The Boulder MK-II

True giant killers

The Boulder MK-II 3-way active monitor redefines expected levels of sonic performance and is regarded as a truly world-class monitoring system. Like the critically acclaimed MKI model, the MK-II’s boast a fast, accurate detailed sound and prodigious extended bass response, and deliver even greater levels of SPL to fit into any critical listening environment or scenario.

Amplification

Regarded as easily rivaling many larger and more costly monitoring systems, The Boulders incorporate four discrete bi-polar low feedback amplifiers from The Rock MK-II. With the power delivery of the custom Class A/B amplifier at their disposal, The Boulders deliver a life-like sense of scale and take any performance in their stride.

Drivers

The Boulders are fitted with two 220mm SEAS custom Aluminum woofers that provide tremendous bass precision down to 32Hz and beyond. The unique coaxial mid-range tweeter driver works as a point source over 7 octaves and delivers linear amplitude and phase independent of frequency. This results in incredibly detailed, accurate imaging you can trust.

"With its superb on-board amplifiers and state-of-the-art drivers, the new Boulder is a truly world-class monitor."

Sealed cabinet

To accommodate the large 220mm woofers the sealed cabinet uses Baltic Birch plywood and a huge 30mm Corian front baffle with large radius edges to reduce reflection and cabinet resonances.

Applications

The Boulders can be expanded with dedicated Boulder Bass Extenders or partnered with an Avalanche Sub-woofer to make a 2.1 or 5.1 system and can even be used with Rocks due to the consistent sonic signature.
