Product description

The CRMSC-SRIW/120 system is a 2-way passive-filtered full range loudspeaker, designed to meet all requirements of current and future immersive sound formats.

Featuring the patented Alcons pro-ribbon driver technology, the CRMSC-SRIW/120 surround combines an exceptional clarity and intelligibility with an unusually high dynamic range, offering the most realistic linear sound reproduction possible at any SPL.

The CRMSC-SRIW/120 system consists of one RBN202 pro-ribbon driver for HF and a vented 6.5” mid-bass for LF reproduction; the HF section has a 500 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 120-degrees and patent-pending 90-degrees dispersion up to the highest frequencies not only offers a very wide and coherent direct-field coverage, it also guarantees a consistent reflected diffuse-field.

By utilizing identical MHF components within the CRMSC range, a perfect voicing matching between each screen- and surround system is realized, resulting in an exceptionally wide and uniform sound stage throughout the entire listening area.

The revolvable RBN waveguide and ultra-shallow enclosure of 100 mm / 3.9-in provides for easy, low profile in-wall or on-wall mounting in typical “2-by-4” wall constructions. An optional grill and ACO™ color option is available as well.

For full system performance, the CRMSC-SRIW/120 needs to be driven by an ALC controller-amplifier, delivering maximum sound quality with increased headroom and utmost operation reliability.

The CRMSC-SRIW/120 is available with 4 or 8 ohms impedance, for maximum amplifier efficiency in serial-connected (5.1/7.1) or individually-amplified (immersive) surround systems.

The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the CRMSC-SRIW/120 and ALC, significantly increasing response accuracy, regardless of cable length and system impedance, with tight and accurate mid and bass response as result.

The CRMSC-SRIW/120 is developed as an ultra-compact reference main / screen system – or compact surround system in immersive sound-for-picture applications. It can also be used as full-range sound system in any installed audio application, where a very high quality sound reproduction with inconspicuous in-wall or on-wall mounting is required.

As a result of Alcons’ tight manufacturing standards, all system cabinets are within “matched pair” tolerance.
