Product description

The CRMSC-SRIW 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-SRIW surround combines an exceptional clarity and intelligibility with an unusually high dynamic range, offering the most realistic sound reproduction possible.

The CRMSC-SRIW system consists of an RBN202 pro-ribbon driver for HF and a vented 6.5” mid-bass for LF reproduction. The CRMSC-SRIW 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-SRIW is designed as matching in-wall surround system for the CRMSC system: 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 ultra-shallow enclosure of 150 mm / 5.9-in provides for easy, low profile in-wall mounting.

For full system performance, the CRMSC-SRIW 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-SRIW 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 in-wall 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.
