INTRODUCTION
With its striking and sophisticated appearance, the Revel Ultima
VOICE center-channel speaker hints at its advanced design from the
first glance. The simple, clean lines characterize an exceptional sound
reproduction system defined by custom-designed drivers, individually optimized crossover network, and a highly-functional enclosure.
We created the VOICE speaker to achieve superior performance in
the widest possible range of multi-channel environments. Physically
small enough to be used in modest rooms, it is dynamic enough to
be used in very large rooms. It is equally at home in discriminating
multi-channel audiophile systems or home theater systems.
Moreover, we’ve taken the care to make it as adaptable as possible to
a variety of system placements and the acoustical interactions typically found in multi-channel systems.
ABOUT THE MANUAL AND WARRANTY
To begin enjoying your VOICE speaker, first read and then perform
the instructions in this owner’s manual. Maximum performance 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 Ultima VOICE center-channel 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.

DESCRIPTION
The Ultima VOICE center-channel speaker uses two 8-inch mica
and carbon-filled copolymer woofers to reproduce the lower
octaves. A 4-inch titanium transducer reproduces the very important midrange frequencies. A 1-inch textile-dome tweeter reproduces higher frequencies.
Combined with an individually-optimized crossover network, this
transducer arrangement provides a uniform “listening window” or
area in which the sound varies little. Also, the large woofer size is
used to reproduce center channel information and all its dynamics
without compression.
MIDRANGE
To ensure accurate detail, each VOICE speaker has a 4-inch
midrange that is unique in the following ways:
• The midrange’s radiating surface is made of titanium for true
pistonic behavior throughout its operating range.
• The midrange’s motor system utilizes neodymium magnets with a
stray-flux containment system for shielding near video monitors.
• The cast magnesium frame provides optimum voice coil cooling
and minimum reflections, while offering excellent rigidity.
WOOFERS
To ensure uncompressed dynamic range, each VOICE speaker uses
a pair of 8-inch woofers that are unique in the following ways:
• The woofer’s radiating surface is made of an injection-molded
polymer material with incredible stiffness and internal damping.
• Optimized magnetic circuits to minimize harmonic distortion.

Connectors (with
shorting straps)
• Oversized 2-inch diameter voice coil with flat aluminum wire
offer higher power handling than average-sized coils for greater
accuracy at high volume levels and during extended crescendos.
TWEETERS
Each VOICE speaker also contains a high-performance tweeter
with the following features:
• Optimized tweeter-dome profiles for maximum dispersion,
while eliminating coloration caused by “break-up modes.”
• Linear reproduction with very-low harmonic distortion even at
high output levels for uncompressed sound purity.
• The tweeter utilizes a large voice-coil with an oversized surround
roll. This provides the higher power handling and longer excursion
capability required to reproduce greater uncompressed dynamics.
CROSSOVER NETWORK
Built into each VOICE speaker is an individually-optimized
crossover network with the following features:
• A 3-way, 24 dB per octave crossover at 300 Hz and 2.2 kHz
shapes the on- and off-axis response of each driver and the complete system.
• Hand-wired filter networks with air-core inductors and film
capacitors are calibrated to match each Ultima VOICE speaker
to the reference standard.
• Provision for bi-amplified and bi-wired applications via removable external shorting straps on the gold-plated binding posts.
• External level controls for the tweeter via calibrated switched
precision resistors, thus maintaining identical response from
both speakers for ideal imaging.
• External LF tilt control for speaker placement optimization.
CABINET
The cabinet offers groundbreaking appearance and aids in overall
system performance. The inner enclosure is designed as an acoustically-inert platform for sound-wave generation. Integral top and
bottom panels provide a custom look via available finishes (see
Panel Replacement on page 14) and are internally damped by sandwiched viscoelastic energy-absorbing layers to reduce any sound
transmission effects.

PLACEMENT
Sound quality is heavily dependent on the accuracy of all your
speakers, their placement in the listening room, and the acoustics
of the room itself. Since the VOICE center-channel speaker is
extremely accurate, experiment with the following speaker systems
and placements (Figures 3 through 5) to enhance performance.
NOTE: The VOICE center-channel speaker includes a user-adjustable
placement compensation circuit that tailors the response for a desired
application (e.g., stand mounting, flush mounting, or on top of monitor). See “System Optimization” on page 12 for detailed use on the
PLACEMENT COMPENSATION control.
