ACHERON SCREEN CHANNEL 
LOUDSPEAKER
At the heart of Meyer Sound's EXP line of cinema products 
is the Acheron high-performance screen channel loud-
speaker. Optimized for installation behind perforated 
screens, the two-way loudspeaker combines the advan-
tages 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 mod-
els: 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 narrow theatres and re-
recording, production, and post-production facilities.
The Acheron horn (patent pending) was specifically 
designed for cinema use and features a very soft roll-off out-
side the extremely well behaved coverage angle. The horn is 
fixed within the enclosure to ensure an accurate acoustic 
crossover, phase response, and an incredibly consistent 
vertical pattern between the low and high frequencies. The 
Acheron’s 580 Hz crossover point places most of the dialog 
in the horn, which is ideal for cinema applications.
