Front Baffle & Cabinet by Acoustic Studio Designer Kevin Van Green

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

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 7″ (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.
