Thiel CS2.3 User manual

CS2.3
The THIEL CS2.3 reflects our highest standards for
sonic reproduction, regardless of price or class.
• A 3-inch thick baffle, 1-inch thick
cabinet walls, and internal bracing
greatly increase cabinet stiffness. By
reducing unwanted vibration, both
clarity and imaging performance are
improved.
• The baffle’s rounded edges contribute
to very open sound by significantly
reducing edge diffraction.
• THIEL-designed and built drivers
incorporate several innovative design
techniques to reduce diaphragm
resonances, increase output levels, and
lower distortion.

HE 3-WAY CS2.3 INCORPORATES
many of the advanced driver,
enclosure, and crossover design
principles used in larger and more
expensive THIEL models, but does so
at a lower price and in a moderately
sized cabinet. The CS2.3 employs a
1-inch metal dome tweeter coaxially
mounted with a 3.5-inch midrange
driver, and an 8-inch metal diaphragm
woofer, with a passive radiator.
THIEL’s unique Coherent Source
design provides greater realism
The CS2.3’s outstanding performance
is achieved in part by THIEL’s Coherent
Source design technology which
preserves the music’s time and phase
information for much greater realism.
Phase correct crossover design and
time correct driver mounting provide
natural three-dimensional imaging and
greater clarity. The CS2.3’s high
performance also results from our
extremely thorough engineering,
rugged construction, and use of
unusually high quality components.

Woofer
The 8-inch woofer uses a very low distortion short
coil/long gap motor system, damped 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 bass radiator, the
woofer produces
exceptionally clean
bass down to 35Hz.
Tweeter/Midrange Driver
The CS2.3’s most innovative design feature is a
coaxial tweeter/midrange driver where the two
drivers share the same voice
coil. The drivers incorporate a
mechanical crossover to direct
the correct frequencies to each
diaphragm, eliminating the
need for the high frequency
section of the electrical
network. The coaxial mounting
results in improved imaging
and clarity, regardless of
listener postion.
Electrical crossover
The CS2.3 electrical crossover 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.

The CS2.3 tweeter/midrange
drivers are mounted coaxially
and share the same voice coil.
The mechanical crossover is
implemented by the coupling
suspension between the two
diaphragms.
The Thiel CS2.3 is a superb loudspeaker, and an eloquent
testimonial to Jim Thiel’s design expertise and his
company’s manufacturing skills…I recommend it highly.
