A few marks and scratches on the top of the speakers.

Sonically performing as new.



Closed cabinet design for a more accurate smoother, deeper bass response made from top grade 12mm, 9 ply Baltic Birch rather than cheaper commonly used MDF. An ingenious bracing system has also been designed to stop cabinet flexing.


To add density, mass and rigidity to the design, the front baffle is manufactured from Corian® and then bonded to a plywood baffle.


A new folded ribbon tweeter has been designed which features a new neodymium magnet system, giving higher efficiency, superior linear frequency and phase response along with the smoother, less fatiguing results associated with the use of ribbon tweeters. The frequency response of the tweeter can go as high as 50 kHz, which is how our tweeters superior phase response is achieved.


A 180mm woofer with a 0.2mm aluminum foil is chemically bonded to a rigid pulp fiber cone. This reduces harmonic anomalies and permits +/- 15mm of woofer travel producing accurate low bass frequencies. The use of Aluminum bound to a pulp fiber 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 it's life. Something few other materials can claim.


Rather than pick an off the shelf amplifier Unity Audio has the best amplifier Guru in the business, Esoteric Audio Research designer TIM De Paravicini has created a amp especially for this monitor. A true 100 watt discrete bi-polar low feedback amplifier with custom wound transformers and dedicated LF & HF sections with overload/clip protection, results in very fast and clean, and astoundingly accurate reproduction.




“Since the Rocks introduction just over two years ago we have always looked at improving things and over this period we have been refining various elements and more recently a significant development has come from the shared Low Frequency amplifier design that we use in the new 3 way mid-field Boulder monitor.”


“We altered the feedback loop in the LF amp module and saw significant bass extension, which also made an already very dynamic monitor sound even more dynamic! We decided to try this in The Rock and it produced the same benefits and so The Rock now has a bass response of 33Hz at the -3dB point instead of 50Hz, and of course being a sealed cabinet it has a gentler 12dB per octave rolloff as opposed to a 24dB rolloff with conventional ported designs. It is also possible for existing MK I customers to upgrade to the MK II."
