Keep the exterior of the speaker enclosure clean. Use a damp rag with a general-purpose 
household detergent. For grease and marking tape residue, use a damp cloth with isopropyl
alcohol or mineral spirits and wipe dry. Do not use powerful solvents like acetone, MEK,
lacquer thinner or 1,1,1-Trichloro-ethane (household cleaning fluid). These solvents will 
damage painted and co-polymer surfaces of your speakers.

EON speakers are not intended for fixed installation in outdoor environments. Moisture can 
damage the speaker cone and surround, cause corrosion of electrical contacts, and create 
an electrical shock hazard. Protect your speakers from moisture. Avoid exposing the speakers 
to direct moisture. Any electrically powered device can produce dangerous shock hazards 
when wet or exposed to moisture. Keep speakers out of extended or intense direct sunlight.
The driver suspension will prematurely dry out and finished surfaces will be degraded by 
long-term exposure to intense ultra-violet (UV) light.

The EON Sub G2 contains no user serviceable parts. Refer servicing to an authorized JBL 
service agency.

Stand Mounting and Precautions

Your EON speakers include a 35mm receptacle cup to facilitate mounting on tripod stands. When
using stands, be sure to observe the following precautions:

EON speakers include a thumb-screw that can be tightened to lock 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 specification to be certain it is designed to support the weight of the speaker 
(see specifications). Observe all safety precautions specified by the stand manufacturer.

Always verify that the stand is placed on a flat, level, and stable surface.

Route cables so that performers, production crew, and audience will not trip over them and pull 
the speaker over.

Be sure to fully extend the legs of tripod type stands.

Position the stand so that the legs do not present a trip hazard.

Do not attempt to place more than one speaker on a stand designed for a single speaker.

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.

The EON Sub G2 generates considerable energy. When placed on a slippery surface such as 
polished wood or linoleum, the EON Sub G2 may move due to its acoustical energy output. 
Precautions should be taken to assure that the speaker does not fall off a stage or table on 
which it is placed. One solution is to place the speaker on a rubber mat.

Electrical Safety

All EON powered series speakers are fitted with a detachable power cord (supplied) which connects
to the AC mains on the back panel of the loudspeaker. The power cord has an IEC female connector
on one end and a male mains connector on the other end. This cord is supplied to accommodate
the different worldwide safety and electrical code requirements. If the power cord supplied with your
EON product has a 3-pin type plug do not cut off or damage the grounding plug. Like any electrical
appliance, your EON powered speakers should not be used in water or when wet.
