Unity Audio launched their new Mini-Rock 2 way active monitor at this year's 2018 NAMM show. As the name implies, this new addition represents the smallest model in the company's professional active monitor range to date measuring 279mm high , 184 mm wide, 256 mm deep, ( 10.98" high x 7.24" wide x 10.07" deep ).
The cabinet is of course a sealed design like all the models in the Unity Audio range in order to accurately reproduce low frequencies with superior transient response and without any phase/timing anomalies associated with other designs. The Mini-Rock is also the first monitor in the range with the exception of the Avalanche sub-woofer that uses a split dual-chamber cabinet with Aperiodic Vent. This delivers all the benefits of a sealed cabinet such as zero port noise and tight fast accurate bass reproduction. It also significantly increases the bass response available from a smaller cabinet design.
The Mini-Rock cabinet will also have mounting points for third party yokes and brackets for the installation market.
The Mini-Rock shares the same 50kHz folded ribbon tweeter that is used in the larger Rock and the 3 way Boulder * but a new crystal membrane woofer measuring 150mm ( 5-3/4" ) 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 minimizing coloration, while improving power handling and dynamics. The voice coil design of the woofer results in an expanded range of the respective drivers by nearly an octave.
The Mini-Rock uses two 180 watt Class D amplifiers one per drive unit which also includes DC protection. A custom input/crossover has been designed providing a rear panel volume control. The Class D power supply provides switchable 115v-230v operation.
