HMS-10 SURROUND LOUDSPEAKER
Meyer Sound's HMS-10™ is a full-range, two-way loud-
speaker optimized for surround channels in cinemas,
theatres, and re-recording stages. The self-powered
HMS-10 maintains a wide dynamic range, full fidelity, and
complete clarity during the most demanding of digital
soundtracks. As part of the EXP line of cinema products, the
HMS-10 is optimized for use with other EXP loudspeakers,
including the Acheron
®
screen channel loudspeakers.
Boasting a wide frequency range of 55 Hz to 18 kHz and a
maximum peak SPL of 126 dB at 1 meter with very low dis-
tortion, the HMS-10 ensures that the full intensity and
nuance of cinema surround channels reach each listener
without compromise.
The HMS-10’s transducers include a 10-inch low-frequency
long excursion cone driver and a 2-inch diaphragm high-fre-
quency compression driver on a symmetrical constant-
directivity 80-degree horn that delivers exceptional cover-
age. The proprietary drivers — designed and manufactured
at Meyer Sound's headquarters in Berkeley, California — are
powered by two channels of onboard amplification that
include an active crossover, driver protection, and frequency
and phase response correction circuitry.
