JBL EON15 G2 - Manual (Page 19)

Loudspeaker Placement and Mounting
The following guidelines will help you achieve optimum sound wherever you use your
EON loudspeakers:
Raise the speakers as high as possible. For best results try to get the high frequency horn at
least 2 to 4 feet above the heads of the audience. If the speakers are too low, the people in the
back of the audience will not receive the best quality sound.
Place the speakers between the microphones and the audience. Feedback occurs when the
microphones pick up sound from the speakers and “feed” the sound back through the sound
system. If space is limited, point the speakers away from the microphones to reduce feedback.
Locate the speakers away from turntables. Low-frequency feedback occurs when the output
of the speaker is picked up by the tone arm of the turntable and is re-amplified. A heavy, solid
turntable base and shock mounting can also reduce this type of feedback in DJ applications.
Use more speakers in large or highly reverberant spaces. Spreading speakers throughout
these spaces will produce much better sound than trying to compensate with loudness
level or equalization. For very long distances, the use of another set of speakers on a delay
is recommended.
Stand speakers upright for PA - Tilt the speakers back for stage monitoring. Upright stance
provides even coverage over a wide area. EON speakers are also designed with two slanted
positions for stage monitoring applications.
