[. . . ] If the speakers are to be used low in the wall invert the speaker so the treble unit is uppermost. The spacing between them will depend on the size of the room and distance to the listeners. 5m (5ft) and the distance between them should not exceed their distance from the listeners. Having the speakers and listeners approximately at the corners of an equilateral triangle is not a bad rule to follow. [. . . ] Having the speakers and listeners approximately at the corners of an equilateral triangle is not a bad rule to follow. If the speakers are placed too far apart, a hole-in-the-middle effect may become apparent. Too close and the panoramic effect will be lost, accompanied by a reduction in depth information. For Home Theatre Installations, the speakers should not be closer together than the width of the screen and their height should be approximately at centre screen height. Home Theatre Centre Channel Applications Theoretically, the best position for a centre channel speaker is behind the centre of the screen, but this can only be realised when using an acoustically transparent projection screen. In most cases the speaker will be positioned in a laterally central position either directly above or directly below the screen. All other things being equal, choose the position that is nearest ear height. However, if this leads to a below screen position, you should be careful to ensure that the speaker is not too close to the floor (see above) and that the sound will not be muffled by the later placement of furniture. Home Theatre Surround Speaker Applications The sound from surround speakers should be as diffuse as possible. This ensures that the frontal audio image is not distorted by changes of listener position or head movements. Screw, but do not tighten, 4 of the screws provided through the slots in the wall frame into the pilot holes in the pre-mount frame. A certain amount of flexing of the wall frame is allowed to take up unevenness in the wall surface, but do not over tighten the screws as excessive distortion of the frame may impede the fitting of the baffle. Always make sure all the terminal caps are screwed down tight, as otherwise they may rattle. failure to observe correct polarity will result in a loss of bass and vague imaging in a multi-speaker installation. When choosing cable, keep the total electrical impedance (out and back) below the maximum recommended in the specification. Ask your dealer for advice, as the optimum cable will depend on the length required. HF Control The switch on the front baffle provides a boost or cut in the speaker's high-frequency output. Use it to adjust the high-frequency level to compensate for severely off axis positioned speakers or heavy wall coverings (Boost) or speakers positioned in highly sound reflective rooms (Cut). The wall frame has a white semi-matte paintable finish, ready if necessary to be re-finished to match your own decor. (figure 5) All connections should be made with the equipment switched off.

There are two pairs of gold plated terminals at the back of each speaker, one pair to the bass/mid units and one pair to the tweeter which permit bi-wiring or bi-amplification if desired. [. . . ]
