surround loudspeaker.
INTRODUCTION
EMBRACE sets an entirely new standard for surround channel per-
formance where stunning musical precision and industrial design are
judiciously allied to complement other Revel loudspeakers. With its
striking and sophisticated appearance, EMBRACE hints at its
advanced design from the first glance. But its sculptured lines can
only begin to tell the story of this exceptional surround channel sys-
tem, with its custom-designed drivers, highly functional enclosure,
and flexible, individually optimized networks.
ABOUT THE MANUAL AND WARRANTY
To begin enjoying your EMBRACE speakers, first read and then
perform the instructions in this owner’s manual. Maximum perfor-
mance is dependent on following all instructions described here, as
well as those found in the owner’s manuals of associated components
in your audio system. Save these instructions for future reference.
The Revel EMBRACE surround speaker is covered by a limited
5-year warranty, so save the bill of sale to protect your purchase
and aid in any service-related questions.

transducer, control, and
connection locations.
DESCRIPTION
Each Revel EMBRACE surround speaker uses an 8-inch mica and
carbon-filled co-polymer woofer to reproduce the lower octaves.
Two 4-inch titanium transducers reproduce the very important
midrange frequencies. Two 1-inch textile-dome tweeters reproduce
higher frequencies.
EMBRACE also features a user-selectable control for dipolar or
bipolar dispersion that optimizes the system for any recording for-
mat. When used in dipole mode, EMBRACE offers a new level of
freedom from “localization,” resulting in more theater-like perfor-
mance for film sound, and more natural results reproducing music.
MIDRANGE
One of the keys to EMBRACE performance is the use of two
extraordinary 4-inch (102-mm) mid-frequency transducers. They
feature neodymium motors and titanium domes with an incredible
stiffness-to-weight ratio for resonance-free, wide bandwidth opera-
tion. Their 1.5-inch (38-mm) voice coils are very rare in 4-inch
midrange design, and contribute greatly to EMBRACE’s freedom
from coloration due to compression. The inverted titanium dome
is truly pistonic throughout its bandwidth and is just one of the
technical elements that set this transducer apart from those used in
any other surround loudspeaker.
WOOFERS
EMBRACE’s 8-inch (210-mm) mica and carbon-filled co-polymer
dome bass transducer utilizes a 2-inch (52-mm) voice coil with a
very long winding length. This dissipates heat far more efficiently
than a typical 1-inch voice coil, or even most 2-inch voice coils with

short winding lengths. A copper shorting ring is employed to
decrease inductance and flux modulation. The result is a dramatic
reduction in distortion. EMBRACE’s compression-free operation is
further optimized by its unusually long mechanical excursion.
TWEETERS
The two EMBRACE tweeters have several important design ele-
ments that correspond to their midranges. The 1-inch (26-mm)
textile dome tweeters are coated and have an advanced suspension,
oversized 1-inch voice coils, and a low-distortion magnetic system.
Among the results are increased accuracy and more natural musical
dynamics. Moreover, the EMBRACE tweeter shows virtually no
signs of frequency response change at high output levels (i.e., com-
pression), while still maintaining harmonic distortion levels below
the threshold of hearing.
CROSSOVER NETWORK
Built into each EMBRACE speaker is an individually-optimized
crossover network with the following features:
• An extremely sophisticated variable crossover offers dipole,
bipole, remote, and Dual Drive™ capability.
• Hand-wired filter networks with air-core inductors and film
capacitors are calibrated to match each Ultima EMBRACE
speaker to the reference standard.
• External level controls for the tweeter via calibrated switched
precision resistors, thus maintaining identical response from
both speakers.
• Rear-wall proximity compensation switch for optimum perfor-
mance under varying listening conditions.
CABINET
EMBRACE’s inspiring Revel industrial design uniquely comple-
ments the most refined home interiors. While the cabinet design
offers exquisite appearance, it also contributes to the system’s perfor-
mance. The sophisticated main enclosure and its internal bracing
were designed based on our exclusive knowledge developed from
laser interferometry. The result is an acoustically-inert platform for
the generation of sound waves.
Each cabinet includes an integral wall-mount system. An optional
ceiling-mount version is also available from your Revel dealer.

Figure 3. In this 5.1-channel
system, a pair of EMBRACE
surrounds are shown placed to
the sides of the listening area
with optimum coverage for the
front row. As an option, the
EMBRACE surrounds can be
placed farther back to cover
additional rows of listeners.
PLACEMENT
The EMBRACE surround loudspeakers are extremely flexible. They
may be used in a “5.1” channel system in dipole or bipole mode, or
in a “7.1” channel system in dipole, bipole, or Dual Drive™ mode.
5.1-CHANNEL DIPOLE/BIPOLE PLACEMENT
The most common home theater and multi-channel music system
configuration utilizes a pair of EMBRACE surrounds in dipole or
bipole mode, to the sides of the listening area, as shown in
Figure 3. If most listening will occur in the front row, place the
EMBRACE surrounds to the sides of the front row.
NOTE: Each pair of EMBRACE surrounds has distinct left and right
versions, as denoted by labels on the rear. To insure correct surround
operation, be sure to mount the left speaker on the left wall (as you’re
facing the screen) and the right speaker on the right wall.
If the listening area consists of several rows, place the surrounds to
the sides of the back row (see Figure 3). This avoids placing the
surrounds in front of any listener, at the expense of reduced opti-
mization in the front row.
In a very large room, use two pairs of EMBRACE surrounds, as
shown in Figure 4 (on the next page). Both pairs may be placed to
the sides of the listeners, or one pair may be placed to the sides of
the listeners and the second pair may be placed to the rear of the
listeners, as shown in Figure 5 (on the next page).

7.1-CHANNEL DIPOLE/BIPOLE PLACEMENT
Some multi-channel controllers provide two pairs of independent
outputs to drive two pairs of surround loudspeakers or for use in
Dual Drive™ operation. Several configurations are possible:
• Two pairs of EMBRACE surround loudspeakers may be used in
dipole or bipole mode.
• A pair of EMBRACE surrounds may be used to the sides, along
with a pair of direct-radiator loudspeakers to the rear.
• A pair of EMBRACE surrounds may be used in the Dual
Drive™ mode.
NOTE: Each pair of EMBRACE surrounds has distinct left and right
versions, as denoted by labels on the rear. To insure correct surround
operation, be sure to mount the left speaker on the left wall (as you’re
facing the screen) and the right speaker on the right wall.

EMBRACE SURROUNDS
Both pairs of surrounds may be placed on the side walls, or one
pair may be placed on the sides with a second pair on the rear wall,
as shown in Figures 6 and 7 (on the next page).

placed behind the listening position. The direct-radiator speakers
may be placed either out in the room behind the listeners, or on
or near the wall behind the listeners. Consult your Revel dealer
for advice regarding your particular application.
