[. . . ] On delivery, the separate pairs are connected together with high-quality links for use with a single 2-core cable. For single cable connection, leave the links in place and use either pair of terminals on the speaker. ensure the positive terminal on the speaker (marked + and coloured red) is connected to the positive output terminal of the amplifier and negative (marked ­ and coloured black) to negative. Incorrect connection can result in poor imaging and loss of bass. [. . . ] When bi-wiring, incorrect connection can also impair the frequency response. The terminals accept 6mm (1/4-in) spades, bared wire ends or round pins up to 6mm diameter and 4mm banana plugs. When using spades, fit them under the sliding collar.

We recommend you keep magnetically sensitive articles (television and computer screens, computer discs, audio and video tapes, swipe cards and the like) at least 0. Can have a profound effect on how these resonances affect the sound. Try mounting the speakers along a different wall. Even moving large pieces of furniture can have an effect. If the central image is poor, try moving the speakers closer together or toeing them in so they point at or just in front of the listeners (figure 2). If the sound is too harsh, increase the amount of soft furnishing in the room (for example use heavier curtains), or reduce it if the sound is dull and lifeless. Test for flutter echoes by clapping your hands and listening for rapid repetitions. Reduce them by the use of irregular shaped surfaces such as bookshelves and large pieces of furniture. ensure the speakers stand firmly on the floor. [. . . ] Whenever possible fit the spike feet supplied after you have optimised the positioning. They are designed to pierce through carpeting to the floor surface. Initially, screw the lock nuts fully onto the spikes and screw the spikes fully into the threaded inserts in the base of the speaker. If the cabinet rocks, unscrew the appropriate spikes until the speaker stands firmly on the floor and lock them in place by tightening the lock nuts against the base. [. . . ]
