IW70/IW90 IN-WALL
LOUDSPEAKERS

Since 1996, the Revel name has stood for the best
in loudspeaker design and performance. Backed by
Harman International’s extensive research and design
facilities, Revel loudspeakers benefit from cutting-edge
development tools such as:

•a multichannel listening lab for double-blind,
position-independent listening tests

•a laser interferometer, which enables detailed driver
and baffle/frame analysis

• multiple large anechoic chambers, which allow for
precise tests and measurements

• finite element analysis, utilized for advanced
loudspeaker modeling

•a stereo lithography apparatus, which helps achieve
extraordinarily tight tolerances

Revel Performa IW70/IW90 in-wall speakers draw upon
the same research, resources and unique perspectives
that put all Revel loudspeakers in a class by them­selves. Revel Performa Series loudspeakers provide
unparalleled value and are known for their standard­setting low coloration and freedom from distortion over
an extraordinarily wide dynamic range.

Performa IW70/IW90 in-wall speakers provide audibly
superior performance – validated by state-of-the-art
Revel listening facilities – that far outclasses comparable
products from competitors.

HIGHLIGHTS

• The IW70’s

7-1/2" (190mm) or

IW90’s

9" (230mm)
woofer with a Micro Ceramic Composite (MCC) cone
produces high output with low distortion.

• The IW90 features a

3-1/2" (90mm) midrange with
an MCC cone for low-coloration, wide-dispersion
midrange reproduction.

• The 1" (25mm) angle-adjustable tweeter, with its
pure-titanium dome and integrated waveguide,
provides optimized response, both on- and off-axis.

• The high-order crossover network features
premium-quality components for exceptionally
accurate timbre reproduction.

• The boundary-compensation switch maintains
accuracy when placed near a secondary boundary
(wall or ceiling).

• The three-position tweeter-level control provides
optimum response, whether used with or without
grilles.

INSTALLATION
CONSIDERATIONS

Loudspeaker fidelity depends on the following factors:

• Loudspeaker accuracy and placement

• Listening-room acoustics

But not all listening spaces can accommodate the
ideal conditions for these two factors. Therefore,
careful attention to the placement of your Revel in-wall
loudspeakers will have the most significant impact on
the general performance of the loudspeakers.

The advanced design features of Revel loudspeakers
allow the Performa in-wall loudspeakers to achieve
the best possible sound quality in any listening space.
Revel loudspeakers also provide an unusually large
degree of adjustment of the sound of the speaker to
compensate for varying applications and room acoustics.
The boundary-compensation switch and high-frequency­level control provide fine-tuning ability, even after the
speaker has been installed.

BOUNDARY-COMPENSATION
CONTROL

The boundary-compensation switch controls the
level of bass output of the speaker to accommodate
the greater reflection of bass caused by a close
secondary wall or the ceiling.

Figure 1: IW70/IW90 control locations

When possible, avoid placing the loudspeakers within
2 feet of an adjacent wall or ceiling. If the loudspeaker
must be placed less than 2 feet from a secondary
boundary (wall or ceiling), turn the boundary­compensation switch to the “On” position.

HIGH-FREQUENCY-LEVEL
CONTROL

The high-frequency-level control allows for fine-tuning
of the tweeter output level. This three-position switch
provides the listener with the ability to adjust the high­frequency range for various acoustical environments.

The high-frequency-level control has three positions:

• Set the high-frequency-level control to the center
“0” position if the speaker will be used with the grille
on. This is the normal setting.

• Set the high-frequency-level control to the “–”
position if the speaker will be used without a grille.

• Set the high-frequency-level control to the “+”
position if an increased high-frequency level
is desired.

LOUDSPEAKER
PLACEMENT

The following general placement suggestions
are accompanied by diagrams for recommended
loudspeaker locations.

LOUDSPEAKER PLACEMENT –
2-CHANNEL STEREO

Before installing the loudspeakers, survey the listening
area, keeping the following points in mind and using
Figure 2 as a guide:

• Place the left and right loudspeakers as close to the
same distance from the primary listening area as
possible, and also at an equal distance from the
side walls. Ideally, the distance between the left and
right loudspeakers should be slightly less than the
distance between them and the primary listening
area. The distance between the left and right
loudspeakers should also be the same distance as
that from the loudspeakers to the side walls.

• When installing in the wall, position each speaker so
that the tweeter is as close to ear level as possible.

Note:
Avoid placing the woofers at the 1/4, 1/2 or
3/4 wall height positions, to prevent low­frequency cancellation.

• Refer to the following “Home Theater” placement
section if you also plan to use the speakers in a
home theater system.
