Surround Loudspeaker Placement; Suggested Surround Speaker Placement (Fig. 11) - HHB CIRCLE STUDIO MONITORS Operating Instructions Manual

SURROUND
LOUDSPEAKER PLACEMENT
• The loudspeaker arrangement for surround sound
monitoring may comprise three front channels
and two surround channels, each placed upright
on stands an equal distance from the listening
position.
• A sub-woofer is often used to improve the
system's low frequency response. A typical setup
may consist of five HHB Circle 5 loudspeakers
with a Circle 1 sub-woofer.
• Ensure that all five loudspeakers are positioned
at the same height - ideally, this will be so that
the tweeters are level with the listener's ears.
• Due to the consistent sound quality of the HHB
Circles, it is possible to mix Circle 5s and Circle
3s in the same surround setup. The front three
speakers, left, centre and right, may be Circle
5s, with a pair of Circle 3s used for left surround
and right surround.
• Widely used in films and pop music, extreme low
frequency effects, as produced by the HHB Circle
1, are often felt rather than actually heard.

the loudspeakers should always be the same. If
the listener is at the centre point of an imaginary
circle, the speakers should all lie on the circle's
circumference.

loudspeakers - this circular diagram is merely
intended as a guide. In fact, many recording and
mixing studios have their surround loudspeakers
mounted on moveable trolleys, enabling each
client to place them in their preferred position.
