Product description

The CRMS-LFE18sl is a slim-sized reference subwoofer system for very demanding listening applications, delivering a super accurate bass and sub response for a maximum quality audible and sensible performance.

Specific attention has been paid to obtain a linear response in the operating bandwidth, while handling ultra-low frequency transients with maximum control.

The 18” custom-designed woofer features a large motor structure with dual 3” voice-coils offering an extreme excursion of 30 mm / 1.2-in. resulting in a 10 dB more excursion capability than a traditional (pro) 18” woofer. (not included in SPLpeak spec).

The direct-radiating transducer mounted in the internally-stiffened, sealed cabinet enables an in-room response below 10 Hz; The superb impulse response is a perfect match with the ultra-fast transient response of the Alcons pro-ribbon systems. The 4 ohms impedance caters for maximum amplifier efficiency. The ultra-slim enclosure design provides for stacking, flying or wall- and ceiling-mounting in even the smallest of spaces; For this, the cabinet is equipped with M10 mounting points.

For full system performance, the CRMS-LFE18sl is to be driven and controlled by the ALC amplified loudspeaker controller, to deliver the most accurate reproduction for even the lowest octaves, to bring the most realistic experience of speech, music and effects.
The integrated factory presets in the drive processor of the ALC offer optimisation settings, as well as VHIR™ processing for perfect phase-matching with an Alcons pro-ribbon system.

The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the CRMS-LFE18sl and ALC, significantly increasing response accuracy and reducing both linear and non-linear distortion to an absolute minimum, regardless of cable length and system impedance.

Typical applications include LFE system for quality-conscious post-production facilities and mastering suites, high-end mix/screening rooms, recording studios and premium home theatres.
