Description

The new Boulder MK-III 3-way active monitor supersedes the MK-II model and continues to build on this revered monitor, further redefining expected levels of sonic performance and accuracy for this truly world-class monitoring system.

Like the critically acclaimed MK-I & MK-II, the new MK-III boast's a fast, accurate detailed sound and prodigious extended bass response, and delivers even greater levels of SPL to fit into any critical listening environment or scenario.

New MK-III Features

  • 2 x New 8.5" / 220mm Crystal Membrane Woofers.
  • 2 x New 300 watt Class D amplifiers inc dedicated PSU for woofers.
  • Crystal Membrane 8.5" / 220mm Woofers
  • The eye-catching surface of the precision built German Crystal Membrane is more than just an attractive design feature. The Crystal Membrane woofer construction uses Aluminum-Sandwich AS Technology. The crystal-shaped inverse aluminium dome is joined to the paper cone in a special gluing process to result in the desired sandwich construction. Resembling the surface of a large crystal, the aluminium-foil stamping stiffens the aluminium dome, diminishing resonances and minimizing 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. The wide, double-asymmetrical rubber surround of the 220m woofer can handle up to ±20 mm excursions for truly prodigious volume and lowest distortion, a unique engineering achievement for a driver of its size.
Amplification - Class D & Class A/B with two separate power supplies
Regarded as easily rivalling many larger and more costly monitoring systems, the new MK-III is now fitted with 2 x 300 watt Class D amplifiers with their own separate power supply specifically for the 2 x Crystal Membrane woofers. The Boulder MK-III still retains it's two original discrete custom Class A/B amplifiers with their own dedicated power supply for the Coaxial X-Jet mid-range / ribbon tweeter.

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

X-JET Coaxial Mid-Range & Folded Ribbon Tweeter Drive Unit
The unique and exclusive centrally mounted Coaxial unit which is hand built in Germany comprises of a 5" ring mid-range drive unit and a centrally mounted JET5 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 X JET 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 Folded Ribbon Tweeter

This concentrically located JET5 ribbon tweeter uses a unique folded ribbon technology providing a wide, smooth dispersion and a flat frequency response exceeding 50kHz.

The precision German built JET 5 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, lo
