Product description

The CRMSC-SRHOR surround is a 2-way passive-filtered full range loudspeaker, designed to meet all requirements of current and future cinema surround sound formats.
Featuring the patented Alcons pro-ribbon driver technology, the CRMSC-SRHOR surround combines an exceptional clarity and intelligibility with an unusually high dynamic range, offering the most realistic sound reproduction possible.

The CRMSC-SRHOR system consists of one RBN202 pro-ribbon driver for HF and a vented 6.5” mid-bass for LF reproduction. The CRMSC-SRHOR HF section has an 400 W peak power input, enabling a 1:16 dynamic range with up to 90% less distortion from 1 kHz to beyond 20 kHz.
The patented horizontal dispersion of the RBN202 offers a stable coverage to a larger number of seats in the auditorium; Due to the “compression-less” principle of the pro-ribbon transducer, the system has a linear response at any SPL.

The CRMSC-SRHOR is designed as matching surround system for the CRMSC system: By utilizing identical MHF components, in a horizontal arrangement, 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 15-degree slanted enclosure baffle together with the optional grill and ACO™ color option, provides for easy, low profile wall mounting.

For full system performance, the CRMSC-SRHOR needs to be driven by an ALC controller-amplifier, delivering maximum sound quality with increased headroom and utmost operation reliability.

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

Typical applications include surround sound system for premium Home Cinemas, high-end mix/screening rooms, quality-conscious post-production facilities and dubbing stages. As a result of Alcons’ tight manufacturing standards, all system cabinets are within “matched pair” tolerance.
