Alcons Audio’s CRS8 is a 2-way passive-filtered full range loudspeaker, designed to meet all requirements of current and future immersive surround sound formats.

More details from Alcons Audio (www.alconsaudio.com):

Featuring the patented Alcons pro-ribbon driver technology, the CRS8 combines an exceptional clarity and intelligibility with an unusually high dynamic range, offering the most realistic sound reproduction possible.

The CRS8/9090 system consists of the RBN401 pro-ribbon driver for HF and a vented 8” mid-bass for LF reproduction. The CRS8 HF section has an 800W peak power input, enabling a unique 1:16 dynamic range with up to 90% less distortion from 1kHz. to beyond 20.000 Hz.

Due to the “compression-less” principle of the pro-ribbon transducer technology, the system has a fully linear response, with the same tonal balance at all SPL’s for an intuitive 1:1 performance.

The patented (90-degrees) horizontal and patent-pending (90-degrees) vertical dispersion of the waveguide, offers a very wide and consistent coverage up to the highest frequencies (20kHz -3dB); Very important for the imaging in height channels of immersive systems.

Driven by the Sentinel amplified loudspeaker controller, the Signal Integrity Sensing™ pre-wiring ensures dynamic cable/connector compensation between the CRS8 and ALC; This offers a 1:1, undistorted natural sound reproduction, regardless of cable length and amplifier impedance load.

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.

Philip “Dr. Phil” De Haan, head of Alcons R&D: “immersive sound is now coming up in a wide variety of applications, demanding a diverse choice of dispersion patterns. Following our initial designs with the patent-pending waveguide technology on the RBN202 pro-ribbon platform, very successfully deployed in the VR5 and CRMSC-SRHV systems, we focused on applying our new waveguide development onto our 4” pro-ribbon transducer platform.”

The RBN401 is Alcons Audio’s most-applied pro-ribbon driver, with thousands in use daily, as critical part of the line-array systems in particular. Now with the integration in the CRS8 reference surround, the wide 90° x 90° dispersion becomes available for larger point-source applications, where extended full-bandwidth coverage is required.

Phil continues: “The missing link has finally arrived, for a perfect voicing-match with the other RBN401 pro-ribbon loaded main- and surround systems, completing the seamless 3D immersive experience.”

The CRS8/9090 is available in two impedance choices: 8 ohms for efficient parallel connection in 5.1/7.1 configurations, and 4 ohms, for maximum amplifier efficiency in individually-amplified immersive surround systems. It comes with a 6 year warranty.
