Loudspeaker Placement And Suspension

The following guidelines will help you achieve optimum sound wherever you use your EON ® loudspeakers: 

Only experienced professionals should attempt to suspend the speakers. 

For permanent installation applications utilizing the M10 suspension points, JBL Professional recommends the use of three (3) M10 x 1.5 thread pitch forged shoulder steel eye bolts with an 18-20mm threaded shaft, along with fender washers, rated for overhead suspension. Users unfamiliar with safe rigging practices should not attempt to suspend loudspeakers. Please see for more information. 

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 with time delay is recommended. Stand speakers upright for PA – Tilt the speakers back on the side 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.
