Bipolar Design: The Definitive Technology BP-8 is a true
bipolar speaker, containing two complete full-range speaker systems; one on each
side of the cabinet. Definitive's Bipolar technology radiates sound from the
front and the back of the speaker for more life-like sound and spacious imaging
for every listener in the room. Bipolar technology combines the performance
advantages of direct radiating (imaging, focus, localization, and specificity)
and dipolar speakers (spacious, all-enveloping ambience) into one ideal speaker
which is perfect for all multi-channel formats. The BP-8's wide dynamic range,
as well as true high-definition sound quality, combined with its bipolar
radiation pattern results in total immersion in the sound field.
High-Definition Cast-Magnesium Drivers: The Definitive
Technology BP-8 utilizes two 5-1/4 inch high-definition bass/midrange drivers
(one on front-side/one on back-side) for significant performance advantages in
the areas of bass reproduction, lifelike midrange clarity, and dynamic range.
These sophisticated bass/midrange drivers incorporate deeply drawn
mineral-filled polymer cones, combined with butyl rubber surrounds and dustcaps,
high temperature vented voice coils, and massive magnet structures. This
combination of features assures high definition, superb transient response, high
efficiency, high power handling, and extended bass response. In addition, they
are assembled utilizing an aerodynamically designed, magnetically inert,
cast-magnesium basket to minimize internal reflections off the back of the cone
and preserve structural and magnetic integrity under all conditions.
Moving Coil Pure Aluminum Dome Tweeters: The Definitive
Technology utilizes two annealed pure aluminum 1-inch dome tweeters (one on
front-side/one on back-side), suspended by a silk surround and acoustically
loaded by a precisely configured phase plug/lens; engineered to assure perfectly
controlled, absolutely linear movement. This results in smooth extended response
(up to 30 kHz), greatly reduced distortion, improved transient response, wider
dispersion, and notably higher definition. Magnetic fluid damping is
incorporated for ultra high power handling.
Phase-Coherent Linkwitz-Riley Crossover Networks: The
sophisticated Linkwitz-Riley design used in the BP-8 equalizes the drivers for
linear phase and frequency response. This preserves the phase coherence,
transient response, and dynamic integrity of the signal for absolutely lifelike
music and home theater reproduction in your home.
Break-In Period: The BP-8 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, Low-Diffraction Cabinet: The
Definitive Technology BP-8 monocoque cabinet is constructed of high-density
medite with 1" thick front and rear baffles, foam dampening pads, and internal
braces. This virtually eliminates resonant cabinet coloration. The BP-8 also
includes an additional divider/brace panel separating the front and rear
drivers. In addition, the design of the BP-8 reduces diffraction to an absolute minimum by
flush mounting drivers on extremely narrow baffles with radial edges, which are
covered by a frameless grille "sock."
Binding Posts: The BP-8 is equipped with a pair of
gold-plated, 5-way binding posts on the bottom of the cabinet to attach your
receiver's speaker wire.
Applications: The Definitive Technology BP-8 can be used as
a front main or rear/side surround speaker.
- Front: When used as front left and right speakers, the
Bipolar tower loudspeakers can be placed right next to your flat-panel TV
with excellent results or may be separated by a distance greater the width
of the TV. The speakers may be angled in toward the listening position or
left parallel with each other.
- Surround: When used as rear or side surround speaker,
the Bipolar tower loudspeakers may be located on the side or behind the
listeners. When used as a side speaker, locate the BP-8 behind and to the
sides of the listeners. When used as a rear speaker, the BP-8 can be located
6-12" from the rear wall and pointed towards the listener, or placed
sideways on the rear wall with the drivers facing at each other and towards
the side walls.
Placement: The BP-8 is engineered to be easy to position (just 4" to 24" out from the wall) in any
listening room or home theater installation in order to achieve superb sonic
reproduction throughout your room. In addition, a major benefit of the special
driver topology is wide dispersion, which assures a superb panorama of lifelike
sound for every listener in the room wherever you put them.
Adjustable Feet: The
Definitive Technology BP-8 comes with four plastic-tipped feet (installed) for
placing the tower speaker safely on your hardwood floors or tile, and four
spiked-feet for placing the tower speaker securely on your carpet. You can
adjust the feet or spikes to tilt the speakers back (front to back approximately
1/2" to 1" higher than rear) for even better sound. The adjustable feet also
help you level the speaker on uneven flooring. In addition, the BP-8 comes with
a pair of rear-stabilizer feet to help stabilize the speaker even further.
