ABOUT THE I20/I30
Thank you for purchasing the Revel
I20/I30 in-wall Loudspeaker. Designed for
discerning audiophiles, the I20 and I30
offer versatile, easily integrated in-wall
loudspeakers that provide the superior,
uncolored sound that is the hallmark of
Revel loudspeakers. The I20 and I30 repro-
duce realistic, accurate signals with mini-
mal coloration and distortion, making
them perfect complements to Revel Ultima
or Revel Performa front speakers in multi-
channel setups. Proprietary transducers,
sophisticated filter networks, and user
adjustable compensation controls allow
the I20/I30 to achieve remarkable sound
quality and performance befitting the most
demanding home entertainment systems.
The I20/I30 are also perfectly suited as
front and surround speakers in complete
in-wall setups, or as stereo pairs in second-
ary listening spaces, or for integration with
flat screen television home theater installa-
tions. Unlike freestanding loudspeakers,
the I20/I30 occupies no space in living
areas and will not detract from the decor
of the listening room. They are easily
mounted in either pre-existing or new
construction projects.
A critical aspect of loudspeaker design,
transducers convert electrical signals into
audible sounds, profoundly affecting
loudspeaker performance. Combining
superior form and function, the I20/I30
transducers feature a distinctive design
that allows for smoother frequency
response. The cones are constructed with
Organic Ceramic Composite cone material
to reduce distortion, while the spiders are
constructed with a high-strength Nomex
blend with optimized geometry for
increased linearity.
A two-way design, the I20 transducers
effectively cover a broad range of frequen-
cies. A 7.5-inch (190.5mm) woofer delivers
highly refined and dynamically authoritative
low frequencies down to the very lowest
octaves. And, a 1-inch (25.4mm) titanium-
dome tweeter reproduces high frequencies
well above audible levels, with wide disper-
sion for open, airy treble.
A three-way design, the I30, in addition to
its 9-inch (228.6mm) woofer and 1-inch
(25.4mm) tweeter, also features a 3.5-inch
(88.9mm) midrange, which handles critical
mid-band frequencies with natural tonal
balance over a wide operating range.
An advanced midrange (I30 only) motor
structure includes two high-grade
Neodymium magnets placed at the center
of the motor structure, inside the voice coil,
for improved magnetic shielding. Inside
the motor, a black-plated steel shield cup
facilitates heat dissipation for higher power
handling. An integrated aluminum flux-
stabilization ring minimizes modulation
inside the motor’s static gap flux field,
greatly reducing distortion. A copper ring
inside the motor’s gap reduces distortion
even further. Both rings are optimally sized
and placed to maintain constant linear
voice coil inductance with forward and
backward motions.
The I20 has a high-order filter at 2.8kHz.
In the I30, high-order filters at 300Hz and
2kHz optimize loudspeaker on and off-axis
response, helping to ensure smooth octave-
to-octave balance and timbral accuracy.
The I20/I30 feature gold-plated binding
posts that accommodate two connection
methods, while separate High Frequency
Tilt, Low Frequency Boundary
Compensation, High Frequency Level and
Listener Axis controls compensate for less-
than-ideal listening room acoustics and
loudspeaker placement.
Since 1996, Revel has stood at the forefront
of loudspeaker design. Backed with Harman
International’s extensive research and
design facilities, the Revel I20/I30
Loudspeakers benefit from cutting-edge
tools such as a multi-channel listening lab
