System Features
5.1-Channel Speaker System: The
Definitive Technology ProCinema 800 System is a 6-piece home theater system
incorporating 4 identical easy to place satellite speakers for front and
surround channels, a matching center-channel loudspeaker, and a robust powered
subwoofer. The system's components incorporate many of Definitive's technologies
including BDSS drivers, pure aluminum dome tweeters, planar pressure coupled
mid/bass radiators, and a 300-Watt powered subwoofer for clear, high-definition
home theater sound quality.
Pressure Coupled Radiator Design: The ProCinema 800
satellite speakers and center-channel provide clear, high-definition sound by
pressure-coupling Definitive's exclusive BDSS technology drivers to equal-sized
mid/bass radiators cleverly placed on the outside of the cabinet. 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.
Break-In Period: The ProCinema 800 Home Speaker System 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

Note: There is a insert plug included which covers the
hole in the bottom of the speaker which you will see after you remove the
pedestal foot when wall-mounting the speaker.
Placement: When used as front speakers, the ProMonitor 800s
should usually be placed 6 to 8 feet apart and kept away from the side walls and
corners. When used as rear speakers, take care never to locate the speakers
forward of the listeners. The ProMonitor 800s may be angled in towards the
listening position or left parallel with the rear wall according to your
personal listening taste. Normally, angling the speakers in so that they point
directly at the listeners will result in more detail and greater clarity.

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.
Powered Subwoofer
Powered Subwoofer: The Definitive Technology ProSub
800 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 8-inch high excursion woofer and 8-inch
bottom-mounted passive radiator for massive bass with superior speed, control,
and detail. The Definitive Technology ProSub 800 is a compact, high quality,
powered subwoofer that can be used in your home theater or music speaker system.
Passive Radiator Design: The ProSub 800 features a 300-watt
(RMS) amplifier driving a high-excursion 8-inch front-mounted direct-radiating
woofer that is pressure-coupled to an 8-inch low-bass passive radiator on the
bottom of the enclosure. The net radiating area of the ProSub 800 is 27% greater
than a single 10 inch woofer but with better speed, pitch definition, and
control.
PowerField Technology Amplifier: The ProSub 800 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 800 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
performance.
High-Definition Subwoofer: The powerful, high-definition 8"
polymer subwoofer driver is specifically engineered by Definitive Technology to
deliver rock-solid low distortion bass, reaching down to the lowest subsonic
frequencies (20-150Hz), 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 800 powered subwoofers 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 800
to be perfectly integrated with any stereo or multi-channel audio system, and
tuned for optimum performance in any room.
- Volume Control: The ProSub 800 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 800 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 800 powered
subwoofer has a complete range of inputs and outputs to allow easy and effective
hookup to any system. The ProSub 800 has a separate direct-in LFE low-level
input (which bypasses the crossover network). Speaker level inputs are provided
in case you do not have a subwoofer output.
- 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
utilized.
- Speaker Level Output: The ProSub 800 also features
speaker level outputs (binding posts), so you can connect your front (main
speakers) through the powered subwoofer. The ProSub 800 has a built-in
speaker level high-pass crossover preset at 80 Hz (6dB/oct).
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 800
features two protection circuits that ensure that the subwoofer can never be
overdriven.
Integrated/Adjustable Feet: The ProSub 800 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 mot 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
the wall.
- 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.
