Product description

The CR1 is an ultra-compact 3-way sound system, designed to meet all requirement of all current and future (digital) cinema sound formats, for applications where medium output, high quality cinema sound reproduction is needed; It is recommended for smaller cinema theatres, as well as screening rooms and Home Theatres.

Featuring the patented Alcons pro-ribbon driver technology, the CR1 offers a 1:1 reproduction of the original sound source; The absence of a “compression threshold”, caters for the same tonal balance at all SPL’s, while the combination of unprecedented low distortion with a very high 1:15 RMS-to-peak dynamic range delivers the most realistic cinematic experience possible.

The patented “Real-90” horizontal dispersion of the RBN401 pro-ribbon, mounted on a revolvable waveguide, widens the stereo experience “sweet-spot” for the off-axis seated audience significantly.

Besides the RBN401, the CR1 comprises a 6.5” vented mid-range and 12” woofer, all with Neodymium motor structures enabling a light weight and compact cabinet design. The unique ultra-shallow enclosure design of only 18cm/7-in. provides for very flexible mounting in even the smallest spaces behind the screen or as surround; Both for on-wall, or in-wall mounting, for which the CR1 is available with front-vented LF (FV).

The low system impedance and fully passive-filtering configuration allows for a very economical power package, where the CR1 is powered and controlled by one channel of an ALC amplified loudspeaker controller; Through the integrated CR1 drive-processing, the ALC offers response optimisation and dedicated protection.

Through the SIS™ (Signal Integrity Sensing) circuit, the cable-length and connector resistance between the CR1 and ALC is completely compensated (system damping factor >10.000), for further increased accuracy and controlled cone-travel, resulting in a tighter mid and bass response.
