[. . . ] (figure 3) Do not expect the imaging to the sides and rear to be as precise as at the front. Phantom images between the speakers are fairly easy to create with sustained tones, but fricative or percussive sounds can tend to localise more at the speakers. It is also difficult to get an ideal balance between front and surround speakers for more than one row of listeners. For a more diffuse effect, mount the speakers higher and point them along either the rear or side wall. [. . . ] Incorrect connection can result in poor imaging and loss of bass. To bi-wire, remove the links by loosening the terminal caps and use a separate 2- core cable from the amplifier to each pair of terminals. When bi-wiring, incorrect connection can also impair the frequency response. Ask your dealer for advice when choosing cable. Keep the total impedance below the maximum recommended in the specification and use a low inductance cable to avoid attenuation of the highest frequencies. We suggest you retain the packing for future use. All Applications The speaker may be used in either vertical or horizontal orientation. However, vertical orientation offers better horizontal dispersion and is to be preferred in most cases as this leads to a more stable image over a wide listening area. Horizontal orientation can be used with little detriment to the imaging if the speaker is used in the front centre position of a home theatre installation where the listeners are within 15° of the centre line ­ equivalent to 0. Leave at least 10cm clear space between the back of the speaker and the wall behind, to allow the port to operate properly. Fix the 4 self -adhesive pads to the base of the speaker. They give a degree of vibration isolation, especially useful if placing the speaker directly on top of a fairly flimsy television. The flat area on top of the television may be smaller than the base of the speaker, so position the feet accordingly. Home Theatre (figure 2) As a front centre speaker: If using a projection television with an acoustically transparent screen, place the speaker behind the centre of the screen. Otherwise position it directly above or below the screen, whichever is closest to ear level. Align the front of the speaker approximately level with the screen. The inertness of the support used can affect the sound quality of the speaker. Ask your dealer for advice on the best type for your needs. Moving the speakers further from the walls will reduce the general level of bass. Space behind the speakers also helps to create an impression of depth. [. . . ] Adjust the toe-in of the front left and right speakers to get a smooth transition of sounds that pan from one side to the other. adjust the angle of the surround speakers to give the best results with a variety of material. 2-Channel Audio If the central image is poor, try moving the speakers closer together and adjusting the degree of toe-in. If you wish to use an aerosol cleaner, remove the grille first by gently pulling it away from the cabinet. [. . . ]
