Overview: The Definitive Technology ProMonitor 800
loudspeaker 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. The ProMonitor 800 loudspeaker may be used in a
2.0-channel system as a full-range driver, in a 2.1-channel system as a
satellite speaker with a powered subwoofer, or as a satellite speaker in a home
Pressure Coupled Radiator Design: The ProMonitor satellite
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 satellite. 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 ProMonitor 800
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
Drivers: The Definitive Technology ProMonitor 800 features a
4-1/2" BDSS driver coupled to a 4-1/2" pressure-driven planar low-frequency
radiator, and a 1" pure aluminum dome tweeter.
Break-In Period: The ProMonitor 800 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.
Non-Resonant PolyStone Cabinet: The Definitive Technology
ProMonitor 800 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.
Binding Posts: The ProMonitor 800 is equipped with a pair of
gold-plated, 5-way binding posts to attach your receiver's speaker wire.
Mounting: The Definitive Technology ProMonitor 800
loudspeakers may be placed on a stand or shelf, or mounted on the wall or
ceiling. The ProMonitor 800 features a pedestal foot which allows it to fit
securely and safely 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 800 can 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 mounting bracket (ProMount 80, sold separately), or other
manufacture bracket (sold separately) to hang the speaker on a wall or ceiling.
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.
