Mounting / Suspending EON® Speakers

EON speakers are designed for portable applications in which the speakers will be stacked directly on the floor, stage, speaker stands, or a solid, stable platform. When placed on a smooth surface such as polished wood or linoleum, the speakers may move due to acoustical energy output. Precautions should be taken to assure that the speaker does not fall off the stage or table on which it is placed. Optional accessory items are available from JBL Professional and after-market suppliers to facilitate suspension and wall /ceiling mounting of EON speakers. Only those items recommended by JBL Professional should be used. When using these items, review all enclosed documentation and carefully follow all instructions and safety precautions.

CAUTION: Suspension of EON speakers should be done by qualified persons following safe rigging standards and practices. Unsafe mounting or overhead suspension of any heavy load can result in serious injury and equipment damage.

CAUTION: When suspending this product carefully follow JBL instructions and local ordinances. Do not attempt to use unless you have read and understood all instructions including the JBL User’s Guide. Attachment of the loudspeaker to a supporting structure should be referred to a qualified professional.

Stand Mounting Safety Precautions

EON series full range models include a 36 mm receptacle cup to allow mounting on tripod stands or on a pole over subwoofers. When using stands or poles, be sure to observe the following precautions:

•EON speakers include a thumb-screw that must be tightened to secure the speaker to the tripod stand. Before mounting the speaker on the stand, be sure to loosen the screw so that it doesn’t prevent the pole from fully penetrating the socket.

•Check the stand or pole specification to be certain the device is designed to support the weight of the speaker. Observe all safety precautions specified by the manufacturer.

•Always verify that the stand (or subwoofer/pole) is placed on a flat, level and stable surface and be sure to fully extend the legs of tripod type stands. Position the stand so that the legs do not present a trip hazard.

•Route cables so that performers, production crew, and audience will not trip and topple the speakers over.

•Inspect the stand (or pole and associated hardware) before each use and do not use equipment with worn, damaged or missing parts.

•Do not attempt to place more than one EON series speaker on a stand or pole.

•Always be cautious in windy, outdoor conditions. It may be necessary to place additional weight (i.e. sandbags) on the base of the stand to improve stability. Avoid attaching banners or similar items to any part of a speaker system. Such attachments could act as a sail and topple the system.

•Unless you are confident that you can handle the weight of the speaker, ask another person to help you get it onto the tripod stand or pole.

Hearing Damage, Prolonged Exposure to Excessive SPL

EON series loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause permanent hearing damage to performers, production crew and audience members. Caution should be taken to avoid prolonged exposure to SPL in excess of 90 dB.
