even to the point at which the M22s
are pointing straight forward.
• Move the M22s farther from the front
and side listening room walls to
improve stereo imaging and the sense
of spaciousness in the listening space.
• Move the M22s closer to the corners or
walls of the listening room to increase
bass response.
• Set the Placement Compensation
control to Stand Mounted if the M22 is
is placed on stand such as the optional
Performa Pedestal 22 stand shown in
Figures 5 and 6 on the previous page.
For best results, align the tweeter with
the listener’s ears as shown in Figure 6,
with the front of the M22 facing
toward the listener’s head. Refer to the
Performa Pedestal 22 Assembly
Instructions that are included with the
optional pedestal stand for additional
information.
Note
The optional Performa Pedestal 22 Stand
is available at authorized Revel dealers.
CAUTION
When placed on the optional pedestal
stand, loudspeakers such as the M22 have
a high center of gravity, which may cause
them to fall if tipped or improperly
positioned.To avoid this, anchor the
stand to the floor and/or wall using the
same procedures and hardware used to
anchor bookcases, wall units, and other
furniture. Harman Specialty Group
assumes no responsibility for proper
selection and installation of hardware
or for any personal injuries or product
damages resulting from improper
installation or a fallen loudspeaker.
• Set the Placement Compensation
control to Flush Mounted if the M22 is
placed in a bookcase or wall unit as
shown in Figure 7 at the bottom of the
previous page.
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 both
factors may not calculate proper primary
listening position or loudspeaker placement
values.
In most cases, proper selection of the
primary listening position combined with
proper placement of the loudspeaker can
still result in superior performance at lower
frequencies. The difference between superior
and inferior results is often just a small
adjustment of the primary listening position
or loudspeaker placement. Contact an
authorized Revel dealer for assistance.
