We've been busy guys!

Very pleased to announce on gearslutz the new Unity Audio Mini-Boulder 3-way active monitor!

This new model*is our latest addition to the professional range of active studio monitors, available now in either analogue or DSP versions. More product announcements to follow shortly btw!

Big on detail...Small on real estate

As the name implies, it's a smaller version of our dual 8.5" Boulder 3 way, albeit with one woofer instead of two.

This Mini-Boulder has all the full detailed range, performance and finesse of it's Boulder big brother, but in a convenient smaller volume cabinet, and with a lower price tag. As our industry and work environments changes, many professionals these days work from smaller commercial studios or home setups. Even so, they still demand and need a super detailed full range monitor that can be accommodated in a smaller studio, and not break the bank.

The Mini-Boulder*is a 3 way active design sharing the exact same electronics and mid/high frequency drivers from our larger Boulder Mk-III model. These include the following;

Coaxial 5” Mid-Range & Folded Ribbon Tweeter Drive Unit

Our unique and exclusive centrally mounted coaxial MF/HF drive unit is hand built in Germany. It comprises of a 5" ring mid-range drive unit and a centrally mounted JET 5 50 kHz folded ribbon tweeter. The combination provides a reduced stray magnetic field with higher efficiency, improved dynamics and smooth, even frequency dispersion.*

This compact design assures true point source phase accurate delivery across it's entire frequency spectrum from 694 Hz to 50 kHz, eliminating phase rotation and frequency anomalies. The result is exceptional imaging and detail, significantly improved impulse and power control providing much improved dynamic range and an even frequency response and dispersion throughout the listening space. The Coaxial driver can be described as dynamic and detailed with depth and spaciousness over a broad listening area providing exceptional detail to beyond 50kHz.

JET 5 50kHz Folded Ribbon Tweeter

This concentrically located ribbon tweeter uses a unique folded ribbon technology providing a wide, smooth dispersion and a flat frequency response exceeding 50kHz.*

The 50 kHz folded ribbon tweeter, which is also used in the Mini-Rock and The Rock has been highly regarded for years due to its superior impulse control, smooth sound character and incredible detail. Delivering true high-definition sound, the JET 5 tweeter 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.

With the power delivery of the two large Class D amplifier running the two 8.5" woofers alongside the two custom Class A/B amplifiers for the Coaxial 5” mid-tweeter, the Mini-Boulder delivers a life-like sense of scale. Taking any performance in their stride, offering high SPL figures with incredible effortless dynamics and transients.*

Sealed Cabinet Design

Accurate Bass Reproduction

Like all Unity Audio monitors, the cabinet is a sealed enclosure that doesn't rely on a traditional resonate port to deliver low bass frequencies. The advantage of this design philosophy is more 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.*

Superior Transient Response

This approach also guaranties super fast transient reproduction far quicker than conventional ported enclosures allowing the user to hear every detail of a sounds initial attack making decisions about compressor envelopes far easier to judge.
Accurate Frequency Response At Any Level

Another invaluable attribute of the sealed cabinet design is the ability to monitor at extremely low levels without compromising low frequency reproduction which is an issue with other types of cabinet designs. No longer does the user have to monitor at higher monitoring levels to judge the bass correctly. Working for long periods of time at low to moderate listening levels while maintaining a full and accurate picture is all possible with the Mini-Boulder.

Cabinet Construction

To accommodate the large 8.5" / 220mm woofers, the sealed cabinet uses 18mm Baltic Birch plywood and a huge 30mm Corian front baffle with large radius edges to reduce reflection and cabinet resonances. This adds density, mass and rigidity providing a solid and resonant free mounting platform for all the drive units.*


The Mini-Boulder is ideal for a number of critical applications, be it stereo or multi-channel, recording, mixing, mastering, composing. Ideal for smaller rooms that still demand very detailed full frequency range 3 way sound.

Great another monitor to put in my short list

I’ve heard the full size boulders and they are amazing to say the least. It’ll be interesting to see how these compare!!

... are they half the price of the dual woofer?
