Definitive Technology BP 6B - Manual (Page 2)

It is critical for proper performance that both speakers (left and right) be connect-
ed 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.
Your BP 6Bs 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.
An optional “spiking” kit has been provided should you desire to “spike” your
loudspeakers. “Spiking” your loudspeakers will provide greater stability when plac-
ing 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 bot-
toms 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 con-
trol is turned all the way up! If your speakers distort when you play them
loud, turn down the amplifier or get a bigger one.
