New design boasts aluminium sandwich' technology
Hardware > Monitors
Unity Audio are now shipping their latest active three-way monitor, the Boulder MkIII. Unity have made a name for themselves with their geologically themed speakers in recent years, gaining a stack of professional users and some very favourable reviews in SOS to boot.
The original Boulder's three-way design was highly praised by Technical Editor Hugh Robjohns in his August 2012 review, saying Bad mixes are revealed very plainly for what they are but, equally, it is easy to hear when youre getting it right too. That is what justifies the monitor tag that many speakers claim, but few deserve.
Its clever coaxial design for mid-range and high-frequency reproduction was also a notable feature.
The new Boulder MK-III three-way active monitor follows the same format but is designed to be faster for a more accurate and detailed sound, with an extended bass response and a higher SPL than even its Boulder MKII predecessor.
One of the most eye-catching features of this redesign is undoubtedly the precision-built German Crystal Membrane cone design. The dual 8.5-inch cones feature so-called Aluminium Sandwich' technology which sees an inverse aluminium-dome glued to a paper cone. The foil stamping stiffens the aluminium dome and, according to Unity Audio, this diminishes resonances and minimises colouration, while improving power handling and dynamics.
Additionally, the voice coil design of the bass drivers results in a frequency response that's extended downwards by almost a full octave - now going down to 36Hz at -3dB.
The Boulder MKIII's amps are also new. While the MKIII retains the Class A/B amps used to power the coaxial X-Jet mid-range / folded ribbon tweeter, Class D amps are also introduced. Specifically, a 2 x 300 watt Class D amplifier is used with its own separate power supply specifically for the Crystal Membrane woofers.
The centrally mounted 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, and eliminates phase rotation, claim Unity Audio.
These high-grade studio monitors are available now for £6495 including VAT$7990 excluding sales tax.
