Unity Audio Unveils Mini-Boulder Studio Monitor

Drawing from its larger Boulder MK-III 3-way studio monitor, Unity Audio has introduced the more compact Mini-Boulder.

Essex, UK (February 28, 2020)—Unity Audio has introduced its new Mini-Boulder active studio monitor and also a variation, the Mini-Boulder DSP.

The Mini-Boulder is a compact version of the larger Boulder MK-III 3 way, featuring one 8” woofer, instead of two. While it is in a smaller volume cabinet, (and sports a similarly lower price tag), the Mini-Boulder 3-way active design shares the same electronics and mid/high frequency coaxial driver as the larger Boulder Mk-III model.

The coaxial 5” ring mid-range driver features a 50 kHz folded ribbon tweeter mounted inside it. The single 8” / 220 mm woofer has a stiff aluminum cone to aid bass precision. The cone has a low loss rubber surround intended to eliminate cone edge resonance and distortion, and the woofer includes a 4-layer high temperature voice coil wound on an aluminum voice coil former.

The Mini-Boulder has a power delivered from a large 300-watt Class D amplifier running the 8” woofer, alongside two custom Unity Audio 100 watt Class A/B amplifiers for the Coaxial mid-range and tweeter.

Like all Unity Audio monitors, the 18 mm Baltic Birch plywood cabinet is a sealed enclosure that doesn’t include a traditional resonate port to deliver low bass frequencies. According to the company’s design philosophy, this allows accurate bass reproduction coupled with better time domain performance. It also reportedly results in a gradual 12 dB per octave roll off, as opposed to a 24 dB ported roll off design. The 30 mm Corian front baffle is bonded to the plywood cabinet forming a solid and resonant free mounting platform for all the drive units.

The Mini-Boulder DSP version features the same DSP hardware and software as used in the other Unity Audio DSP models. It provides a 24-bit/96 k convertor as well as an 8-band EQ, 1/10tth dB gain resolution and preset library/storage. A balanced XLR Aux DSP output rear panel connector allows the possibility of sending audio to a sub-woofer or for other applications via the full DSP processing facilities. The Mac/PC DSP software is controlled over a sealed Neutrik Cat 5 rear panel connector.

The Mini-Boulder, shipping now, runs $6,690 pair while the Mini-Boulder DSP is $7,090 pair.
