coupled with a pressure-driven planar low-frequency radiator, a pure aluminum
dome tweeter, a uniphase crossover network, and a non-resonant PolyStone cabinet
with low diffraction construction) in order to achieve the most lifelike sound
possible in your listening room. The Definitive Technology ProMonitor 1000s
feature a 5-1/4" BDSS driver coupled to a 5-1/4" pressure-driven planar
low-frequency radiator, and a 1" pure aluminum dome tweeter.
Center Channel Speaker: The Definitive Technology ProCenter 1000
video-shielded center-channel speaker utilizes state-of-the-art components (BDSS
driver coupled with a pressure-driven planar low-frequency radiator, a pure
aluminum dome tweeter, a uniphase crossover network, and a non-resonant
PolyStone cabinet with low diffraction construction) in order to achieve the
most lifelike sound possible in your listening room. As much as 75% of a movie's
soundtrack is played by the center-channel loudspeaker making it arguably the
most important speaker in a home theater system. The Definitive Technology
ProCenter 1000 features two 4-1/2" BDSS driver coupled to two side-firing 4-1/2"
pressure-driven planar low-frequency radiators, and a 1" pure aluminum dome
Pressure Coupled Radiator Design: The ProMonitor
loudspeakers provides clear, high-definition sound by pressure-coupling
Definitive's exclusive BDSS technology driver to an equal-sized mid/bass
radiator cleverly placed on the top of the speaker. This technique doubles the
lower-midrange radiating area of the speaker without increasing the size of the
enclosure. The result is a warm and life-like sound.
BDSS Technology: Definitive Technology's Balanced Double
Surround System (BDSS) drivers offers a wide-bandwidth accurate frequency
response, broad dispersion, low distortion, and detail retrieval; so you hear
more the music with greater accuracy and enjoyment. BDSS drivers incorporate the
following design features.
- Balanced Double Surrounds: The speaker's balanced
double surrounds support the cone at two points to provide better mechanical
stability for longer, more linear excursion, and improved damping to
suppress parasitic cone resonance.
- Mineral-Filled Polymer Cone: The loudspeakers feature a
deeply drawn mineral-filled polymer cone engineered using sophisticated 3D
modeling techniques for wide range performance.
- Waveguide: The cone's integrated waveguide smoothes
off-axis response for broad, even dispersion and better imaging.
- High Temperature Voice Coil: The driver's high
temperature, oversized, lightweight vented voice coil offers improved power
handling and quick transient response. The Lengthened voice coil also offers
increased linearity and lower distortion.
- Magnet Structure: The driver's magnetic system is
optimized by finite element analysis to maximize magnetic flux in the gap
for high efficiency and linear excursion.
- Die-Cast Alloy Basket: The die-cast alloy basket
minimizes ringing and vibration while the open area minimizes back wave
Non-Resonant PolyStone Cabinet: The Definitive Technology
loudspeakers use a non-resonant PolyStone cabinet with low diffraction
construction. The speaker cabinet is available in a high-gloss black or white
finish. The speaker's cabinet feature a removable cloth grille.
Connections: Each speaker is equipped with a pair of
gold-plated, 5-way binding posts to attach your receiver's speaker wire.
- Satellite Speakers: The Definitive Technology
ProMonitor 1000 loudspeakers may be placed on a stand or shelf, or mounted
on the wall or ceiling. The ProMonitor 1000 features a pedestal foot which
allows it to fit securely and safe on a stand or shelf. The attached
pedestal foot can be removed to mount the speaker to Definitive Technology's
matching speaker stand (ProStand, sold separately) or to wall-mount the
speaker. The ProMonitor 1000 can also be wall-mounted using the rear-panel
keyhole slot. In addition, there is a 1/4"-20 threaded insert on the back of
the speaker so you can use Definitive Technology's optional
80 or 3rd party wall-mount bracket to hang the speaker on a wall or ceiling.
- Center Channel: The Definitive Technology ProCenter 1000 can be
mounted on a stand or shelf; or even wall-mounted. The ProCenter 1000 has
two threaded inserts (1/4"-20) on the back, which can be used with a pair of
optional Definitive Technology
ProMount 80 or 3rd party wall-mount bracket to mount the ProCenter 1000 on the wall.
Angle Adjustment: The ProCenter 1000 loudspeaker has a
simple built-in device which allows you to adjust the vertical angle of the
speaker. There is an adjustable rubber-foot on the bottom-rear of the speaker
cabinet. when you set the center-channel speaker down, the speaker will lean
back and rest on this foot. By varying how far you screw in-and-out the foot,
you can adjust the vertical angle of the speaker. It is recommended that you aim
the center-speaker so that it aims directly towards the height of the listeners'
Break-In Period: The loudspeakers will sound good right out
of the box; however, an extended break-in period of 20-40 hours or more of
playing is required to reach full performance capability. The break-in period
allows the suspensions to work in and results in full bass, a more open
midrange, and smoother high frequency reproduction.
Overview: The Definitive Technology ProSub 1000 is an
advanced state-of-the-art technology powered subwoofer with a built-in
high-power, high-current amplifier and sophisticated electronic crossover, in
combination with an active front-firing 10-inch high excursion woofer and

quality, powered subwoofer that can be used in your home theater or music
Passive Radiator Design: The ProSub 1000 features a 300-watt
(RMS) amplifier driving a high-excursion 10-inch front-mounted direct-radiating
woofer that is pressure-coupled to an 10-inch low-bass passive radiator on the
bottom of the enclosure. The net radiating area of the ProSub 1000 is 39%
greater than a single 12 inch woofer but with better speed, pitch definition,
PowerField Technology Amplifier: The ProSub 1000
incorporates 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 Definitive ProSub 1000
powered subwoofer incorporates a unique, patented, digitally-coupled infinite
power source amplifier with a high-current direct coupled power supply and
discrete MOSFET output devices to ensure perfect high-definition resolution and
reproduction of the most dynamic program material and demanding sub-bass
transients. Construction quality is absolutely state-of-the-art, with only the
highest quality components used including mil-spec glass epoxy circuit boards
and precision resistors and capacitors for many years of faultless superior
High-Definition Subwoofer: The powerful, high-definition 10"
polymer subwoofer driver is specifically engineered by Definitive Technology to
deliver rock-solid low distortion bass, reaching down to the lowest subsonic
frequencies (18-150Hz), with superior transient response. The special
ultra-stiff, low-mass cone (for super-fast transient response) is joined to a
specially formulated surround and long-throw voice coil and spider. The
ultra-rigid basket is engineered to hold the woofer's massive magnet structure
and large voice coil in absolute alignment. The high temperature voice coil is
made of aluminum wound with triple insulated ultra-pure copper wire and baked in
epoxy for increased power handling.
Non-Resonant Cabinet: The cabinet of a loudspeaker plays a
large part in its sonic performance. Resonance and vibration can add unwanted
distortion as well as drain away important energy from the system. The
Definitive Technology ProSub 1000 powered subwoofer utilizes a monocoque
cabinet, which has been specifically engineered to be totally inert and
vibration free, to ensure you of pure sonic reproduction. Monocoque means that
the cabinet is of a unitized construction where all panels are permanently
joined together into one solid structure. The cabinet walls themselves are
high-density medite fused together by space-age polymer adhesives. The front and
rear baffles are extra thick and the cabinet, itself, incorporates multiple
internal braces to ensure total solidity.
Controls: A complete array of controls allows the ProSub
1000 to be perfectly integrated with any stereo or multi-channel audio system,
and tuned for optimum performance in any room.
- Volume Control: The ProSub 1000 features a convenient
front-side-mounted volume control that makes adjustments fast and easy. This
precision level control allows you to perfectly adjust the volume of the
subwoofer to match your system and room as well as to fulfill your own
personal sonic preferences.
- Variable Low-Pass Crossover: The Definitive Technology
ProSub 1000 powered subwoofer has a continuously adjustable low-pass filter
control which allows you to choose a roll-off of from 40 to 150 Hz for the
high end of the subwoofer. This unique "dual stage" roll-off (24dB/oct) is
extremely steep which ensures perfect blending with your main speakers as
well as eliminating unwanted midrange from the subwoofer. This is especially
important because it gives you much greater flexibility in placing your
subwoofer in your room without being able to hear where it is located.
Connections: The Definitive Technology ProSub 1000 powered
subwoofer has a complete range of inputs and outputs to allow easy and effective
hookup to any system. The ProSub 1000 has a separate direct-in LFE low-level
input. Speaker-level inputs are provided in case you do not have a subwoofer
- LFE Input: The Definitive Technology powered subwoofer
has a low-level direct LFE input for Dolby Digital soundtracks, which
bypasses the crossover network. If you are connecting the subwoofer to an AV
receiver without a dedicated subwoofer or LFE preamp output, but does
features a stereo RCA output, you will need to use a stereo RCA cable along
with an RCA Y-adapter.
- Speaker Level In: The Speaker Level inputs (binding
posts) are designed to be used on receivers or amplifiers that do not
incorporate any RCA type subwoofer outputs. If your receiver is equipped
with an RCA type subwoofer outputs, these speaker level inputs should not be
- Speaker Level Output: The ProSub 1000 also features
speaker level outputs (binding posts), so you can connect your front (main
speakers) through the powered subwoofer. The ProSub 1000 has a built-in
speaker level high-pass crossover preset at 80 Hz (6dB/oct).
Note: When using the LFE input with a receiver that has
an internal x-over you should set the x-over on the sub to 150Hz.
Auto Turn-On Circuit: The powered subwoofer has a special
power circuit which automatically turns the powered subwoofer on when a signal
is fed to the loudspeaker and turns it off when there is no signal present, so
it does not require an on-off switch.
LED Indicator: The red LED on the back panel of the powered
subwoofer will light up when a signal is sensed and the amplifier turns non. It
will automatically turn off with the powered subwoofer, a little while after the
signal is discontinued.
Protection Circuits: The Definitive Technology ProSub 1000
features two protection circuits that ensure that the subwoofer can never be
Integrated/Adjustable Feet: The ProSub 1000 features four
integrated feet with rubber tips so you can place it securely and safely on your
home's floor. Each foot's height is adjustable to help you place the powered sub
on an uneven surface.
Placement: The Definitive Technology powered subwoofer has
been designed to operate at frequencies generally below 150 Hz. Because
low-frequency information in this range essentially is non-directional, your
subwoofer can be located anywhere in your listening room that is most
convenient. Also the continuously variable low-pass filter operate at a very
fast roll-off, ensuring great performance wherever you place the subwoofer.
There are, however, some general rules that you should bear in mind when
locating the powered sub.
- For maximum output the subwoofer should be placed in a corner or against
- Corner placement will increase the subwoofer's efficiency, which in turn
will increase your system's maximum output and improve the dynamic
capability of the subwoofer.
