Speakers
Acheron 80/100
At the heart of Meyer Sound’s EXP line of products is the Acheron high-performance 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 exceptional, precise coverage for the left, right, and center sound channels for cinema.
The Acheron loudspeaker is available in two full-range models: the Acheron 100, with a 100-degree horizontal by 50-degree vertical horn, which is ideal for wide theatres; and the Acheron 80, with an 80-degree horizontal by 50-degree vertical horn, which is suitable for more narrow theatres and dub stages.
Acheron LF
As part of the EXP line of cinema products, the Acheron LF loudspeaker can be paired with the Acheron 80 or Acheron 100 screen channel loudspeaker to deliver the low-frequency headroom required by larger theatres. The self-powered Acheron LF with dual 15-inch drivers boosts the headroom on the LCR channels be converting each Acheron loudspeaker to a system with three low-frequency drivers in an aligned column.
Acheron HMS-10
Meyer Sound’s HMS-10 is a full-range two-way loudspeaker optimized for surround channels in theatres and dub stages. Designed to complement Acheron screen channel loudspeakers for a complete EXP system HMS-10 maintains a wide dynamic range, full fidelity, and clarity during the most demanding of digital soundtracks. Boasting a wide frequency range of 55 Hz to 18 kHz and a maximum peak SPL of 126 dB with very low distortion, the HMS-10 ensures that the full intensity and nuance of cinema surround channels reach each listener without compromise.
