44CONTROLS/ADJUSTMENTSThe L100 Classic has front-panel adjustments that let you balancethe levels of the midrange driver (MF) and tweeter (HF) relative tothe woofer.You can use these controls to adjust the speaker’s sound accordingto your room’s acoustics, or your personal taste. The “0dB” defaultposition is a good place to start. Whatever sounds best to you inyour room is the right setting.As with most speakers, after you start playing the L100 Classic itwill take the drivers’ suspensions several weeks to “break in” andachieve optimum performance. During this period, the balancebetween the woofer, midrange, and tweeter may change, so werecommendthat you adjust the midrange and tweeter controls again after the break-in period.NOTE: There is a protective plastic film on the front control panel label that may be removed.CARING FOR YOUR SPEAKERS• Wipe the cabinet with a clean, dry cloth to remove dust.
