Unity Audio has unveiled its new Boulder MK-III 3-way active monitor, delivering a “faster, more accurate and detailed sound” and extended bass response with a greater SPL than its Boulder MKII predecessor.
The new surface of the precision-built German Crystal Membrane resembles the surface of a large crystal. The aluminium-foil stamping stiffens the aluminium dome, diminishing resonances and minimising coloration, while improving power handling and dynamics. The voice coil design of the bass drivers results in an expanded range of the respective drivers by nearly an octave, down to 36Hz at -3dB.
The unique and exclusive centrally mounted compact Coaxial X-JET 5” mid-range driver and 50kHz folded ribbon tweeter design assures true point source phase accurate delivery across its entire frequency spectrum from 694 Hz to 50 kHz, eliminating phase rotation and frequency anomalies.
The compact design across its entire frequency spectrum from 694 Hz to 50 kHz eliminates phase rotation and frequency anomalies.
The MKIII is now fitted with 2 x 300 watt Class D amplifiers with its own separate power supply specifically for the 2 x Crystal Membrane woofers while retaining its two original discrete custom Class A/B amplifiers with their own dedicated power supply for the Coaxial X-Jet mid-range/ribbon tweeter.
The Boulder MKIII also provides a reduced stray magnetic field with better efficiency, improved dynamics and a “smooth and even” frequency dispersion.
