We are pleased to share with you our philosophy: "the Spirit of Sound". These high performance speakers feature the latest technical developments from Focal-JMlab in terms of speaker design, whether it is for high fidelity or home theater systems. In order to (make the most of these speakers) enjoy the maximum of their performance, we advise you to read this user's manual and to keep it carefully so that you can consult it later. The Focal-JMlab guarantee only applies if the enclosed guarantee card is returned to us within 10 days of purchase. 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. Specifications Aluminum / magnesium inverted dome tweeter: inverted dome technology is exclusive to Focal. It allows an optimized energy transfer. Aluminum / magnesium dome with Poron® surround reveals outstanding performances thanks to a more dynamic and softer tweeter. "W" cone (midrange and woofer): technology of "W" composite cone is a Focal patent. "W" means "Verre-Verre", because of the 2 glass leafs affixed to both sides of a structural foam. Profile uses the latest "W" cone's upgrades: new proportioning of glass leaf, new foam thickness. Bended, multi-fold MDF cabinet structure: toughness and optimal damping. OPC® (optimum phase crossover): phase optimization for a precise, natural and stable soundstage and image. Front and rear profiled port tubes: for a vigorous bass reproduction without any distortion effect. Highly efficient acoustic wadding: excellent internal damping, deeper and tighter bass. Stainless steel fixing screws: noncorroding, even in humid climate. Highly reliable input sockets. Decoupling spikes. 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
