The Mini-Rock was incredibly well received at the NAMM 2018 launch packing a real punch with amazing accurate low frequency extension, fast transient response with incredible detail, outstanding stereo imaging and depth.

Crystal Membrane Woofer

The Mini-Rock uses a powerful high quality German built 150mm / 5.9″ double magnet woofer. Using an ingenious Crystal Membrane inverse aluminium cone that is joined to a paper cone in a special gluing process to result in the desired sandwich construction.

This eye-catching surface of the Crystal Membrane is more than just an attractive design feature as this stiffens the cone, 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.

JET 5 50kHz Folded Ribbon Tweeter

The same German built 50kHz folded ribbon tweeter that is used in the Rock and loved by thousands of users is also featured in the Mini-Rock to ensure the same HF sound and consistency.

Sealed Cabinet with Aperiodic Vent

As with all Unity Audio monitors the Mini-Rock is a sealed cabinet design to guarantee phase accurate low frequency information and fast transient response at any monitoring level. In addition the Mini-Rock also features a clever spilt cabinet Aperiodic Vent design which improves low frequency extension whilst retaining accuracy and transients.

Class D Amplification

Two 180 watt Class D amplifiers run both the tweeter & woofer ensuring plenty of headroom coupled with high SPL’s.

Commercial Installation Applications

It also has applications for the installation market providing yoke mounting points and rear speaker Type 50 mounting bracket points.

The new Boulder MK-III will also be available with a DSP input stage 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 all channels, mute, phase, 8 bands of fully parametric EQ, optional limiter protection and presets.

The intuitive GUI is Mac and PC compatible over Ethernet and the DSP PCB also has additional output channels presented to the Boulder rear panel on XLR’s to feed the B.A.B.E, Avalanche or other sub-woofers for example.

Available end September 2018.
