Before deciding where to place your speakers, survey your room and think about placement, using the illustration
below as a guide.

Avoid placing the speakers near power amplifiers, heat registers or other objects that generate large amounts of heat.
Do not place the speakers in very humid or dusty places.
Do not place the speakers in direct sunlight or where they will be exposed to other strong light.
For best results, place the speakers 6–8 feet (1.8-2.4m) apart. If you place the speakers farther apart than this, angle
them toward the listening position.
The speakers will produce the most accurate stereo soundstage when the angle at the listener between the speakers
is from 40 and 60 degrees.
Position each speaker so that its horn center is pointed approximatelyat ear level.
Generally, bass output will increase as the speaker is moved closer to a wall or corner. For best performance, we
recommend that you place the speakers at least 20 inches (50cm) away from the side walls.
