Bass is very weak AND/OR sound
seems to come from each speaker
separately, without creating a
stable stereo image between the
speakers.
1. The polarity (+ & –) of one
speaker has been reversed
relative to the other. Double 
check connections.
2. Speakers are too far away from
back and side walls or too far
apart.  Experiment again with the
speaker placement. If you are still
encountering problems, consult
your JBL dealer.

GENERAL CARE
The grille is held in place by pins
near the edges. To remove the
grille, grasp it by both top and
bottom edges and pull gently. 
To replace grille, re-position it
carefully and press gently at the
corners. Do not push on the center
area of the grille.

The loudspeaker cabinet may be
cleaned with a slightly damp cloth.
To remove dust from the grille
cloth, use a vacuum with a brush
attachment. Spots may be
removed with a commercial spot
remover. Do not use any cleaners
or solvents on the speaker drivers
themselves.
