Product description

The MR12 is a reference monitor system, designed for critical sound reproduction in midfield and farfield applications where ultimate analytical fidelity response is required, combined with an exceptionally wide dynamic range.

The 3-way MR12 consists of the Alcons’ proprietary, multiple-patented RBN202 pro-ribbon driver for HF reproduction. Due to the “compression-less” principle and the light-weight moving mass of the pro-ribbon transducer technology, the system has a fully linear response throughout its entire dynamic range with a super-fast transient response; The 500 W peak power input for 200 ms, which is 10x the industry standard) results in a 1:15 RMS-to-peak dynamic range, which means in practice a virtually infinite headroom.

Mounted on the HempHorn™ with patented constant (120-degrees) horizontal directivity, the RBN202  delivers a wide and consistent sound field up to the highest frequencies, which results in a perfect phantom image with true 3D localisation; A very important tool for accurate object placement in immersive systems.

The RBN202 pro-ribbon covers a very wide frequency range to beyond 20 kHz, starting already from 1 kHz, which is well below traditional designs.

Frequencies below 1kHz are taken care of by the custom-designed 5” mid-bass with Active Coil™ for ultra-low distortion MF reproduction; A perfect match with the MHF pro-ribbon technology. The low frequencies are reproduced by the 12” woofer, also featuring Active Coil™, but in a 3” motor structure, combining ultra-low distortion with a very high headroom. The 12” is loaded by the direct-drive ScoopVent™ enabling maximum breathing capacity for the cleanest, non-compressed response, down to the lower octaves.

As integral part of the Alcons eco system, the tri-amped MR12 is to be driven by the ALC amplified loudspeaker controller; Through the integrated VHIR™ processing, 192kHz AES3 digital inputs and audiophile amplifier stages, the ALC makes the MR12 deliver absolute maximum sound quality with utmost operation reliability and flexibility.

Furthermore, this configuration offers also other advantages, such as efficient centralized processing and amplification without difficult accessible electronics; No heat build-up behind a screen, in a baffle-wall or against a ceiling.
