• Ideally, 3 Series MkII Studio Monitors should be placed on suitable speaker stands, rather than on the
work surface. This will reduce resonance and deterioration of low frequency performance caused by the
speaker’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 equilateral
triangle. Adjusting the distance between the speakers will affect the quality of bass heard at the listening
position. You can experiment with speaker placement to find the placement that produces the preferred
bass response, imaging, and—when listening to stereo material—produces a strong “phantom center", in
which 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, and
the maximum SPL (sound pressure level) you want to hear at the listening position. You can find the
speaker’s maximum SPL at 1 meter in the Specifications section at the end of this manual. Each doubling
of listening distance will reduce the SPL at the listening position by as much as 6dB in an acoustically
absorptive 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 of
the subwoofer. Before placing the subwoofer, make sure the position on the floor is free of any large objects that
can interfere with or damage the woofer.
In a stereo system, the LSR310S subwoofer should be placed directly on the floor, located between the left
and right speakers. In a surround sound system, the subwoofer can be located between the left and center or
between the right and center channel speakers. The distance of the subwoofer from the listening position can
be adjusted to produce the optimum bass in the system. Placing the subwoofer close to a wall or in a corner
generally will increase the amount of bass heard in the room. Experiment to determine the Subwoofer placement
that produces the best balance and quality of bass in the system.
