Press Release
Alcons Audio announces the CRMS-LFE18sl mkII, a slim-profile reference subwoofer system engineered for the most demanding critical listening environments. Designed to deliver exceptionally accurate bass and subsonic reproduction, the system combines extended low-frequency response with outstanding transient accuracy for a truly immersive listening experience.
Developed with a focus on linearity across its operating bandwidth, the CRMS-LFE18sl maintains precise control over ultra-low frequency transients. At its core is a custom-designed 18” woofer featuring a large motor structure with dual 3” voice coils, enabling extreme excursion capability—up to 10 dB greater than conventional professional 18” transducers
The direct-radiating driver is housed in an internally stiffened, sealed enclosure, delivering an in-room response of below 10 Hz. This configuration ensures an exceptional impulse response, perfectly matching the ultra-fast transient characteristics of Alcons’ proprietary pro-ribbon systems.
Due to the newly-designed form-factor the CRMS-LFE18sl offers unmatched installation flexibility. With its ultra-slim cabinet depth of only 33 cm (13 inches), combined with integrated M10 mounting points, stacking, flying, wall-, or ceiling-mounting is supported – even in space-restricted environments.
For optimal performance, the system is exclusively powered and controlled by an Alcons ALC amplified loudspeaker controller. Factory presets and VHIR™ processing ensure precise phase alignment with Alcons pro-ribbon systems, while the 4-ohm impedance maximizes amplifier efficiency.
Incorporating Signal Integrity Sensing™ (SIS™) pre-wiring, the CRMS-LFE18sl compensates for cable and connector influence between the subwoofer and SIS™ featured amplified loudspeaker controller. This results in significantly improved response accuracy and minimized distortion, regardless of cable length or system impedance.
Philip “Dr. Phil” de Haan, head of Alcons Audio R&D: “the CRMS-LFE18 has always been the tactile foundation of our studio and residential solutions. The custom-designed 18” woofer in the sealed cabinet significantly extends the low frequency response of the wide-bandwidth pro-ribbon systems. Now with the new sl form-factor, this outstanding fundamental performance can be achieved in more space-conscious applications.”
The CRMS-LFE18sl is ideally suited for use as an LFE system in high-end post-production facilities, mastering suites, premium screening rooms, recording studios, and reference-grade home cinemas—where absolute accuracy and realism in low-frequency reproduction are essential.
