HHB comm CIRCLE STUDIO MONITORS - Manual (Page 14)

Whether you have a stereo or surround sound
system, correct positioning of loudspeakers in the
room is essential, as this will greatly affect the
accuracy of the reproduced sound. Speakers
radiate sound from all directions and therefore
placing them against walls or on the floor is not
advisable. HHB Circle 5 and Circle 3 monitors are
optimised for use under free-field conditions - so for
the best results, consider the following points
when setting up your loudspeaker system.
• The Circle 5 and Circle 3 loudspeakers should be
placed upright on stands, away from boundaries
to reduce reflections. Do not place them on their
sides, as the response at the crossover
frequency will be less accurate.
• Both speakers should be the same distance from
the listening position.
• The Circle 5 and Circle 3 loudspeakers should be
slightly angled in towards each other, so as to
point towards the listening position, and placed
at a height where the listener’s ears are level
with the tweeters.
• Ideally, the two loudspeakers and the listener
should sit at the corners of a triangle, where all
sides are of equal length:
• The listener should not sit too close to the
speakers, (i.e., within this imaginary triangle),
since the important centre image (sweet spot)
can be greatly affected when listening in this
position.
• The loudspeakers should be placed away from
corners and walls - more than one metre away
(approximately three feet) is ideal - since there
may be unwanted interference patterns caused
by the reflections of the signal from the walls,
which will colour the low and mid frequencies,
giving the impression of extreme bass warmth
and unnatural midrange.
• At these low frequencies, the sound from the
loudspeakers radiates in all directions, and
reflects off any hard surfaces to combine with
the direct sound. At higher frequencies, sound
from the loudspeakers is more directional,
causing less of a problem with interference.
• Avoid placing the Circle 5 or Circle 3 studio
monitors on top of a mixing console, since this
will adversely affect the frequency response.
Some of the sound output will reflect off the
surface of the console, interfering with the direct
sound from the loudspeakers. Instead, position
the speakers on stands slightly behind and above
the console.
