CONTROLS/ADJUSTMENTS
The 4312SE has front-panel adjustments that let you balance the levels of
Midrange
Control
Tweeter
Control
the midrange driver (MF) and tweeter (HF) relative to the woofer.
You can use these controls to adjust the speaker’s sound according to your
room’s acoustics, or your personal taste. The “center” default position is with
the marks on the knobs pointing towards the number five.
As with most speakers, after you start playing the 4312SE it will take the
drivers’ suspensions several weeks to “break in” and achieve optimum
performance. During this period, the balance between the woofer, midrange
and tweeter may change, so we recommend that you adjust the midrange
and tweeter controls accordingly.
NOTE: There is a protective plastic film on the front control panel label and back panel model name plate. This
may be removed upon installation.
CARING FOR YOUR SPEAKERS
• 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 grille fabric, use a vacuum cleaner set to low suction.
• Do not wash the grille in water, as this may fade the color or make it uneven.
• If the surfaces of the woofer and midrange cones become dusty, you can carefully sweep them clean with
a soft, dry calligraphy brush or paint brush. Do not use a damp cloth.
• NEVER touch anything to the tweeter dome.
