Special precautions regarding the Beryllium dome tweeter In its solid form, Beryllium is harmless. However, due to its nature, certain special precautions should be observed to avoid exposure to unnecessary risk. · Under no circumstances should the Beryllium dome be subjected to any form of abrasive action. To ensure no accidental damage to the tweeter dome it is advised to carefully replace the magnetic protection grille. · In the unlikely case of damage to the dome, of any form, the supplied piece of adhesive tape should be immediately used to seal the whole front surface of the tweeter. The protective cover should then be replaced and also taped securely in place. You should then inform the dealer from whom you purchased the product so that the tweeter can be removed by a professional and returned to the product distributor for replacement. · If the dome is broken in any way giving rise to loose particles of Beryllium, these should be carefully collected with the use of an adhesive tape and sealed in a zip-top bag to be returned with the tweeter.

We recommend the use of a dry cloth to dust your pair of loudspeakers. If the loudspeaker is stained, then use a damp cloth. Never use any solvents, detergents, alcohol or corrosive products, scrappers or scouring powder to clean the surface of the loudspeaker. Avoid placing the loudspeakers near a heat source. Running-in period The drivers used in the loudspeaker are complex mechanical devices and require an run-in period before they deliver their best performance. They must get adapted to the temperature and humidity conditions of their environment. This breaking-in period depends on the encountered conditions and can last several weeks. In order to shorten this period, we advise you to let your loudspeakers operate for about twenty hours at medium level, playing standard musical programmes, but with a large amount of bass. Once the components of the loudspeakers are completely stabilized, it is possible to enjoy the real performance of your loudspeakers. 03 installation A B C D E 04 installation Positioning The loudspeakers have been engineered to deliver the most faithful sound reproduction, whether they are used for music or home cinema. In order to enhance their performance, to guarantee a high quality of listening, sound image and tone balance, it is important to note the following basic rules. The listening area must be located at the summit of an equilateral triangle whose two other points of insertion are determined by the position of each speaker. Nevertheless it is possible to modify these distances to find an ideal compromise according to the particular disposition of the room (fig. A). Each loudspeaker must be placed at the same height and on the same floor plan. The tweeter should be at the same height as the listener's ear, when the listener is in their usual listening area (fig. B). Avoid placing the loudspeakers too close to the room's corners or walls. This will induce some unwanted room resonance and artificially increase bass response. On the contrary, if the bass level proves to be insufficient, it is possible to move the speakers closer to the walls to adjust the bass level (fig. C). Optimization To please the perfectionists, we shall give an optimum positioning formula : if A is the distance from the boomer centre to the closest wall (floor or wall), B the intermediate distance and C the longest distance (A
