8• Ideally, 3 Series MkII Studio Monitors should be placed on suitable speaker stands, rather than on thework surface. This will reduce resonance and deterioration of low frequency performance caused by thespeaker’s mechanical coupling with the work surface.• For optimum imaging, the left and right speakers should be placed symmetrically in the room,so each speaker is the same distance from adjacent walls and reflective surfaces.• The speakers should be placed so the position of the listener and the two speakers form an equilateraltriangle. Adjusting the distance between the speakers will affect the quality of bass heard at the listeningposition. You can experiment with speaker placement to find the placement that produces the preferredbass response, imaging, and—when listening to stereo material—produces a strong “phantom center", inwhich vocals and some instruments seem to originate from a point between speakers.• The listening distance can be determined according to your preference, the acoustics of your room, andthe maximum SPL (sound pressure level) you want to hear at the listening position. You can find thespeaker’s maximum SPL at 1 meter in the Specifications section at the end of this manual. Each doublingof listening distance will reduce the SPL at the listening position by as much as 6dB in an acousticallyabsorptive room, but only 3 or 4dB in an acoustically reflective room.LSR310S subwoofer placement: The low frequency driver of the LSR310S is mounted on the bottom panel ofthe subwoofer. Before placing the subwoofer, make sure the position on the floor is free of any large objects thatcan interfere with or damage the woofer.In a stereo system, the LSR310S subwoofer should be placed directly on the floor, located between the leftand right speakers. In a surround sound system, the subwoofer can be located between the left and center orbetween the right and center channel speakers. The distance of the subwoofer from the listening position canbe adjusted to produce the optimum bass in the system. Placing the subwoofer close to a wall or in a cornergenerally will increase the amount of bass heard in the room. Experiment to determine the Subwoofer placementthat produces the best balance and quality of bass in the system.MIX POSITION MIX POSITIONLEFTSUB / LFERIGHTCENTERLEFTSURROUNDRIGHTSURROUNDLEFTSUB / LFERIGHT
