The VR12 is a 2-way compact multi-purpose loudspeaker, for both portable and permanent applications. Featuring the Alcons RBN601 ribbon driver (multiple patents pending), the VR12 is ideal for applications where high output, very high fidelity sound reinforcement is needed. Its specifications exceed HiFi standards.

The VR12 features a 6” pro-ribbon driver with “Real-90” horizontal dispersion for MF/HF and a 12” mid-bass driver for LF. The frequency response is 60Hz. up to 20kHz. (+-3dB), with a peak power output of 134dB.

Utmost user flexibility was the main design goal; The asymmetrical enclosure and the 90-degree revolvable wave-guide make the VR12 ideal as compact FOH system, fill-in cabinet as well as (high-power) floor monitor. In installations, this also offers very flexible (ceiling/wall) mounting. The cabinet is standard equipped with 6-position fly-track, standmount adapter and single-stud tilt point.

Because of the fast transient response and the flat “ribbon-famous” frequency response of the RBN601, the VR12 excels in absolute maximum gain-before-feedback; Incomparable with any system on the market.

Remarkable detail of the RBN601, currently world’s most powerful MFHF ribbon driver, is the unique “HempHorn™”; This wave-guide is made of a new combination of composite materials with natural hemp fiber structures. Contrary to the traditional glass fiber horns, the HempHorn™ features the same stiffness as conventional (glass fiber) horns, but is characterized with a much higher internal damping (at same weight). This results in a so-called “inaudible” waveguide, without the well-known “harsh horn sound”.
The HempHorn for the VR12 is available in 90x40 or 60x30 degree configuration.

The VR12 is to be powered by the 2x 1kW. ALC2 (or 2x 2kW ALC4) amplified controller.
The SpeakerDriveProcessing™ circuit of the ALC offers dedicated protection and filtering, with remote system equalizing; By fully utilizing the individual speaker components’ efficiency, this results in dramatically increased headroom SPL. It’s combining the output of an active-filtered system with the amplifier-saving of a passive-filtered system.

The SignalIntegritySensing™ pre-wiring of the VR12 ensures complete cable/connector compensation between VR12 and the ALC controller-amplifier, resulting in a damping factor of 10.000 for very tight and accurate mid and bass reproduction.
In short; Driven by the ALC, the VR12 delivers maximum sound quality with (4dB) increased headroom, without any chance of blown-up speakers.

The system is covered by a 6-years limited warranty.
