Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: 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
ProCenter 1000 loudspeaker is ideal for use as a center-channel speaker in
conjunction with Dolby Surround Sound Pro-Logic and Dolby Digital decoding.

Driver Technology
Pressure Coupled Radiator Design: The ProMonitor
center-channel speaker provides clear, high-definition sound by
pressure-coupling Definitive's exclusive BDSS technology drivers to two
equal-sized mid/bass radiators cleverly placed on the sides of the
center-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) driver 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 ProCenter 1000
features 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 voice coil is also lengthened to
increase 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
reflection.
Drivers: 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 tweeter.
Break-In Period: The ProCenter 1000 loudspeaker 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.
Enclosure Design
Non-Resonant PolyStone Cabinet: The Definitive Technology
ProCenter 1000 uses 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 features a removable cloth grille.
Connections
Binding Posts: The ProCenter 1000 is equipped with a pair of
gold-plated, 5-way binding posts to attach your receiver's speaker wire.
Mounting Options
Mounting: 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 brackets (735PMT80, sold separately) or other
manufacture wall-mount bracket (sold separately) to mount the ProCenter 1000 on
the wall.
Placement: The Definitive Technology ProCenter 1000 can be placed
above or below your television.
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' ears.
