Alcons Audio Introduces The CRMS-SRHV Surround

February 6, 2020

The CRMS-SRHV surround is a 2-way passive-filtered loudspeaker, designed to meet all
requirements of current and future immersive surround sound formats.

Featuring the patented Alcons pro-ribbon driver technology, the CRMS-SRHV combines a
benchmark-setting clarity and intelligibility with an unusually high dynamic range, offering a
very realistic sound reproduction. Due to the “compression-less” principle of the pro-ribbon
transducer, the system has a linear response at any SPL.

Typical applications include (height layer) immersive surround sound systems for performing
arts theaters, screening rooms, post-production facilities and dubbing stages, premium Home
Cinemas and quality-conscious PLF cinemas.

The CRMS-SRHV system consists of the RBN401 pro-ribbon driver for HF and a vented 8”
mid-bass for LF reproduction. The CRMS-SRHV/9090 HF section has an 800 W peak power
input, enabling a 1:15 dynamic range with up to 90% less distortion from 1 kHz to beyond 20
kHz.

The patented (90-degrees) horizontal and patent-pending (90-degrees) vertical dispersion
offers a very wide and consistent coverage up to the highest frequencies; By utilizing
identical MHF components, a perfect voicing matching between screen- and surround
system is realized, resulting in an exceptionally wide and uniform sound stage throughout the
entire listening area.

The trapezoidal enclosure together with the optional grill and ACO™ color option, provides
for easy, low profile wall or ceiling mounting.

For full system performance, the CRMS-SRHV needs to be driven by an ALC controller-
amplifier, delivering maximum sound quality with increased headroom and utmost operation
reliability. The system is available in 8 ohms and 4 ohms version, for maximum amplifier
efficiency in individually-amplified immersive surround systems.

The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation
between the CRMS-SRHV and ALC, significantly increasing response accuracy, regardless
of cable length and system impedance, with tight and accurate mid and bass response as
result.

Philip “Dr. Phil” De Haan, head of Alcons R&D: “The CRMS range is our separate group of
solutions for the studio and residential markets. Following our compact immersive systems,
with CRMS-SRHV, we now also have the versatile height or width channel solution for the
larger studios, theatres and screening rooms.”

The RBN401 is Alcons Audio’s most-applied pro-ribbon driver, with thousands in daily use in
professional higher SPL applications.

Phil continues: “As we continue to upscale the possibilities of our patent-pending waveguide
technology, we have optimized the 4” RBN401 to bring the wide 90° x 90° dispersion into the
CRMS range, while utilising the exact same transducers for a perfect voicing-match
throughout the CRMS family. We have already received very positive feedback from the first
critical listening applications that deployed the system.”

The CRMS-SRHV/9090 will see its official launch at the upcoming ISE show at the Alcons
Pro-Ribbon Immersive Experience, in Amsterdam the Netherlands.
