COnTrOLs/aDJusTMenTs

The L100 Classic 75 has front-panel adjustments that let you balance the
levels of 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 "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 L100 Classic 75 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 again after the break-in period.
NOTE: There is a protective plastic film on the front control panel label that may be removed.
