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.
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 homopolymer-
coned 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 life-
like sound possible in your listening room
for many years to come.

Owner's Manual
To reduce the risk of the product inadvertently tipping over, two stabilizer brackets, with mounting
screws, have been supplied. These must be installed in the base of the product, in the slots provided.
Installation Instructions:
Tools required:
Philips screw driver (not supplied)
Parts required:
Two stabilizer brackets (supplied)
Four screws (supplied)
Instructions:
1. Carefully lay the speaker on its front surface.
2. Place one of the stabilizer brackets in the rear slot provided. (Note: Stabilizer bracket will be flush
with bottom of base.)
3. Insert two screws provided and tighten them securely, being careful not to strip out material.
4. Repeat steps #2 and #3 for the other stabilizer bracket.
5. Remove
the two supporting feet closest to the stabilizer brackets and thread them into the brass
insert in the stabilizer brackets
.
6. Carefully return the speaker to the upright position and adjust the glides (supporting feet) to
level the speaker.
Note: If desired, the four glides (support feet) may be replaced and the four spikes provided may be
installed. The four spikes or glides must be fully threaded into the brass inserts on the stabilizer brack-
ets, as well as threaded into the two brass inserts at the front of the speaker enclosure.
Pour réduire les risques que le produit se renverse par inadvertance, deux supports stabiliseurs avec
vis de montage ont été fournis. Ceux-ci doivent être installés sur la base du produit, dans les rain-
ures appropriées.
Procédures d’installation:
Outils requis:
Tournevis étoile (non fourni)
Pièces requises:
Deux supports stabiliseurs (fournis)
Quatre vis (fournies)
Instructions:
1. Coucher soigneusement le haut-parleur sur la face avant.
2. Placer un des supports stabiliseurs dans la rainure appropriée arrière. (Note : le support sta-
biliseur sera égal au bas de la base)
3. Insérer deux des vis prévues à cet effet et serrer de façon ajustée en prenant garde de ne pas
élimer les parois du matériel.
4. Répéter les étapes #2 et #3 pour l’autre support stabiliseur.
5.
Retirer
les deux niveleurs (pieds de support) les plus rapprochés des supports stabiliseurs et visser
les niveleurs, dans l’encolure de cuivre des supports stabiliseurs
.
6. Relever soigneusement le haut-parleur dans sa position fonctionnelle et ajuster les niveleurs
(pieds de support) pour égaliser le haut-parleur.
Note: Les
quatres niveleurs (pieds de support) peuvent être remplacés, si désiré, par les quatres
pointes fournies à cet effet. Les quatres pointes doivent être entièrement vissées à même les encolures de
cuivre des supports stabiliseurs, et celles sur la façade avant du haut-parleur
.

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.
Connecting Your Loudspeakers
“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. Toinstall,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.
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.
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 “blos-
soming” midrange and smoother high frequency reproduction.
Speaker Break-In
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 par-
allel with the rear wall. Generally, we recommend angling the speak-
ers in which will result in a somewhat brighter, clearer, more detailed
sound with a more focused central image. Leaving the speakers paral-
lel 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 unobstruct-
ed as possible so that there will be no interference with the rear radiat-
ed sound.
