Caring For Your Speakers - Harman JBL L52 Classic Manual

COnTrOLs/aDJusTMenTs
The L52 Classic has a front-panel adjustment that lets you balance the level
of the tweeter (HF) relative to the woofer.
You can use this control to adjust the tweeter balance to the woofer, to
change the speaker's sound. The "0dB" default position is a good place to
start. Whatever sounds best to you in your room is the right setting.
As with most speakers, after you start playing the L52 Classic it will take
the drivers' suspensions several weeks to "break in" and achieve optimum
performance. During this period, this tweeter balance may change, so we
recommend that you adjust the tweeter control again after the break-in
period.
NOTE: There is a protective plastic film on the front control panel label that
may be removed.

• Wipe the cabinet with a clean, dry cloth to remove dust. Damp cloths or cleaning paper may dull the cabinet's
finish.
• Do not use volatile liquids such as benzene, paint thinner, alcohol, etc., on the cabinet. Do not spray insecticide
near the cabinet.
• To remove dust from the foam grille, use a vacuum cleaner set to low suction.
• Do not wash the grille in water.
• If the surfaces of the woofer and midrange cones become dusty, you can carefully sweep them clean with a soft,
dry calligraphy brush or paintbrush. Do not use a damp cloth.
• NEVER touch anything to the tweeter dome.
