Temperature Correction
These SmartSub models contain unique circuitry (patent
pending) that corrects for compression distortion due to
heating of the drivers’ voice coils. Without this correction
subwoofer output levels could decrease by as much as 5 dB
and the response altered at times of high demand. The
correction allows the subwoofer to provide more accurate,
uncompressed and dynamic reproduction.
A thermistor is mounted to the woofer’s voice coil so that
the amplifier can continuously measure the voice coil’s
temperature. Knowing this, circuitry automatically adjusts
both frequency response and level of the signal to accurately
compensate for all effects of temperature on performance.
This compensation ensures that the subwoofer’s response
and sensitivity don’t change with temperature.
Protection from overheating
An automatic shutdown feature is included that protects
the drivers from excessive heat produced by input levels that
are excessively high. By knowing the temperature of the
voice coil at all times, a shutdown is automatically executed
if temperatures ever reach levels that could cause damage.
The unit continues to monitor the temperature and is
automatically restarted when the temperature falls to a safe
level.
Accurate Matching to Main Speakers
Rather than providing generic built-in crossover controls
that can rarely achieve high quality blending of the
subwoofer with main speakers, the SmartSub can be used
when needed with a separate unit, either a dedicated passive
crossover or the universal SmartSub Integrator.
The passive crossovers provide perfectly blended
augmentation of the main speakers, allowing the
combination to provide very accurate reproduction of the
entire sonic spectrum, to below the audible range.
The SmartSub Integrator provides unprecedented ability
to perfectly match any main speakers and provide total
system performance that is as well integrated and balanced as
a full range speaker. This superior performance is achieved by
innovative circuitry (patents pending) that automatically
calculates the ideal subwoofer response to perfectly match
the characteristics of the main speakers. Therefore, instead
of the usual crossover controls that tell the subwoofer how to
perform, the SmartSub Integrator has settings for the
characteristics of the main speakers you are matching, the
configuration of your system and the performance you
desire. This information is then used to automatically
calculate and implement the ideal subwoofer response. In
addition, the unit enables the total system to operate in
either augment or crossover system mode and can control up
to 16 subwoofer units in either mono or stereo configuration.
