[. . . ] uNPACKING 1 After opening the top carton flaps, fold the carton flaps right back, remove the cardboard sheet, the bag of accessories and the foam half-shells protecting the speakers and the front grille. These speakers are very heavy, so 2 persons minimum are required to unpack and re-pack them. If «d» is the distance between the two speakers, this distance must be higher than 5 ft (1. 5 m) and the two speakers must be at equal distance from the listening area which forms with them an equilateral triangle. The speakers should be located so that their diffusion follows the longest dimension of the room. Generally speaking it is better to avoid putting the speakers in the corners of a room as this amplifies the low frequencies and tends to enhance the room resonances. If possible it is better to place the speakers at least 8 inches (20 cm) from the walls. Moreover, in order to obtain a more accurate frequency response, it is recommended to raise a compact speaker from 12 to 16 inches (30 to 40 cm) above the floor by placing them on stands. The tweeters of the speakers must be roughly at the same height of the listener's ear when the listener is in sitting position. No solid object or piece of furniture should be placed between the speakers and the listener. An effect of mask, even partial disturbs completely the sound reproduction as it attenuates the high frequencies and also, in most cases, the midrange frequencies. Unless designed for this application, bookshelf placement will alter the frequency response of the speaker, especially in the low frequencies. If a bookshelf location cannot be avoid, the speaker should be set up to minimize various resonance, and the visible part of the grille must be outside the niche. The Egea 3 and Iroise 3 models are delivered with a set of decoupling spikes3. These accessories are to be screwed in the inserts on the base of the speakers after having removed the caps (turn them anti-clockwise). Adjust the height of the spikes by using the M4 Allen key delivered with the speakers. These accessories ensure the stability of the speaker while limiting resonance coming from certain types of grounds like wood floors. It is possible to use them without this front grille, by gently pulling its top end in order to cut off its magnetic link with the magnets to the front panel. To get the grill back in place, position it in front of the speaker and approach it to the front panel until the magnetic link is effective. These operations must be carried out very smoothly in order not to damage prematurely the veneer covering the magnets on the front panel of the speaker4. [. . . ] If the cones move in opposite directions, the resulting out of phase signals will create a perceptible power loss, particularly in the low frequencies. In either case, always connect red or plus to red or plus and black or minus to black or minus. To check that the speakers are in correct phase, switch the system to mono while music is being played. If the amplifier does not have a phase inversion switch, it will be necessary to change over the connections on one only of the loudspeakers. [. . . ]
