Introducing the new
THIE L CS2.4
Coherent Source
HE NEW CS2.4 IS THE RESULT
of THIEL’s 25 years of
T
extensive experience in
designing high performance
loudspeakers for home music and
video sound systems. Since 1977,
THIEL’s innovative engineering
has led to significant sonic
improvements in each new model,
resulting in speakers with the
most outstanding performance in
their class.
All-metal diaphragm drivers
The CS2.4 is a three-way system
incorporating all THIEL-designed
and built metal diaphragm
drivers—a 1-inch dome tweeter,
3.5-inch midrange driver, and
8-inch woofer—along with a 7.5 x
11-inch passive radiator. Metal
diaphragms provide much higher
stiffness which eliminates
diaphragm resonances in the
operating range for very clear and
open reproduction.
The CS2.4 drivers also use
unusual short coil/long gap,
copper-stabilized motor systems to
dramatically reduce distortion.
Coupled with the low resonance
diaphragms
and very
high
quality

components,
a very high
level of
clarity and
tonal
accuracy is
achieved.

Completely Time and Phase Coherent
As with all THIEL loudspeakers, the
CS2.4 is completely time and phase
coherent for great sonic realism.
THIEL’s Coherent Source
technology eliminates 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 in
the CS2.4 is achieved by coincident
tweeter/midrange driver mounting
• Very high performance sound from a
medium-sized, 3-way floor-standing loudspeaker
• Specially designed coincident tweeter/midrange
array eliminates the need for a high-frequency
electrical crossover network
• Completely time and phase coherent
for greater realism
• Ultra-low distortion short-coil, long gap, copperstabilized driver motor systems
• Uniform, resistive load improves performance
when used with lower power amplifiers
• Beautiful cabinetry, available in a variety of
finishes, integrates well into any room.
• Provides great realism for both
music and movies
and the placement of the drivers on a
baffle that is sloped at the correct
angle so the sound energy from each
reaches the listener at the same time.
Finished in the world’s finest woods
The CS2.4 is available in a wide
variety of exquisite, real-wood
finishes finely
crafted to
enhance any
home
environment.
We can custom
stain, paint, or
match a cabinet
to your
furniture. Our
Painted Black
option is even
more
affordable.

New coincident driver array
The new CS2.4’s most innovative design
feature is a newly designed coincident
tweeter/midrange driver where the two
drivers’ diaphragms share the same voice
coil. This technique allows for the
elimination of the midrange/tweeter section
of the electrical crossover network as the
drivers incorporate a mechanical crossover.
Along with eliminating the need for two
driver magnet structures, these reductions
allow the CS2.4 to achieve a level of sonic
performance normally reserved for more
expensive speakers. The coincident array
also uses very powerful neodymium
magnets to improve efficiency and a
redesigned magnet venting system to
reduce unwanted resonances.
Electrical crossover
The CS2.4 electrical crossover network
provides completely phase accurate
transitions between drivers to preserve the
recording’s spatial information. The
network utilizes polypropylene and
custom-made polystyrene capacitors, and
low-oxygen copper, air-core inductors for
very low distortion.
Metal diaphragm, low distortion woofer
The CS2.4’s 8-inch woofer uses a very low
distortion short coil/long gap motor system,
powered by a 2.5 pound magnet. The rigid
aluminum diaphragm eliminates resonance
coloration, a special copper pole sleeve reduces
inductance distortion, and a heavy copper ring
maintains an ultra-stable magnetic field. In
combination with the 7.5 x 11-inch bass
radiator, the woofer produces exceptionally
clean bass down to 33Hz.
Cabinet construction
The CS2.4 cabinet is built with a 3-inch
thick front baffle, 1-inch thick cabinet walls,
and internal bracing 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.
Ten-year warranty
THIEL loudspeakers are constructed with
premium components and the highest
quality workmanship. All THIEL speakers
are backed with a 10-year warranty.

crossover is implemented by the coupling suspension
between the two diaphragms. By eliminating the high

normally reserved for more expensive speakers. The
coincident driver mounting results in perfect time coherence
between the tweeter and midrange drivers for improved
imaging and clarity, regardless of listener position.
