Introducing the new
THIE L CS1.6

T
incorporating several
new innovative design
techniques that greatly improve
performance in a small, floor-
standing loudspeaker. The
36-inch tall CS1.6 delivers a
much purer and more open
upper midrange response
coupled with a sweeter and
smoother high frequency
performance than conventional
two-way models. The new
CS1.6 also offers a very high
90 dB efficiency to work well
with lower amounts of
amplifier power.
Innovative Woofer
and Tweeter Design
Much of the CS1.6’s outstanding
performance is the result of its
new high output, high efficiency
aluminum dome, 1-inch tweeter
and the innovative woofer
diaphragm/voice coil design.
Both drivers incorporate short
coil/long gap, copper stabilized
motor systems to greatly reduce
distortion, employ metal
diaphragms for
very uniform

Loudspeaker
• High performance sound from a small,
floor-standing loudspeaker
• High 90dB efficiency to improve output
capability with lower power amplifiers
• Completely time and phase coherent for
greater realism
• Specially designed, ultra-low distortion
woofer and tweeter
• Magnetically shielded for placement
near video displays
• Beautiful cabinetry, available in a variety of
finishes, integrates well into any room.
• Provides great realism for both
music and movies
Completely Time and
Phase Coherent
As with all THIEL loudspeakers, the
CS1.6 is completely time and phase
coherent for much greater sonic
realism. THIEL’s Coherent Source
technology achieves the elimination
of both time and phase distortions
that cause alterations in the
reproduced musical waveforms of
most loudspeakers. Eliminating
these distortions results in enhanced
realism, clarity, transparency and
immediacy as well as improved
imaging and soundstaging in both
the lateral and depth perspectives.
Phase coherence is achieved by
utilizing a sophisticated first-order
electrical crossover system in
conjunction with unusually wide
bandwidth drivers. Time coherence
is achieved by placement of the
drivers on a baffle that is sloped at
the correct angle to cause the sound
energy from each to reach the
listener at the same time.
24 Years of Innovation

and built award-winning and
critically acclaimed loudspeakers
for the finest
home audio
and video
sound
systems.

design. All-
fidelity and clarity.
Cabinet construction
The compact cabinet is built with a 2-inch thick front
baffle and 1-inch thick cabinet walls for extreme
rigidity to reduce unwanted vibration, improving
clarity and spatial performance. The baffle’s rounded
edges reduce diffraction effects for improved tonal,
spatial, and transient performance, and its sloped
front correctly time aligns the tweeter with the woofer.
The unique slotted bass reflex system reduces
unwanted port noise and grille loading effects.
Finished in the world’s finest woods
The CS1.6 is available in a wide variety of
exquisite, real-wood, laminate, and painted
cabinet finishes, finely crafted to enhance any
home environment.
High output, high efficiency tweeter
The CS1.6 tweeter is a high output, high efficiency
aluminum dome unit with long excursion abilities that
reduce distortion and increase output capability. The
new high frequency driver uses a short coil/long gap
motor system design for low distortion, a copper
sleeve to stabilize the strength of the magnetic field for
reduced distortion, and practically unbreakable lead
wires for increased reliability—features all shared with
THIEL’s more expensive models’ tweeters.
Metal diaphragm, low distortion woofer
The CS1.6’s 6.5-inch woofer uses a much larger than
normal diameter voice coil to greatly extend the
woofer’s bandwidth for improved upper midrange
performance. The large diameter coil distributes its
driving force over a large area of the cone rather than
concentrating it at the center. This coil design coupled
with the woofer’s metal diaphragm increases the cone’s
stiffness and frequency of unwanted resonances for
very clear and open reproduction. The short coil/long
gap, copper-stabilized motor system dramatically
reduces distortion. Equally innovative is the woofer’s
centrally located neodymium magnet that is placed
inside the coil, rather than outside, creating an
inherently shielded speaker to prevent picture
distortion when placed near video displays.

diameter voice coil to drive its aluminum diaphragm. The large diameter places the coil much nearer the edge of the diaphragm and distributes
the force over a three-fold greater area of the cone compared with a small coil which concentrates the force at the diaphragm’s center. The result is
a much stiffer diaphragm that moves unwanted resonances to a much higher frequency for improved upper midrange performance.

The CS1.6’s Innovative Woofer/Voice Coil Design
Achieving excellent
upper midrange
performance presents one
of the greatest challenges
in a two-way speaker
configuration. One the most
innovative solutions to
improving upper midrange
response is the design of the CS1.6’s
woofer diaphragm and voice coil. The 6.5-inch
woofer’s design employs an unusually large, 3-inch
