Unity Audio introduce Boulder MkIII
Posted on: Sunday 1st of July 2018
The new Boulder MK-III 3-way active monitor delivers a “faster, more accurate sound” and extended bass response with a greater SPL than its Boulder MKII predecessor. Resembling the surface of a large crystal, the aluminium-foil stamping of the ‘German Crystal Membrane’ stiffens the aluminium dome, diminishing resonances and minimizing coloration, whilst improving power handling and dynamics. The voice coil design of the bass drivers results in a claimed 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 aims to assure true point source phase accurate delivery across its entire frequency spectrum from 694Hz to 50kHz, eliminating phase rotation and frequency anomalies. The concentrically located JET5 ribbon tweeter uses a unique folded ribbon technology providing a wide dispersion and a flat frequency response exceeding 50kHz.
The MKIII is now fitted with 2×300 watt Class D amplifiers with its own separate power supply specifically for the two Crystal Membrane woofers, whilst 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.
