BP1.2X & BP2X
Full Range Bipolar Surround/Satellite
Speaker Systems
Owner's Manual
Congratulations
Congratulations on your purchase of a Definitive Technology BP1.2X or BP2X Bipolar Surround/ Satellite Speaker System. These revolutionary loudspeakers utilize state-of-the-art components (homopolymer-coned bass/midrange drivers, moving coil ferrofluid-cooled dome high-frequency radiators, uniphase crossover networks, etc.), a non-resonant monocoque cabinet and low-diffraction construction in order to achieve the most lifelike sound possible in your listening room for many years to come. These compact, high-quality bipolar (equal sound radiates both front and rear) speaker systems are intended primarily for use as a rear or side speakers in Dolby Pro Logic*, Dolby Digital AC-3*, DTS*, Dolby Digital EX*, as well as all 6.1 and 7.1 systems. In addition, they can also be used as front “effects” speakers in multi-channel DSP systems, or as front main left and right speakers.
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 all speakers (left, right, center and rear) be connected in proper phase. Note that one terminal on each speaker (+) is colored red and the other (-) 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 all 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 others.
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.
Positioning the BP1.2X or BP2X in Your Room
For Rear or Side Surround Speakers
The BP1.2X and BP2X are designed to be extremely flexible in terms of their placement when used as surround speakers. They may be used on the side walls, rear walls or in the rear corners of the listening room. When placed along the side walls the speakers should normally be located adjacent to or behind the listening position. The speakers may also be placed near the rear corners of the room or located on the rear wall. If you have your couch or listening position near or against the rear wall, we suggest rear wall placement of the BP1.2X and BP2X with them positioned on either side of the couch and in from the side wall. High placement is preferred; however, midwall or floor placement is certainly acceptable. Normally speakers would be hung on the wall with the input connection plate up against the wall, however, the BP1.2X and BP2X may also be placed on shelves or stands. Of course, experimentation is encouraged to get the best performance in your particular room. As a starting point, we suggest mounting the speakers on the side walls behind the listening position about 3-6 feet off the floor and halfway between the listening position and the rear wall.
When using BP1.2X and BP2X in Dolby EX and other 6.1 and 7.1 systems (which they are perfect for), one pair will normally be located on the side walls as described above and an additional 1 or 2 speakers will be located on the rear wall as described above.
For Front Main (Left and Right) Speakers
Because of their superb performance characteristics, the BP1.2X and BP2X can also be used as a front main system. In this configuration they should normally be placed about 6-8 feet apart approximately at ear level with the inside facing baffle, which has drivers mounted on it, facing towards the listening position.
