The Rock MKIII DSP 2-way active monitor
New feauture summary comparison
The new Rock MK-III is available shortly and will feature the new 7″ / 180mm Crystal Membrane woofer design as used in the Mini-Rock and Boulder MK-III models.
The Rock MK-III DSP still retains the same sized Baltic Birch sealed cabinet and Corian front baffle as previous versions of the Rock along with the 50kHz JET 5 folded ribbon tweeter.
We are now pleased to announce for the first time in our history the introduction of a DSP Rock version replacing the standard analog input crossover.
This high performance 24bit/96k Burr Brown converter design offers a huge amount of DSP control for the user with precise 1/10th dB level control on the input channel and output channels , mute, phase, delay and 8 bands of fully parametric EQ including various filter types, limiter protection. Plenty of factory and user presets are included such as full 3 way crossover integration for the Unity Audio Avalanche sub-woofer.
The intuitive GUI is Mac and PC compatible over sealed air-tight Neutrik Ethernet connector. The DSP also has an additional output channel presented to the Rocks rear panel on a balanced XLR connector to feed the Unity Audio Avalanche active sub-woofer for example, along with the balanced XLR input connector.
In all other aspects the DSP version is exactly the same specification as the standard analog Rock MK-III model.
The Rock MK-III, like it’s MK-II predecessor 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.
Sealed Cabinet Design
Unlike many near-field monitors, 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.
Folded Jet 5 Ribbon Tweeter
This high frequency driver enthrals with its lightning-fast response and wide dynamic range, offering minimal distortion, lots of headroom and a distinctly wider frequency range than conventional dome tweeters. The results are a transparent and effortless sound image which is non-fatiguing at any level and for long intense monitoring periods.
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. To guarantee repeated accuracy and unchanging quality even with high production capacity, gluing and handling are now executed by two SCARA robots. The folding and fixing of the membrane, however, are executed by hand, since for production steps requiring extreme precision, the manual dexterity of skilled technicians is irreplaceable. Due to continuous improvement, the JET 5 tweeter creates an effortless, airy and resonance-free image up to 50,000 Hz.
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.
The Rock MK-III uses two 180 watt Class D amplifiers one per drive unit which also includes DC protection. The Class D power supply provides switchable 115v-230v operation.
Rocks are ideal in a 2.1 or 5.1 system configuration when partnered with an Avalanche Sub-woofer.
