Loudspeaker Placement
• For optimal stereo imaging and timbre,
point the F52s almost directly toward
the primary listening position as
shown in Figure 5 (right). The toe-in
angle can be reduced to widen the
soundstage, even to the point at which
the F52s are pointing straight forward.
• Move the F52s farther from the front
and side listening room walls to
improve stereo imaging and the sense
of spaciousness in the listening space.
• Move the F52s closer to the corners or
walls of the listening room to increase
bass response.
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 extension. 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.
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.
