6 ft. (2 in) Minimum 6 ft (2m) Minimum It is best to keep your speaker at least 2 ft. (60cm) from the back wall. More is better in this case. Otherwise, bass frequencies will be unduly reinforced, causing a "boomy" sound. For the most accurate stereo imaging, it is important that both loudspeakers "see" similar boundaries. Coloration from room boundaries is inevitable. Acoustically, the walls-of your room act as flawed mirrors. Having one mirror closer to one speaker will make that speaker sound louder but will also "color" that speaker's output more strongly. Avoid placing one speaker much closer to a side wall than the other. Neither speaker should be closer than 3 ft. (1 m) and, again, the further the better. If possible the two side walls should be similar in nature. A blank concrete wall reflects sound very differently than a plasterboard or glass wall. This will tend to skew the image. The speakers should be no less than 6 ft. (2m) apart. If they are more than 12 ft .(4m) apart or if they are closer than 4.5 ft.(1.46m) from a side wall, they should be toed in slightly to focus the musical stage. Remember that the optimum listening area will be equidistant from the two loudspeakers. Sometimes it is inconvenient to follow the above advice. If so, some experimentation will be necessary to achieve the best results. Some general guidelines are illustrated below. In a symmetrical, rectangular room it is generally best to place the speakers facing the long dimension. If one of the sidewalls is grossly different from the other, best results will usually be gained from placing the speakers facing away from the dissimilar wall. 2 ft. (60cm) Minimum Length 2 ft. (60cm) Minimum 0 In an asymmetrical room, it is generally best to place the speakers facing the asymmetry. Try to keep the walls closest to the speakers at a similar distance. These guidelines are just that. The sound you achieve will also depend on room furnishings, drapery, carpets, and type of construction. Feel free to break these rules if doing so sounds better. Experiment. It is important to us that you be fully satisfied with the performance of your loudspeakers. Turn off your amplifier to prevent short circuits which can damage your system. You should never change any connections without turning your system off. It is important to choose a quality speaker wire to ensure top performance. This is especially true for long wire runs. Specialty speaker cables are available from your dealer for this purpose. Should these be unavailable the chart below should be followed in selecting the minimum, gauge: up to 15 ft (5m) 16 ga. (1.3mm) 15-3011(5-10m) 14 ga. (1.6mm) over 30 ft (10m+) 12 ga. (2.0mm) CONNECTIONS
