LEGENDARY INFINITY PERFORMANCE.
ENTIRELY NEW FORM FACTOR.
The popularity of flat-panel plasma and
LCD video displays ought to suggest at
least one certainty about the future of
home audio – tomorrow’s loudspeakers
won’t be the boxy, intrusive instruments
they often are today.They’ll deliver all
the power and realism we’ve come to
expect. But they’ll be thinner and more
elegant than ever before.And the first
of this brave new generation?
Infinity Cascade™
.
Infinity has been advancing the
science of sound for almost 40 years
with breakthrough audio technologies
and landmark loudspeaker systems.
Cascade continues the tradition. With
patent-pending Maximum Radiating
Surface™(MRS™) flat-panel transducers,
Cascade delivers uncompromised
Infinity sonic performance from
strikingly beautiful speakers.
High-definition flat-panel video, meet
high-performance flat-panel audio.

WITH INNOVATIVE FLAT-PANEL
TRANSDUCERS,CASCADE ISMINIMALIST
INLOOK ONLY.
Imagine you’re an audio engineer
in search of a something new –
a dramatically less-intrusive
loudspeaker design.The problem
is that conventional transducer
cones, when coupled with their
motor assemblies, are nearly as
deep as they are wide. And placing
a circular cone in a rectangular
enclosure results in rather a lot
of wasted space in all directions.
Now imagine you’re an audio
engineer at Infinity, a company
with 30 years of experience in
electromagnetic induction (EMI)
transducers to guide your work. If you
could combine the flat, rectangular
diaphragm of an EMI device with the
motor technology of a conventional
loudspeaker cone, you just might
have something.

MAXIMUM RADIATING SURFACE™
TRANSDUCERS.
MRS™flat-panel transducers in
Infinity’s Cascade Series permit
unobtrusive speaker enclosures
that are nearly as thin as they
are narrow. And because the MRS
diaphragm functions much like
a flat piston, Cascade speakers
achieve flat broadband frequency
response and uniform on- and
off-axis dispersion with minimal
breakup, even at high listening
levels.That’s performance that not
even the boxiest of conventional
loudspeakers can surpass.

IT’S NOT EASY BEING FLAT.
The appeal of flat-panel transducers
has never been more obvious, and
the basic technology behind them is
straightforward enough. But earlier
flat panels had performance limitations
in the low frequencies, and were prone
to thermal compression.They were also
expensive, with several transducers
needed for use in high-performance
systems. In developing Cascade’s
MRS transducers, Infinity’s engineers
incorporated new materials and
technologies that have overcome the
drawbacks and deliver significant
performance benefits.
CMMD®DIAPHRAGM.
Optimizing the parameters of
Cascade’s flat-panel diaphragms
presented a serious engineering
challenge. But by reinforcing
Infinity’s patented Ceramic Metal
Matrix Diaphragm (CMMD®) – a
uniquely rigid lightweight material –
with strategic ribs and gussets,
Infinity engineers were able to strike
the perfect balance between electro-
acoustic efficiency and reliability.
DUAL ELLIPTICAL VOICE COILS.
Another flat-panel challenge was
finding a way to uniformly drive as
much of the diaphragm’s radiating
surface as possible.A traditional cone
is only driven by a small voice coil
at its apex, but flat panels require a
completely different approach. Infinity
engineers developed dual elliptical
voice coils for Cascade’s MRS drivers.
With more than six times the voice-coil
contact of a typical cone transducer,
they move the diaphragm much like
an ideal piston, for crystal-clear,
resonance-free operation throughout
the driver’s entire dynamic range.
GREATER DYNAMIC RANGE.
In addition to driving the flat diaphragm
more uniformly, the dual elliptical
voice coils offer another benefit.
The greatly increased surface area
of the coils allows them to dissipate
heat more efficiently, reducing
thermal compression and dramatically
increasing the speaker’s dynamic
range.The result is increased sonic
clarity with reduced distortion.
MORE UNIFORM RADIATION.
The flat pistonic response of Cascade’s
MRS drivers sends a cleaner, more
uniform sound to listeners’ ears than
conventional cones.The geometry of
a cone inherently creates signals of
unequal length with different arrival
times, causing what engineers call
“time domain smear.”Cascade’s signals
arrive together, for exceptional detail
and resolution.
INFINITY MRS
FLAT-PANEL TRANSDUCER CONVENTIONAL CONE
A transducer diaphragm where all points move together and
in phase results in less time domain smear,when compared
to conventional cone transducers.

BEYOND THE BOX.
The first Infinity speaker system
was also the first in the industry
to include a powered subwoofer.
This innovation led directly to the
heightened realism of the home
theater systems enjoyed by movie
lovers all over the world. Now,
Infinity’s Cascade Model Fifteen
and Model Twelve make the
ubiquitous black-cube subwoofer
a thing of the past.
Deep, realistic bass is an
essential element of the
cinematic experience. But it’s
just as essential in duplicating
the experience of a live musical
performance.With the high-
performance, small-footprint
Model Twelve and the even
more powerful and uniquely
thin Model Fifteen, Infinity
delivers authoritative, distortion-
free bass in subwoofers that
are easily integrated into any
music or home theater system.
Deeper, cleaner bass from
room-friendly and more
aesthetically pleasing designs.
It’s a combination that discerning
listeners (and their decorators)
have long been hoping for.
Both the Model Fifteen and the
Model Twelve are also designed
for easy integration into your
listening room, as well as your
décor. Infinity’s proprietary
Room Adaptive Bass Optimization
System™(R.A.B.O.S.
™) allows you
to precisely tune the response
of your subwoofer to the physical
characteristics of your room with
just three simple adjustments.
And a full complement of inputs
and controls makes connection
with any movie or music system
simplicity itself.

FILL YOUR SPACE WITH SOUND,
NOT SPEAKERS.
Design has always been an
Infinity hallmark, and Cascade’s
revolutionary technologies have
given our designers even greater
freedom.The bulky footprint
of the conventional loudspeaker
is gone. (With wall-mounted
models, the footprint disappears
entirely.) Even the powered
subwoofer – that most essential
of Infinity innovations – has
an unexpected new look. Narrow,
elegant and (above all) thin,
Cascade will surround you
with brilliant, captivating sound,
without intruding on your space.
Has there ever been a more
beautiful way to experience the
full excitement of your favorite
movies and music?
