3 way active monitor with coaxial midrange-tweeter.

The next active professional monitor following on from the The Rock, is the new Boulder. This shares some of the same interesting material and designs such as a Baltic Birch plywood cabinet but this time 18mm instead of 12mm as used in The Rock. A Corian front baffle is used again like The Rock and bonded to an internal wooden baffle, but the Boulder uses a huge 30mm slab of Corian instead of The Rocks 12mm and with large radius edges to reduce reflection. Like The Rock, this new model will boost true fidelity, fast, accurate detailed sound but with extended bass response, even more detailed mid range and higher SPL's for larger rooms. 

Two 180mm (7'' ) woofers are used, the same woofer model as in The Rock, this will increase low frequency extension and achieve higher SPL's. Each woofer has a 0.2mm aluminium foil chemically bonded to a rigid pulp fibre cone. This reduces harmonic anomalies and permits +/- 15mm of woofer travel producing accurate low bass frequencies. The use of Aluminium bound to a pulp fibre cone insures that the woofer cone will remain symmetrical at all frequencies, producing a long life for the woofer element and full accuracy of the driver through its life. Something few other materials can claim.
