feature innovative MRS (Maximum Radiating Surface)
drive units. What’s the big deal with MRS drivers? Well,
for starters they neither look nor behave quite like
traditional piston-type drivers.
First, MRS drivers are rectangular—not round—and
feature light, stiff CMMD Ceramic Metal Matrix diaphragms whose front surfaces are ribbed and indented
for improved rigidity. The rectangular shape means the
drivers disperse well across their narrow axes, yet still
have sufficient surface area to produce authoritative
dynamics. Second, side-by-side pairs of oblong voice

coils power the MRS drivers, supporting them over their
entire operating area. The upshot is a mid-bass driver
that, in essence, offers the lightning fast transient speed
and resolution of a good tweeter, yet also has plenty of
dynamic punch and the ability to handle fairly low
frequencies.
Our comparatively deluxe Cascade test system
consisted of a pair of Model Nine two-way, three-driver
floorstanders, a Model Three C center channel, a pair of
Model Seven floorstanders (essentially two-driver
versions of the Model Nine), and a 300-watt Model Twelve
powered subwoofer. The Twelve, like all higher-end
Infinity subs, features the firm’s RABOS (Room Adaptive
Bass Optimization System) EQ system, which helps the
woofer achieve clearer, smoother in-room bass response.
Add everything up, and the system comes in at $5394.
If, like me, you view speakers as sculptural objects,
then you should know these beauties look like speaker
systems that, say, Calder might have designed.
The Cascades are, hands down, the most visually
appealing surround speakers I’ve ever tested, and
more than a few first-time viewers have reacted to

them with long, low wolf-whistles of
appreciation.
From the outset, the Cascades
impress with two characteristics:
stunning clarity and terrific
surround sound imaging. You’ll
Model Three C Center Channel
notice the speaker’s clarity every
time you put on music recordings
or soundtracks that are rich in
textural details, or that combine
multiple complex voices or sound
effects. I tried Telarc’s The Absolute
Sound SACD Sampler, enjoying in
particular the “Marche au supplice” (March to the Scaffold)
movement from the Järvi/ Cincinnati performance of the Berlioz
Symphonie Fantastique. The
movement combines the dark
humor of low brass and string
passages set against low percussion, with a recurrent march theme
featuring high brass outbursts
punctuated by tympani playing a
march-time beat. It’s the kind of
piece that sounds fabulous when
it’s cleanly reproduced, but that
turns into mush through many
speaker systems. Through the
Cascades, however, the voices of
individual instruments remained
clear, pure and distinct—even
when the going got thick and the
orchestration became complex.
These speakers can disentangle the
contents of complex mixes with the
greatest of ease. Imaging and
soundstaging were excellent, too,

with the Cascades presenting a
wonderfully coherent and enveloping sound-in-the-round listening
experience.
From the perspective of tonal
balance, my one complaint would
be that the Cascade system sounds
a little too lightly balanced,

exhibiting a certain
amount of upper midrange/lower treble
prominence and an
apparent response dip
between the lower
midrange and upper bass.
After much experimentation with subwoofer
crossover frequencies and
level settings I eventually
achieved fairly balanced
sound, but the system
never did match the
easygoing, natural
warmth that, say, the Gallo
Reference A/V system so
effortlessly conveys.
Bass from the system’s
Model Twelve subwoofer
was, after careful RABOS
tuning, quite articulate and punchy.
This woofer does better with pitch
definition than it does with extremely low-frequency extension,
and it is generally so clean that
listeners may be tempted to push it
too hard, leading to some momentary distortion. For best results in
larger rooms, consider using two
Model Twelves.
On movie soundtracks, the
Cascade system’s imaging came
into its own, creating a 360
degree surround sound field
that placed listeners in the
center of the action. Unlike most
surround systems, this one can
create the illusion of sounds
coming from the sides of the
room—as in The Fast and the
Furious: Tokyo Drift, where car
chase scenes sometimes provide
first-person sounds of cars being
struck from the side. I was also
impressed by the Cascade
system’s ability to reveal
dynamic contrasts. The trick is
that the Cascades can play very
loudly without apparent compression yet remain crystal clear
at whisper levels—as in the mur-
mured conversation between
Captain Aubrey and Dr. Maturin
following the opening battle scene
in Master and Commander.
Though not without minor
imperfections, Infinity’s Cascade
system is visually stunning, and
offers superb clarity and imaging.
Dynamic contrasts are beautifully
reproduced, too. If Infinity can find
a way to give the Cascades a
touch more bass extension and
lower midrange warmth, this
system will realize its full potential
as a top-tier performer. TPV
The Last Word
• Awesome clarity and surround
sound imaging
• Excellent dynamic contrasts
• Good bass pitch definition
• RABOS subwoofer EQ really works
• Overly light tonal balance
• Sub and Cascade speakers
could use more bass extension
• RABOS setup is complicated and
time-consuming
