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 "blos-
soming" 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 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.
