Unity Audio The Rock MK-III Active Monitors (Pair)
Like its MK-II predecessor, The Rock MK-III is an incredibly accurate, critically acclaimed 2-way active mixing reference near-field monitor, considered by many professionals to be the reference all others are measured by. Designed for demanding audio professionals spanning a wide range of applications including tracking, mixing and critical mastering applications. The Rock is equally at home sat atop a large-format mixing console or in a high-end studio, a home studio or a mastering facility.
Cabinet Design
The cabinet is a sealed enclosure that doesn’t rely on a resonate port to deliver low-end performance. The advantage of this design philosophy is accurate bass with better time domain performance and a gradual 12dB per octave roll off as opposed to a 24dB roll off with ported designs. The cabinet is made from 12mm, 9-ply Baltic Birch plywood. To add density, mass and rigidity the front baffle is manufactured from 12mm Corian and bonded to the 12mm ply baffle to provide the perfect mounting platform for the drive units.
Jet 5 Ribbon
The JET tweeter was developed to perfection on the basis of the famous Air Motion Transformer by loudspeaker pioneer Dr. Oskar Heil. Its operating principle is based on a concertinaed-foil membrane, driven by a strong magnet system of neodymium rods. This motor drives the air considerably faster than the pistonic motion of a conventional driver, with gains in higher sensitivity and extraordinary dynamics. Due to many additional design changes, including special patented gluing and surface processes, improved new neodymium magnet system, even higher efficiency, higher sound pressure levels and frequency response up to 50 kHz was achieved. The core of the JET tweeter is the folded foil membrane. With a fold width of only 0.84 mm, a major requirement in the JET production is precision.
Crystal Membrane Woofer
A new crystal membrane woofer measuring 180mm ( 7″ ) has been selected. This eye-catching surface of the crystal membrane is more than just an attractive design feature. The crystal-shaped inverse aluminium dome is joined to a paper cone in a special gluing process to result in the desired sandwich construction. The crystal cone aluminium-foil stamping stiffens the aluminium dome, diminishing resonances and minimising coloration, while improving power handling and dynamics. The voice coil design of the woofer results in an expanded frequency range, and driver surround allows for longer cone excursions for truly prodigious volume and lowest distortion, a unique engineering achievement for a driver of its size.
