A new, innovative subwoofer from THIEL is planned for early
2002. The new SW1 using SmartSub technology is a high performance
subwoofer system designed to achieve perfect integration with
any main speakers for the most seamless, coherent sound possible.
The subwoofer that doesn't sound like a subwoofer
"The new THIEL SW1 is the most advanced subwoofer ever
for complete sonic integration in home audio and video sound
systems," says THIEL president Kathy Gornik. "SmartSub
technology eliminates the major problems and limitations that
conventional subwoofers have in matching the system's main speakers
and the room. The SW1 is a subwoofer that doesn't sound like
THIEL's patent pending SmartSub technology
The woofer cabinet is a stand alone system for reproducing
the "point one" channel in a home theater system and
can be used with the companion crossover to allow reproduction
of the bass range of the other channels. Both units incorporate
aspects of THIEL's patent pending SmartSub technology.
o Smart-Match Filter: The SmartSub crossover/controller
can be adjusted to automatically match the SW1 to your main speakers,
regardless of brand or type, for accurate and seamless sonic
o Smart-Room Filter: The SW1 can be easily
adjusted to accurately eliminate room interaction problems for
any placement, without microphones or complicated measurements.
o Smart-Power Circuitry: Unique electronic
circuitry corrects for compression distortion due to heating
of the drivers' voice coils for more dynamic and effortless reproduction.
Smart-Match Filter: Solution for main speaker integration
"The SW1 subwoofer takes the guesswork out of subwoofer
crossover adjustments," says designer Jim Thiel. "Rather
than you telling the subwoofer how to perform by setting controls
for crossover frequency, level, and phase, SmartSub circuitry
automatically calculates the ideal settings once you enter information
about your main speakers and system. The result is sonic performance
equivalent to a full-range speaker with extremely high output
Smart-Room Filter: Solution for wall and corner placement
Like any speaker, a subwoofer placed near room walls or in
a corner will produce an uneven response, with some frequencies
over-emphasized and others reduced. Using THIEL's Smart-Room
Filter, the SW1 incorporates easy to use controls-no microphone
or equalizer is needed-to accurately compensate for any subwoofer
placement. The result is the elimination of room boundary problems
for outstandingly balanced and smooth bass reproduction.
Smart-Power Circuitry: Solution for dynamic compression
The large amount of power used in small, high output subwoofers
can produce substantial heating of the voice coils which, uncorrected,
lowers output and alters tonal balance. SmartSub circuitry measures
voice coil temperature and automatically compensates for reduced
sensitivity and response changes.
High output, very low distortion drivers for excellent
low frequency realism
The SW1 uses two very high output, very low distortion 10-inch
drivers. THIEL's innovative short coil/long gap motor systems
achieve extremely low distortion and the drivers use aluminum
diaphragms for outstanding tonal response. 20-pound magnet structures
and special high excursion suspensions allow the SW1 to effortlessly
reproduce the most demanding sources with great realism. The
drivers are powered by an internal 1000 watt high efficiency
switching mode amplifier.
The system is completely modular. Depending upon your sonic
needs, you can use multiple SW1s with only one controller. Also,
all circuitry in the crossover is duplicated for true stereo
to provide better imaging than mono subwoofers. Balanced and
unbalanced inputs and outputs are provided.
The SW1 cabinet's dimensions are 11 inches wide, 20 inches deep,
and 23.5 inches high. The weight is 100 pounds.
