Product description

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

The CRMS-SRIW/9090 system consists of one RBN401 pro-ribbon driver for HF and a vented 8” mid-bass for LF reproduction; the 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 RBN401’s patented 90-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. This dramatically enhances the depth and width stereo imaging.

Due to the “compression-less” principle of the pro-ribbon transducer, the system has a linear response at any SPL.

The shallow enclosure of 150mm/5.9-in provides for easy, low profile in-wall or ceiling mounting in typical “2-by-6” wall/ceiling constructions. An optional grill and ACO™ color option is available as well.

For full system performance, the CRMS-SRIW 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-SRIW and ALC, significantly increasing response accuracy, regardless of cable length and system impedance, with tight and accurate mid and bass response as result.

The CRMS-SRIW/9090 is developed as a compact reference main / screen system – or as larger 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 mounting is required.

The CRMS-SRIW system is available with 90° x 40° (“CRMS-SRIW/9040”) or 90° x 90° (“CRMS-SRIW/9090”) dispersion pattern.
