Loudspeaker Placement
(continued)
• Move the M12s farther from the front
and side listening room walls to
improve stereo imaging and the sense
of spaciousness in the listening space.
• Move the M12s closer to the corners or
walls of the listening room to increase
bass response.
• The M12s can also be flush mounted in
a bookcase or shelf as shown in Figure
8 (below).
CAUTION
Loudspeakers such as the M12, when
placed on pedestal stands, have a high
center of gravity, which may cause
them to fall if tipped or improperly
positioned.To avoid this, anchor the
loudspeaker to the floor and/or wall
using the same procedures and hard-
ware used to anchor bookcases, wall
units, and other furniture. Harman
Specialty Group assumes no responsibility
for improper selection and installation
of hardware or for any personal injuries
or product damages resulting from
improper installation or a fallen loud-
speaker.
LISTENING ROOM ACOUSTICS
Listening rooms have a profound impact
on sound, particularly at lower frequencies.
In fact, listening rooms can dominate
sounds below about 400Hz. Ideally, listening
rooms would include optimized dimensional
ratios to minimize the effects of room
resonances. But in reality, most listening
rooms are not designed to enhance
loudspeaker performance.
The interaction between loudspeakers and
listening rooms is complex, depending on
two important determinants that affect the
loudspeaker and the listener.
1. Surfaces and other boundaries often
cause large peaks and dips in low-
frequency response. These peaks and
dips often range 12dB or more.
2. Standing waves (also known as room
modes or resonances) interact with
both the loudspeaker and the listener,
resulting in large frequency response
errors.
Unfortunately, there is no simple solution
that considers both factors. Even computer
software programs that examine one or
both factors may not calculate proper
primary listening position or loudspeaker
placement values.
