Congratulations
Congratulations on your purchase of a Definitive Technology ProSub
Subwoofer. This revolutionary subwoofer utilizes state-of-the-art components,
a non-resonant monocoque cabinet and low diffraction construction in order to
achieve the most lifelike sound possible in your listening room for many years
to come. The ProSub is a compact, high quality powered speaker system
intended primarily for use as a subwoofer in superior quality music or home
theater systems.
This ProSub powered subwoofer incorporates a high current power
amplifier, electronic crossover and precise equalization in order to achieve the
highest possible level of low frequency performance. The amplifier and elec-
tronic crossover are completely self-contained modules which are housed in
the subwoofer. The ProSubs incorporate Definitive’s proprietary PowerField
®
technology, by which the amplifier is specifically engineered in conjunction
with the driver for optimum load matching and power transfer characteristics.
The integrated electronic crossover incorporates high level inputs and outputs
as well as a low level input, precise equalization, continuously variable low pass
filter (between 40 and 150 Hz), fixed speaker level high pass filter (to match
the ProMonitors) and a precision volume control. The tremendous built-in
flexibility allows easy, seamless integration with all main speaker systems and
optimum performance in any room. The crossover incorporates circuitry which
allows for exceptional performance as either a single subwoofer or when two
subwoofers are used.
Our engineers have spent many years in developing this product. To ensure
that you only experience the finest performance possible from your subwoofer,
we encourage you to take a moment with this owner’s manual and familiarize
yourself with the proper installation and setup procedures for your subwoofer.
