Powerful 3-way active studio monitor with a brand new 220mm (8.5”) crystal membrane woofer, new hybrid amplification and DSP controls

The Unity Audio Boulder Mk-III DSP is a critically-acclaimed 3-way active studio monitor with brand new 220mm (8.5") crystal membrane woofer, new hybrid amplification system and DSP.


The Unity Boulder Mk-III boasts a crystal membrane made with an inverse aluminium dome joined to a paper cone using a special gelling process to design the necessary sandwich construction. The aluminium dome is then stiffened with the crystal shape to reduce undesirable resonances and colouration. The result is a tighter low-end with increased power handling and dynamics.


The Unity Audio Boulder Mk-III uses a new hybrid Class D and Class A/B amplification architecture with the former powering both woofers and the latter powers the coaxial-midrange and ribbon tweeter. This new architecture delivers more power while retaining the life-like qualities and superior dynamics that made the Boulder such a studio staple.


A new DSP system replaces the traditional analogue input crossover, offering 24bit/96kHz high-quality operation, ultra-precise 1/10th dB level control on both input and output channels, mute, phase, delay and 8-bands of fully parametric EQ as well as a limiter for protecting the speakers. The DSP is powered via a Mac and PC compatible software and the speaker connects via Ethernet.


In addition to the DSP connections the Boulder Mk-III DSP includes Analogue input and output over XLR to feed either a subwoofer or the Boulder Active Bass Extender (B.A.B.E)


Like the rest of the range, the Boulder Mk-III DSP uses a sealed cabinet, preferred for its accurate bass response, superior transient response and its gradual 12dB per octave roll-off. It is made with 18mm baltic birch plywood with a 30mm Corian front baffle for added density, mass and rigidity to remove any cabinet resonance. Large radius edges are also employed to reduce reflection contributing to the unmistakable quality of this speaker.


This- 3-way active speaker is ideal for near-field and mid-field application, but can be augmented by Unity’s own B.A.B.E or two Avalanche subwoofers for full-range or mult-channel systems in mastering and post-production facilities.
