amplifier is a two-channel, class AB/bridged amplifier with complementary MOSFET output stages that yields a total output of 700 W. Built-in signal processing includes electronic crossover and correction filters—to achieve a flat phase and frequency response—along with driver protection circuitry. The self-powered design not only ensures consistent results but also simplifies installation in both new and existing rooms.

The optional RMS™ remote monitoring system provides comprehensive monitoring of loudspeaker parameters from a Mac® or Windows®-based computer running Compass® Control Software.

Constructed of premium multi-ply birch, the Acheron Studio enclosure is coated with a slightly textured black finish. An optional version of the loudspeaker is available with side rigging attachment points and the MYA-AST mounting yoke.
