Owner's Manual
Congratulations
Congratulations on your purchase of the
Definitive Technology BP 10B Bipolar
Loudspeaker System. This revolutionary
loudspeaker utilizes state-of-the-art
components (cast basket homopolymerconed bass/midrange drivers, moving coil
ferrofluid-cooled pure aluminum dome high
frequency radiators, uniphase crossover
networks, etc.), a non-resonant monocoque
cabinet and unique bipolar (front and rear)
radiation in order to achieve the most lifelike sound possible in your listening room
for many years to come.
Please Inspect For Shipping Damage
Each loudspeaker leaves our plant in perfect condition. Any
visible or concealed damage most likely occurred in handling
after it left our plant and should be reported at once to your
Definitive dealer or the shipping company which delivered
your loudspeaker.

Connecting Your Loudspeakers
It is critical for proper performance that both speakers (left and
right) be connected in proper phase. Note that one terminal on each
speaker (the +) is colored red and the other (the -) is colored black.
Please make certain that you connect the red (+) terminal on each
speaker to the red (+) terminal of its channel on your amplifier or
receiver, and the black (-) terminal to the black (-) terminal. It is
essential that both speakers be connected in the same way to the
amplifier (in phase). If you experience a great lack of bass, it is likely
that one speaker is out of phase with the other.
Usually if distortion is heard when the speakers are being driven at loud levels, it is
caused by driving (turning up) the amplifier too loud and not driving the speakers
with more power than they can handle. Remember, most amplifiers put out their full
rated power well before the volume control is turned all the way up! If your speakers
distort when you play them loud, turn down the amplifier or get a bigger one.
“Spiking” Your Loudspeakers
An optional “spiking” kit has been provided should you desire to
“spike” your loudspeakers. “Spiking” your loudspeakers will provide
greater stability when placing your loudspeakers on carpeting and will
also, according to many experts, result in an overall improvement in
sonic performance. Care should be taken when using spikes as they
may cause damage to wooden or other floors which are susceptible to
being scratched. Definitive Technology is specifically not responsible
for damage which may result from the use of spikes.
The spike kit contains 4 spikes. To install,unscrew the plastic guides
on the bottoms of the speakers. Then screw the 4 spikes into the T nuts.
Then (preferably with the help of another person) lift the speaker
upright and lower it down to its exact desired position on the floor. You
must lower the speaker to the exact position you want because once the
spikes are in place you cannot move the speakers sideways on the rug
or floor – this may damage the floor or the speakers. Next, adjust the
spikes so the speaker sits solidly (and does not rock).
Please note that 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.

Speaker Break-In
Your BP 10Bs should sound good right out of the box; however, an
extended break-in period of 20-40 hours or more of fairly loud playing
is required to reach full performance capability. Break-in allows the
suspensions to work in and results in fuller bass, a more open “blossoming” midrange and smoother high frequency reproduction.
Positioning the BP 10Bs in Your Room
It is important, because of the BP 10B’s unique bipolar (front and
rear) radiation pattern, that some simple set-up recommendations be
followed in order to assure optimum performance in your room.
Please remember that although these recommendations are usually
valid, all rooms and listening set-ups are somewhat unique, so do not
be afraid to experiment with the speakers. Remember, whatever
sounds best to you is correct.
In most rooms the speakers should be placed 6 to 12 inches from
the rear wall in order to allow the rear radiated sound to freely reflect
off the back wall. Placement closer to the rear wall will increase the
bass output while placement further from the rear wall will decrease
the bass output.
The speakers should usually be placed 6 to 8 feet apart and kept
away from the side walls and corners. A good rule of thumb is to
place the speakers separated by one half the length of the wall they are
positioned along, and each speaker one quarter the length of the back
wall away from the side wall.
Speakers may be angled in towards the listening position or left parallel with the rear wall. Generally, we recommend angling the speakers in which will result in a somewhat brighter, clearer, more detailed
sound with a more focused central image. Leaving the speakers parallel with the wall will result in a less bright, more diffuse sound. Try to
leave the space on the sides of the speakers as open and as unobstructed as possible so that there will be no interference with the rear radiated sound.
