7. Controls/Adjustments
The 4319 has front-panel adjustments that let you balance the levels of the midrange driver (MF) and tweeter (HF)
against the woofer.
You can use these controls to adjust the speaker’s sound according to your room’s acoustics, or your personal taste. The
0dB positions are indicated.
As with most speakers, after you start playing the 4319 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.
8. 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.
