Once the center point between the speakers is obtained by measuring equal distances from the left and right speakers, adjust the distance between the listening position and the speakers, as well as the distance between right and left speakers, so that a precise center image is obtained. These monitors are designed to reproduce the most accurate stereo sound stage when the interior angle between the lines connecting from each speaker to the listener is between 40 to 60 degrees. Additionally, it is ideal that a distance of approximately 50 cm or more is maintained from the left and right walls. The grill may be removed and re-attached as necessary. 7: Maintenance · When doing any maintenance, wipe the surface of the cabinet with a dry cloth to remove dust. Damp cloth or cleaning paper may dull the finish on the cabinet surface. Do not use volatile liquids such as benzene, paint thinner, alcohol, etc, and do not spray insecticide near it. · If dust gets into the grill netting, use a vacuum cleaner to remove it. In doing so, adjust the suction power of the vacuum cleaner so that it does not suction too strongly. · If the surface of the speaker unit becomes dusty, use a soft, dry calligraphy brush or a paint brush to carefully sweep the dust away.
