Recently CEDIA Award nominee Blackroom and home cinema specialist Pulse Cinemas both integrated the CRMS-LFE18sl subwoofer in their new demonstration rooms. The CRMS-LFE18sl is a slim-sized reference subwoofer system for very demanding listening applications, delivering an accurate bass and sub response for a maximum quality audible and sensible performance.
As part of the Cinema Reference Monitor System group of solutions, 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.
Phil “Dr. Phil” De Haan, head of Alcons R&D: “when we took out the CRMS system from our C-series, to form its own CRMS series, we also wanted a series-dedicated LFE system. Solid, fundamental sub bass reproduction caters for the true impact of a movie experience; The response of the lowest octaves should be tight, accurate and powerful. With that in mind we developed this new 18” transducer from the ground up. The CRMS-LFE18sl is conservatively rated in our specification sheets, as we do not include the extreme excursion capability in the output rating.“
The direct-radiating transducer mounted in the sealed cabinet enables an in-room response below 10 Hz. The driver is pre-wired for the Signal Integrity Sensing™ compensating circuit to deliver the most accurate reproduction for even the lowest octaves.
For full system performance, the CRMS-LFE18sl is to be driven and controlled by the ALC amplified loudspeaker controller, Alcons’ proprietary drive unit with system-dedicated processing and amplification.
The Signal Integrity Sensing™ circuit on board the Sentinel 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 (long) cable length and (low) system impedance.
Thus, with SIS™, the 4 ohms speaker impedance caters for maximum amplifier efficiency, with ample output from lower-rated Sentinels, without any compromise on performance.
The integrated factory presets in the drive processor of the ALC offer system optimisation settings, as well as proprietary VHIR™ processing for perfect phase-matching with an Alcons pro-ribbon system.
The ultra-slim, internally-stiffened enclosure features Alcons space-economic design, well-known from the C-series cinema solutions. With a 27,5cm/10.8” depth and M10 mounting points, the system can be stacked, flown, wall- or ceiling-mounted in even the smallest of spaces.
Phil concludes: “The super-fast impulse response and ultra-low distortion of the CRMS-LFE18 is a perfect match with the Alcons pro-ribbon systems and extends the Alcons CRMS-series to ultra-wide band reference monitor system. The series is finding its way to post-production studios and mastering suites, high-end mix/screening rooms and premium home theatres worldwide. For us, a testament of the wide range of applications where our acoustics, transducer, amplification and processing technologies deliver a 1:1 reproduction of the original sound source. Or as we put it: “one reference, one experience.” For more info: www.crms.info and www.alconsaudio.com
