True giant killers:

The Boulder MKII 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 MKII’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 MKII. 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.

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.
