Overview: The THIEL SCS4 is a 2-way loudspeaker that
performs equally well as an excellent full-range stereo pair, surround-sound, or
center-channel speaker. It's coaxially-mounted drivers and aluminum baffle
contribute to the SCS4's outstanding fidelity, making it as comfortable in
demanding music systems as it is playing movie soundtracks or background music.

Driver Technology
Coaxial/Coplanar Driver: The THIEL SCS4 utilizes
Coaxial/coplanar driver mounting for correct time response delivers full-range
performance with vertical, horizontal, shelf, or stand placement. The SCS4 uses
a very low distortion, high output, metal diaphragm 6.5-inch woofer that is
coaxially mounted with a 1-inch, high output metal dome tweeter, the same high
performance tweeter that is used in THIEL's flagship model CS3.7. The woofer's
short coil/long gap, copper stabilized motor system greatly reduces distortion,
and its reinforced metal diaphragm is specially shaped to reduce diffraction of
the tweeter's energy. In addition, the SCS4's unusual coaxial driver mounting
allows great placement flexibility by ensuring that every listener hears the
sound from both drivers at exactly the same time, regardless of where and in
what orientation the speakers are placed.
Crossover Network: The SCS4 delivers complete phase
coherence for exceptional clarity, transparency, and three-dimensional imaging
thanks to its crossover network. The SCS4's crossover is a true first order
acoustic type that provides the utmost in spatial and depth imaging performance
as well as overall realism. This is the only type of crossover that provides
complete accuracy of amplitude, phase, time, and energy, and therefore the only
type that does not distort the musical waveform. Proper application of this
gradual-transition type of crossover requires the use of more expensive drivers
with wider frequency ranges than are required for use with common
quick-transition crossovers but the benefits also include improved uniformity of
the speaker's output in all directions. The SCS4's crossover is meticulously
engineered to achieve extreme tonal neutrality and is constructed with extensive
use of polypropylene and custom polystyrene capacitors.
Time and Phase Coherent: As with all THIEL loudspeakers, the
SCS4 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 in the SCS4is
achieved by utilizing a sophisticated first-order electrical crossover system in
conjunction with unusually wide bandwidth drivers. Time coherence is achieved by
placement of its Coaxial/Coplanar driver on its baffle that is sloped at the
correct angle to cause the sound energy from each to reach the listener at the
same time.
Enclosure Design
Compact Bass Reflex Cabinet: The SCS4 utilizes an aluminum
baffle, doubly-laminated 1-inch cabinet walls, and thick bracing to create an
extremely rigid cabinet to eliminate unwanted resonances. The cabinet plays an
enormously important role in the quality of music reproduction and so the
engineering of the SCS4's cabinet incorporates several innovations that
contribute to the speaker's stunning clarity, its utter tonal neutrality and its
exceptionally realistic imaging. The SCS4's new cabinet design uses a die-cast
aluminum baffle for much greater rigidity in driver mounting and elimination of
cabinet resonances. Combined with doubly-laminated 1-inch cabinet walls, unified
and reinforced with thick bracing, this robust cabinet construction, usually
only found on much more expensive speakers, greatly improves detail, clarity,
and spatial information. The SCS4 is available in real wood Natural Cherry and
Black Ash finishes
Note: THIEL wood cabinets possess a high quality lacquer
finish that is both beautiful and durable. However, any wood finish can be
damaged by excessive moisture, dryness, or direct sunlight. When cleaning
your speakers, avoid using oils, waxes, or polishes that contain silicone.
Grilles: The SCS4's steel grille frame is designed to not produce
diffraction so there is no sonic reason to remove it. If you do need to remove
the grille, pull the grille frame away from the speaker while gripping both
sides (long) of the grille frame.
Connections
Connections: The SCS4's input terminals are located on the
rear of the speaker cabinet. The SCS4 uses binding posts that accept several
types of wire connections (will not accept dual banana plug connectors but
single banana plugs can be used). The input terminals are designed to be easily
tightened by hand or a 1/2 inch nut driver can be used. The speaker's input
terminals are color coded to facilitate that both speakers in a stereo system
are wired in the same polarity for maximum speaker performance. The speakers
should be connected to the amplifier with high quality cable to ensure minimal
loss of power and proper control by the amplifier.
Note: The SCS4 is a very high quality sound reproducer
and will benefit from use with the best associated equipment. Since it is
extremely accurate, it will reveal sources of distortion generated elsewhere
in the system. For example, distortion resulting from poor recordings or
inferior electronics will be reproduced accurately. Also, the quality of the
interconnect cables and speaker cables will significantly effect the
performance of the system
Power Requirements: It is important to have enough power to
play at the level you desire without distortion. If high sound levels are
desired, the SCS41's are designed to be used with amplifiers rated up to 200
watts per channel (into 8 ohms). Since the SCS4 provides a 4 ohm load to the
amplifier, it is important that the amplifier be rated to deliver at least 50
percent more power into a 4 ohm load than it does into an 8 ohm load. The SCS4
is of average efficiency (88dB) and therefore can achieve average output levels
with an average amount of power.
Mounting Options
Speaker Placement: The SCS4 is specifically designed to give
a high level of performance from a variety of room locations and positions. They
can be placed on bookshelves or on stands, and oriented horizontally or
vertically while still providing a degree of realism not usually obtainable
under unusual or difficult placement conditions. Because the SCS4 is
magnetically shielded, it can be placed on or near video displays without
causing picture distortion.
Warranty
Information & Break-In Period
Break-In Period: The SCS4's, like most speakers, require a
period of playing before they perform optimally. The amount of time depends on
how loudly the speakers are played; more time is required if played softly, less
if played loudly. At least 50 hours at moderately loud levels are required
before the speaker is performing near optimum. You should notice even more
improvement after 100 hours of playing.
10 Year Warranty: THIEL warrants every THIEL model
SCS4 loudspeaker against defects in materials and workmanship to the original
owner for a period of ten years from the date of purchase. THIEL will, at no
charge, replace any defective part and make any repairs necessary to ensure its
proper performance when the defective unit is returned to us postpaid. This
warranty does not cover damage due to accident or abuse and is void if the unit
has been tampered with. This warranty is automatic and no registration is
required.
